• Use These DNS Servers. If you know that your ISP does not  
automatically transmit DNS addresses to the N300 wireless modem  
router during login, select this option, and enter the IP address of your  
ISP’s primary DNS server. If a secondary DNS server address is  
available, enter it also.  
NAT (Net Address Translation)  
NAT automatically assigns private IP addresses (10.1.1.x) to  
LAN-connected devices.  
• Enable. Usually NAT is enabled.  
• Disable. This disables NAT, but leaves the firewall active. Disable NAT  
only if you are sure that you do not require it. When NAT is disabled,  
only standard routing is performed by this router. Classical routing lets  
you directly manage the IP addresses that the N300 wireless modem  
router uses. Classical routing should be selected only by experienced  
a
users .  
• Disable firewall. This disables the firewall in addition to disabling NAT.  
With the firewall disabled, the protections usually provided to your  
network are disabled.

Protecting your network  
For a wireless connection, the SSID, also called the wireless network name, and the wireless  
security setting must be the same for the N300 wireless modem router and wireless  
computers or wireless adapters. NETGEAR strongly recommends that you use wireless  
security.  
WARNING!  
Computers can connect wirelessly at a range of several hundred  
feet. This can allow others outside of your immediate area to  
access your network.

Push 'N' Connect (WPS) automatically implements wireless security on the N300 wireless  
modem router while, at the same time, allowing you to automatically implement wireless  
security on any WPS-enabled devices (such as wireless computers and wireless adapter  
cards). You activate WPS by pressing a WPS button on the N300 wireless modem router,  
clicking an onscreen WPS button, or entering a PIN number. This generates a new SSID  
and implements WPA/WPA2 security.  
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi  
Protected Setup (WPS) standard (for more information, see  
http://www.wi-fi.org). All other Wi-Fi-certified and WPS-capable  
products should be compatible with NETGEAR products that  
implement Push 'N' Connect.  
To set up your wireless network using the WPS feature:  
-
Use the N300 wireless modem router dome, which works as a WPS button (there is  
also an onscreen WPS button), or enter the PIN of the wireless device.  
-
Make sure that all wireless computers and wireless adapters on the network are Wi-Fi  
certified and WPA or WPA2 capable, and that they support WPS configuration.  
See Using Push 'N' Connect (WPS) to Configure Your Wireless Network on page 24.  
Wireless Placement and Range Guidelines  
The range of your wireless connection can vary significantly based on the physical placement  
of the N300 wireless modem router. The latency, data throughput performance, and notebook  
power consumption of wireless adapters also vary depending on your configuration choices.  
For best results, place your N300 wireless modem router according to the following  
guidelines:  
•
•
Near the center of the area in which your PCs will operate.  
In an elevated location such as a high shelf where the wirelessly connected PCs have  
line-of-sight access (even if through walls).  
•
•
Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz  
cordless phones (see Interference Reduction Table on page 169).  
Away from large metal surfaces.

•
Put the antenna in a vertical position to provide the best side-to-side coverage. Put the  
antenna in a horizontal position to provide the best up-and-down coverage.  
If you are using multiple access points, it is better if adjacent access points use different  
radio frequency channels to reduce interference. The recommended channel spacing  
between adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6  
and 11).  
The time it takes to establish a wireless connection can vary depending on both your security  
settings and placement. WEP connections can take slightly longer to establish. Also, WEP  
encryption can consume more battery power on a notebook computer.  
Wireless Security Options  
Indoors, computers can connect over 802.11g wireless networks at a maximum range of up  
to 300 feet. Such distances can allow for others outside your immediate area to access your  
network.  
Unlike wired network data, your wireless data transmissions can extend beyond your walls  
and can be received by anyone with a compatible adapter. For this reason, use the security  
features of your wireless equipment. The N300 wireless modem router provides highly  
effective security features, which are covered in detail in this chapter. Deploy the security  
features appropriate to your needs.  
There are several ways you can enhance the security of your wireless network:  
Wireless data  
1) Open system: easy but no security.  
2) WEP: security, but some performance impact.  
3) WPA-PSK: strong security.  
4) WPA2-PSK: very strong security.  
Figure 8.  
•
WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP  
Shared Key authentication and WEP data encryption block all but the most determined  
eavesdropper. This data encryption mode has been superseded by WPA-PSK and  
WPA2-PSK.  
•
WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared  
key to perform authentication and generate the initial data encryption keys. The very  
strong authentication along with dynamic per frame rekeying of WPA makes it virtually  
impossible to compromise.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
Using Push 'N' Connect (WPS) to Configure Your Wireless  
Network  
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to  
configure the N300 wireless modem router’s SSID and security settings and, at the same  
time, connect the wireless client securely and easily to the N300 wireless modem router.  
Look for the  
symbol on your client device (computers that will connect wirelessly to the  
N300 wireless modem router are clients). WPS automatically configures the network name  
(SSID) and wireless security settings for the N300 wireless modem router (if the N300  
wireless modem router is in its default state) and broadcasts these settings to the wireless  
client.  
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi  
Protected Setup (WPS) standard (for more information, see  
http://www.wi-fi.org). All other Wi-Fi-certified and WPS-capable  
products should be compatible with NETGEAR products that  
implement Push 'N' Connect.  
Some considerations regarding WPS are:  
•
WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not  
supported by WPS.  
•
If your wireless network will include a combination of WPS-capable devices and  
non-WPS-capable devices, NETGEAR suggests that you set up your wireless network  
and security settings manually first, and use WPS only for adding additional  
WPS-capable devices. See Adding Both WPS and Non-WPS Clients on page 28.  
You can add a WPS client using the Push Button method or the PIN method.  
•
Using the Push Button. This is the preferred method. See the following section, Using a  
WPS Button to Add a WPS Client .  
•
Entering a PIN. For information about using the PIN method, see Using PIN Entry to Add  
a WPS Client on page 25.  
Using a WPS Button to Add a WPS Client  
Any wireless computer or wireless adapter that will connect to the N300 wireless modem  
router wirelessly is a client. The client must support a WPS button, and must have a WPS  
configuration utility, such as the NETGEAR Smart Wizard or Atheros Jumpstart.  
To use the N300 wireless modem router WPS button to add a WPS client:  
1. Log in to the N300 wireless modem router at its default LAN address of  
http://192.168.0.1 or http://www.routerlogin.net with its default user name of admin

The N300 wireless modem router WPS screen displays a message confirming that the  
client was added to the wireless network. The N300 wireless modem router generates an  
SSID and implements WPA/WPA2 wireless security. The N300 wireless modem router  
will keep these wireless settings unless you change them or you clear the Keep Existing  
Wireless Settings check box in the Advanced Wireless Settings screen. See Restricting  
Access to Your N300 Wireless Modem Router on page 29.  
6. Note the new SSID and WPA/WPA2 password for the wireless network. You can view these  
settings in the Wireless Settings screen. See Manually Configuring Your Wireless Settings  
on page 18.  
To access the Internet from any computer connected to your N300 wireless modem router,  
launch a browser such as Microsoft Internet Explorer or Mozilla Firefox. You should see the  
N300 wireless modem router’s Internet LED blink, indicating communication to the ISP.  
Note: If no WPS-capable client devices are located during the 2-minute  
time frame, the SSID will not be changed, and no security will be  
implemented on the N300 wireless modem router.  
Using PIN Entry to Add a WPS Client  
Any wireless computer or wireless adapter that will connect to the N300 wireless modem  
router wirelessly is a client. The client must support a WPS PIN, and must have a WPS  
configuration utility, such as the NETGEAR Smart Wizard or Atheros Jumpstart.

Live Parental Controls  
NETGEAR Live Parental Controls, powered by OpenDNS, is a router-based Web filtering  
solution available on NETGEAR Wireless-N router and gateway products. Designed to  
protect you from identity theft and scams, Live Parental Control blocks up to 50 categories of  
Internet content.  
Live Parental Controls is an excellent solution for keeping your family safe online, but like all  
Web filtering tools, it is not perfect. NETGEAR reminds you there is no substitute for keeping  
the family computer in a common area and in plain sight where you can monitor the websites  
your kids are visiting, and taking caution when visiting websites requesting personal or  
financial information.  
Download Live Parental Controls from this website: http://www.netgear.com/lpc.  
Web-Based Interface  
Live Parental Controls is the first to allow parents or network administrators to manage  
settings while away from home or office. This is particularly convenient when access  
exceptions need to be made. And since settings are stored on the Web, using a browser  
interface to manage them is not difficult.  
Total Home Protection  
Live Parental Controls protects all Internet-connected devices through the router. It protects  
not only computers, but also set-top boxes, iPhones, iPods, and gaming consoles that are  
attached to your network. You no longer need to worry about phones and gaming consoles  
not being protected when kids use them in their own rooms. Even guest computers  
accessing the Internet through your network are protected.

Port Triggering  
Port triggering is an advanced feature that can be used to easily enable gaming and other  
Internet applications that would otherwise be blocked by the firewall. Using this feature  
requires that you know the port numbers that are used by the application.  
Note: For information about port forwarding and port blocking, see  
Firewall Rules on page 38.  
Once configured, port triggering operates as follows:  
1. A PC makes an outgoing connection using a port number defined in the Port Triggering  
table.  
2. The N300 wireless modem router records this connection, opens the incoming port or ports  
associated with this entry in the Port Triggering List, and associates them with the PC.  
3. The remote system receives the PC’s request, and responds using a different port number.  
4. The N300 wireless modem router matches the response to the previous request, and  
forwards the response to the PC. (Without port triggering, this response would be treated as  
a new connection request rather than a response. As such, it would be handled in  
accordance with the port forwarding rules.)  
Note: Only one PC can use a port triggering application at any time. After  
a PC has finished using a port triggering application, there is a short  
time-out period before the application can be used by another PC.  
To configure port triggering:  
1. In the main menu, select Security > Port Triggering. The Port Triggering screen  
displays.

Service User. The PC on the LAN that can use the port triggering rule to create a  
dynamic inbound mapping to it. There are 2 options:  
-
The port triggering rule is applied to all PCs on the LAN. That is, any PC on the  
LAN can use the rule and make the router to open a dynamic mapping to it.  
-
The port triggering rule is applied only to the user-specified PC on the LAN.  
•
•
Service Type. Defines whether the traffic is TCP or UDP.  
Triggering Port. The destination port number of the traffic. That is, when there is a  
packet from a LAN PC that the rule is applied to, with the specified service type and  
destined to the specified triggering port, the router creates a rule for dynamic mapping  
to the LAN PC.  
•
Required Inbound Connection. This defines what the dynamic mapping is. The  
connection type defines whether the dynamic mapping is for TCP traffic, UDP traffic,  
or TCP and UDP traffic. The open port range is specified by the starting port and the  
ending port, and this defines the port that the dynamic mapping is applied to.  
3. Click Apply to save your settings and activate the port triggers that you have enabled.  
Blocking Access to Internet Services  
The N300 wireless modem router allows you to block the use of certain Internet services by  
computers on your network. This is called service blocking or port filtering. Services are  
functions performed by server computers at the request of client computers. For example,  
Web servers serve Web pages, time servers serve time and date information, and game  
hosts serve data about other players’ moves. When a computer on your network sends a  
request for service to a server computer on the Internet, the requested service is identified by  
a service or port number. This number appears as the destination port number in the  
transmitted IP packets. For example, a packet that is sent with destination port number 80 is  
an HTTP (Web server) request.

modem router, go to:  
http://kbserver.netgear.com/kb_web_files/n101300.asp  
When selecting a USB device, bear in mind the following:  
•
The USB port on the N300 wireless modem router can be used with one USB hard drive  
at a time. Do not attempt to use a USB hub attached to the USB port.  
•
According to the USB 2.0 specification, the maximum available power is 5V @ 0.5A.  
Some USB devices might exceed this requirement, in which case the device might not  
function or might function erratically. Check the documentation for your USB device to be  
sure.  
•
•
The N300 wireless modem router supports FAT, FAT32, and NTFS (read only) file  
systems.  
If your USB HD devices have an external power supply, be sure to use it.  
File Sharing Scenarios  
You can share files on the USB drive for a wide variety of business and recreational  
purposes. The files can be any PC, Mac, or Linux file type including text files, Word,  
PowerPoint, Excel, MP3, pictures, and multimedia. USB drive applications include:  
•
Sharing multimedia with friends and family—sharing MP3 files, pictures, and other  
multimedia with local and remote users.  
•
Sharing resources on your network—storing files in a central location so that you do not  
have to power up a computer to perform local sharing. In addition, you can share files  
between Macintosh, Linux, and PC computers by using the USB drive as a go-between  
the systems.  
•
Sharing files with offsite coworkers—sharing files such as Word documents, PowerPoint  
presentations, and text files with remote users. A few common uses are described in the  
following sections.

Sharing Photos with Friends and Family  
You can create your own central storage location for photos and multimedia. This eliminates  
the need to log in to (and pay for) an external photo sharing site.  
To share files with your friends and family:  
1. Insert the USB drive into the N300 wireless modem router USB port either directly or  
with a USB cable.  
Computers on your local area network (LAN) can automatically access this USB drive  
using a Web browser or Microsoft Networking.  
2. If you want to specify read only access, or to allow access from the Internet, see Configuring  
USB Storage Advanced Settings on page 69 for information.  
Storing Files in a Central Location for Printing  
This scenario is for a family that has one high-quality color printer directly attached to a PC,  
but not shared on the local area network (LAN). This family does not have a print server:  
•
•
The daughter has some photos on her Macintosh computer that she wants to print.  
The mother has a photo-capable color printer directly attached to her PC, but not shared  
on the network.  
•
The mother’s and daughter’s computers are not visible to each other on the network.  
How can the daughter print her photos on the color printer attached to her mother’s PC? This  
is where the USB drive on the N300 wireless modem router can save you time and effort.  
1. The daughter accesses the USB drive by typing \\readyshare in the address field of her  
Web browser. Then she copies the photos to the USB drive.  
2. The mother uses a her Web browser or Microsoft Networking to transfer the files from the  
USB drive to the PC. Then she prints the files.  
Sharing Large Files with Colleagues  
Sending files that are larger than 5 MB can pose a problem for many email systems. The  
N300 wireless modem router allows you to share very large files such as PowerPoint  
presentations or .zip files with colleagues at another site. Rather than tying up their mail  
systems with large files, your colleagues can use FTP to easily download shared files from  
the N300 wireless modem router.  
Sharing files with a remote colleague involves the following steps:  
1. To protect your network, set up appropriate security. Create a user name and password  
for the colleague with appropriate access.  
2. If you want to limit USB drive access to read only access, from the N300 wireless modem  
router USB Storage (Basic Settings) screen, click Edit a Network folder. In the Write  
Access field, select Edit, and then click Apply.

A VPN client access allows a remote PC to connect to your network from any location on the  
Internet. The remote PC is one tunnel endpoint, running the VPN client software. The N300  
wireless modem router on your network is the other tunnel endpoint. See Setting Up a  
Client-to-Gateway VPN Configuration on page 80 for information about how to set up this  
configuration.  
Gateway-to-Gateway VPN Tunnels  
Gateway-to-gateway VPN tunnels provide secure access between networks, such as a

A VPN between two or more NETGEAR VPN-enabled routers is a good way to connect  
branch or home offices and business partners over the Internet. VPN tunnels also enable  
access to network resources across the Internet. In this case, use gateways on each end of  
the tunnel to form the VPN tunnel end points. See Setting Up a Gateway-to-Gateway VPN  
Configuration on page 90 for information about how to set up this configuration.

To set up a VPN connection, you must configure each endpoint with specific identification and  
connection information describing the other endpoint. You must configure the outbound VPN  
settings on one end to match the inbound VPN settings on other end, and vice versa.  
This set of configuration information defines a security association (SA) between the two  
VPN endpoints. When planning your VPN, you must make a few choices first:  
•
•
•
Will the local end be any device on the LAN, a portion of the local network (as defined by  
a subnet or by a range of IP addresses), or a single PC?  
Will the remote end be any device on the remote LAN, a portion of the remote network (as  
defined by a subnet or by a range of IP addresses), or a single PC?  
Will either endpoint use fully qualified domain names (FQDNs)? FQDNs supplied by  
Dynamic DNS providers (see Using a Fully Qualified Domain Name (FQDN) on  
page 154) can allow a VPN endpoint with a dynamic IP address to initiate or respond to a  
tunnel request. Otherwise, the side using a dynamic IP address must always be the  
initiator.

3DES. Triple DES achieves a higher level of security by encrypting the data three  
times using DES with three different, unrelated keys.  
What level of authentication will you use?  
-
MDS. 128 bits, faster but less secure.  
-

VPN Tunnel Configuration  
There are two tunnel configurations and three ways to configure them:  
•
Use the VPN Wizard to configure a VPN tunnel (recommended for most situations):  
-
See Setting Up a Client-to-Gateway VPN Configuration on page 80.  
-
See Setting Up a Gateway-to-Gateway VPN Configuration on page 90.

See Using Auto Policy to Configure VPN Tunnels on page 101 when the VPN Wizard and  
its VPNC defaults (see Table 2 on page 79) are not appropriate for your special  
circumstances, but you want to automate the Internet Key Exchange (IKE) setup.  
See Using Manual Policy to Configure VPN Tunnels on page 109 when the VPN Wizard  
and its VPNC defaults (see Table 2 on page 79) are not appropriate for your special  
circumstances and you must specify each phase of the connection. You manually enter  
all the authentication and key parameters. You have more control over the process;  
however, the process is more complex, and there are more opportunities for errors or

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
•
Manual Policy. For a manual keying setup in which you must specify each phase of the  
connection, see Using Manual Policy to Configure VPN Tunnels on page 109. Manual  
policy does not use IKE. Rather, you manually enter all the authentication and key  
parameters. You have more control over the process; however, the process is more  
complex, and there are more opportunities for errors or configuration mismatches  
between your N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 and the  
corresponding VPN endpoint gateway or client workstation.  
Using Auto Policy to Configure VPN Tunnels  
You need to configure matching VPN settings on both VPN endpoints. The outbound VPN  
settings on one end must match to the inbound VPN settings on other end, and vice versa.  
For an example of using Auto Policy, see Example of Using Auto Policy on page 106.  
Configuring VPN Network Connection Parameters  
All VPN tunnels on the N300 wireless modem router require that you configure several  
network parameters. This section describes those parameters and how to access them.  
The most common configuration scenarios use IKE to manage the authentication and  
encryption keys. The IKE protocol performs negotiations between the two VPN endpoints to  
automatically generate and update the required encryption parameters.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
Table 5. VPN - Auto Policy Screen Settings (Continued)  
Fields and Settings  
Description  
IKE  
Direction  
This setting is used when the router determines if the IKE policy  
matches the current traffic. Select an option.  
• Responder only. Incoming connections are allowed, but outgoing  
connections are blocked.  
• Initiator and Responder. Both incoming and outgoing connections  
are allowed.  
Exchange Mode  
Ensure that the remote VPN endpoint is set to use Main Mode.  
Diffie-Hellman  
(DH) Group  
The Diffie-Hellman algorithm is used when keys are exchanged. The  
DH Group setting determines the bit size used in the exchange. This  
value must match the value used on the remote VPN gateway.  
Local Identity Type Select an option to match the Remote Identity Type setting on the  
remote VPN endpoint.  
• WAN IP Address. Your Internet IP address.  
• Fully Qualified Domain Name. Your domain name.  
• Fully Qualified User Name. Your name, email address, or other ID.  
Local Identity Data Enter the data for the local identity type that you selected. (If WAN IP  
Address is selected, no input is required.)  
Remote Identity  
Type  
Select the option that matches the Local Identity Type setting on the  
remote VPN endpoint.  
• IP Address. The Internet IP address of the remote VPN endpoint.  
• Fully Qualified Domain Name. The domain name of the remote  
VPN endpoint.  
• Fully Qualified User Name. The name, email address, or other ID of  
the remote VPN endpoint.  
Remote Identity  
Data  
Enter the data for the remote identity type that you selected. If IP  
Address is selected, no input is required.  
Parameters  
Encryption  
Algorithm  
The encryption algorithm used for both IKE and IPSec. This setting  
must match the setting used on the remote VPN gateway. DES and  
3DES are supported.  
• DES. The Data Encryption Standard (DES) processes input data that  
is 64 bits wide, encrypting these values using a 56-bit key. Faster but  
less secure than 3DES.  
• 3DES. (Triple DES) achieves a higher level of security by encrypting  
the data three times using DES with three different, unrelated keys.  
Authentication  
Algorithm  
The authentication algorithm used for both IKE and IPSec. This setting  
must match the setting used on the remote VPN gateway. Auto, MD5,  
and SHA-1 are supported. Auto negotiates with the remote VPN  
endpoint and is not available in responder-only mode.  
• MD5. 128 bits, faster but less secure.  
• SHA-1. 160 bits, slower but more secure. This is the default.  
Pre-shared Key  
The key must be entered both here and on the remote VPN gateway.

Parameters  
(Continued)  
SA Life Time  
The time interval before the SA (security association) expires. (It is  
automatically reestablished as required.) While using a short time  
period (or data amount) increases security, it also degrades  
performance. It is common to use periods over an hour (3600 seconds)  
for the SA life-time. This setting applies to both IKE and IPSec SAs.  
Enable IPSec PFS • If this check box is selected, security is enhanced by ensuring that  
(Perfect Forward  
Secrecy)  
the key is changed at regular intervals. Also, even if one key is  
broken, subsequent keys are no easier to break. (Each key has no  
relationship to the previous key.)  
• This setting applies to both IKE and IPSec SAs. When configuring  
the remote endpoint to match this setting, you might have to specify  
the key group used. For this device, the key group is the same as the  
DH Group setting in the IKE section.  
General  
Policy Name  
Enter a unique name to identify this policy. This name is not supplied to  
the remote VPN endpoint. It is used only to help you manage the  
policies.  
Remote VPN  
Endpoint  
• The remote VPN endpoint must have this VPN gateway's address  
entered as its remote VPN endpoint.  
• If the remote endpoint has a dynamic IP address, select Dynamic IP  
address. No address data input is required. You can set up multiple  
remote dynamic IP policies, but only one such policy can be enabled  
at a time. Otherwise, select an option (IP address or domain name)  
and enter the address of the remote VPN endpoint to which you want  
to connect.  
IKE Keep Alive  
• If you want to ensure that a connection is kept open, or, if that is not  
possible, that it is quickly reestablished when disconnected, select  
this check box.  
• The ping IP address must be associated with the remote endpoint.  
The remote LAN address must be used. This IP address will be  
pinged periodically to generate traffic for the VPN tunnel. The remote  
keep-alive IP address must be covered by the remote LAN IP range  
and must correspond to a device that can respond to ping. The range  
should be made as narrow as possible to meet this objective.  
Local LAN  
Subnet Mask  
Enter the network mask.  
The remote VPN  
endpoint must  
have these IP  
addressesentered  
as its remote  
addresses.  
Single/Start IP  
Address  
• Enter the IP address for a single address, or the starting address for  
an address range. A single address setting is used when you want to  
make a single server on your LAN available to remote users. A range  
must be an address range used on your LAN.  
• Any. The remote VPN endpoint might be at any IP address.

Using the LAN Setup Options  
The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host  
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).  
The N300 wireless modem router is shipped preconfigured to use private IP addresses on  
the LAN side and to act as a DHCP server. The N300 wireless modem router’s default LAN  
IP configuration is:  
•
•
LAN IP address. 192.168.0.1  
Subnet mask. 255.255.255.0  
These addresses are part of the designated private address range for use in private  
networks and should be suitable for most applications. If your network has a requirement to  
use a different IP addressing scheme, you can make those changes in the LAN Setup  
screen.  
To configure LAN settings, log in to the N300 wireless modem router, and from the main  
menu, select Advanced > LAN Setup. The following screen displays:

Description  
LAN TCP/IP  
Setup  
IP Address  
The LAN IP address of the N300 wireless modem router.  
IP Subnet Mask  
The LAN subnet mask of the N300 wireless modem router.  
Combined with the IP address, the IP subnet mask allows a  
device to know which other addresses are local to it, and  
which must be reached through a gateway or N300 wireless  
modem router.  
RIP Direction  
RIP (Router Information Protocol) allows the N300 wireless  
modem router to exchange routing information with other  
routers. This setting controls how the N300 wireless modem  
router sends and receives RIP packets. Both is the default.  
• Both or Out Only. The N300 wireless modem router  
broadcasts its routing table periodically.  
• Both or In Only. The N300 wireless modem router  
incorporates the RIP information that it receives.  
• None. The N300 wireless modem router will not send any  
RIP packets and will ignore any RIP packets received.  
RIP Version  
This controls the format and the broadcasting method of the  
RIP packets that the N300 wireless modem router sends. It  
recognizes both formats when receiving. By default, this is  
RIP-1.  
• RIP-1 is universally supported. It is adequate for most  
networks, unless you have an unusual network setup.  
• RIP-2 carries more information. Both RIP-2B and RIP-2M  
send the routing data in RIP-2 format. RIP-2B uses subnet  
broadcasting. RIP-2M uses multicasting.  
DHCP Server  
Use Router as a DHCP  
Server  
This check box is usually selected so that the N300 wireless  
modem router functions as a Dynamic Host Configuration  
Protocol (DHCP) server. See Using the N300 Wireless  
Modem Router as a DHCP Server on page 114.  
Starting IP Address  
Ending IP Address  
Specify the start of the range for the pool of IP addresses in  
the same subnet as the N300 wireless modem router.  
Specify the end of the range for the pool of IP addresses in the  
same subnet as the N300 wireless modem router.  
Address Reservation  
When you specify a reserved IP address for a computer on  
the LAN, that computer receives the same IP address each  
time it accesses the N300 wireless modem router’s DHCP  
server. Assign reserved IP addresses to servers that require  
permanent IP settings.  
For more information, see Address Reservation  
on page 115.  
Using the N300 Wireless Modem Router as a DHCP Server  
By default, the N300 wireless modem router functions as a DHCP server, allowing it to assign  
IP, DNS server, and default gateway addresses to all computers connected to the N300  
wireless modem router’s LAN. The assigned default gateway address is the LAN address of  
the N300 wireless modem router. The N300 wireless modem router assigns IP addresses to

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
the attached computers from a pool of addresses specified in this screen. Each pool address  
is tested before it is assigned to avoid duplicate addresses on the LAN.  
For most applications, the default DHCP and TCP/IP settings of the N300 wireless modem  
router are satisfactory. Click the link to the online document TCP/IP Networking Basics on  
page 172 for an explanation of DHCP and information about how to assign IP addresses for  
your network.  
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending  
IP address. These addresses should be part of the same IP address subnet as the N300  
wireless modem router’s LAN IP address. Using the default addressing scheme, you should  
define a range between 192.168.0.2 and 192.168.0.254, although you might wish to save  
part of the range for devices with fixed addresses.  
The N300 wireless modem router delivers the following parameters to any LAN device that  
requests DHCP:  
•
•
•
•
An IP Address from the range you have defined  
Subnet Mask  
Gateway IP Address (the N300 wireless modem router’s LAN IP address)  
Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen;  
otherwise, the N300 wireless modem router’s LAN IP address)  
•
Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings  
screen)  
To use another device on your network as the DHCP server, or to manually configure the  
network settings of all of your computers, clear the Use Router as DHCP Server check box.  
Otherwise, leave it selected. If this service is not selected and no other DHCP server is  
available on your network, you will need to set your computers’ IP addresses manually or  
they will not be able to access the N300 wireless modem router.  
Address Reservation  
When you specify a reserved IP address for a computer on the LAN, that computer always  
receives the same IP address each time it accesses the N300 wireless modem router’s  
DHCP server. Reserved IP addresses should be assigned to computers or servers that  
require permanent IP settings.  
To reserve an IP address:  
1. Click Add.  
2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an  
IP address from the N300 wireless modem router’s LAN subnet, such as 192.168.0.x.)  
3. Type the MAC address of the computer or server.  
Tip: If the computer is already present on your network, you can copy its  
MAC address from the Attached Devices screen and paste it here.

4. Click Apply to enter the reserved address into the table.  
Note: The reserved address is not assigned until the next time the  
computer contacts the N300 wireless modem router’s DHCP server.  
Reboot the computer or access its IP configuration and force a  
DHCP release and renew.  
To edit or delete a reserved address entry:  
1. Select the radio button next to the reserved address you want to edit or delete.  
2. Click Edit or Delete.  
Using a Dynamic DNS Service  
If your Internet Service Provider (ISP) gave you a permanently assigned IP address, you can  
register a domain name and have that name linked with your IP address by public Domain  
Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP  
address, you do not know in advance what your IP address will be, and the address can  
change frequently. In this case, you can use a commercial Dynamic DNS service, which  
allows you to register your domain to its IP address, and forwards traffic directed at your  
domain to your frequently changing IP address.  
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x  
or 10.x.x.x), the Dynamic DNS service will not work because private  
addresses are not routed on the Internet.  
Your N300 wireless modem router contains a client that can connect to the Dynamic DNS  
service provided by DynDNS.org. You must first visit their website at www.dyndns.org and  
obtain an account and host name, which you configure in the N300 wireless modem router.  
Then, whenever your ISP-assigned IP address changes, your N300 wireless modem router  
automatically contacts the Dynamic DNS service provider, logs in to your account, and  
registers your new IP address. If your host name is hostname, for example, you can reach  
your N300 wireless modem router at hostname.dyndns.org.  
To configure Dynamic DNS:  
1. From the main menu, select Advanced > Dynamic DNS to display the Dynamic DNS  
screen.

Figure 56.  
2. Register for an account with one of the Dynamic DNS service providers whose names  
appear in the Service Provider list. For example, for DynDNS.org, select www.dyndns.org.  
3. Select the Use a Dynamic DNS Service check box.  
4. Select the name of your Dynamic DNS service provider.  
5. Type the host name (or domain name) that your Dynamic DNS service provider gave you.  
6. Type the user name for your Dynamic DNS account. This is the name that you use to log in  
to your account, not your host name.  
7. Type the password (or key) for your Dynamic DNS account.  
8. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can  
select the Use Wildcards check box to activate this feature. For example, the wildcard  
feature causes *.yourhost.dyndns.org to be aliased to the same IP address as  
yourhost.dyndns.org.  
9. Click Apply to save your configuration.  
Configuring the WAN Setup Options  
The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the  
Maximum Transmit Unit (MTU) size, and enable the N300 wireless modem router to respond  
to a ping on the WAN (Internet) port. From the main menu, under Advanced, click WAN  
Setup to view the WAN Setup screen.

The WAN Setup fields are described in the following table:  
Setting  
Description  
Connect Automatically, as  
Required  
Usually, this check box is selected, so that an Internet connection is made  
automatically whenever Internet-bound traffic is detected. If this causes high  
connection costs, you can clear the check box to disable this feature.  
If this setting is disabled, you must connect manually, using the screen that you  
access by clicking the Connection Status button on the Status screen.  
If you have an Always on connection, this setting has no effect.  
Enable PPPoE Relay  
Selecting this check box allows a PPPoE client on a local PC to connect to a  
remote PPPoE server with the N300 wireless modem router acting as a relay  
agent.  
Disable Port Scan and DOS The firewall protects your LAN against port scans and denial of service (DOS)  
Protection  
attacks. This protection should be disabled only in special circumstances.  
Default DMZ Server  
This feature is sometimes helpful when you are using some online games and  
videoconferencing. Be careful when using this feature because it makes the  
firewall security less effective. See Configuring Static Routes on page 123.  
Respond to Ping on Internet If you want the N300 wireless modem router to respond to a ping from the  
WAN Port  
Internet, select this check box. This should be used only as a diagnostic tool,  
since it allows your N300 wireless modem router to be discovered. Do not select  
this check box unless you have a specific reason to do so.  
MTU Size (in bytes)  
The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is  
1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs you might  
need to reduce the MTU. This is rarely required, and should not be done unless  
you are sure it is necessary for your ISP connection. See Changing the MTU  
Size on page 134.  
Disable SIP ALG  
The Session Initiation Protocol (SIP) Application Level Gateway (ALG) is  
enabled by default to optimize VoIP phone calls that use the SIP. The Disable  
SIP ALG check box allows you to disable the SIP ALG. Disabling the SIP ALG  
might be useful when running certain applications.

Setting Up a Default DMZ Server  
The default DMZ server feature is helpful when using some online games and  
videoconferencing applications that are incompatible with Network Address Translation  
(NAT). The N300 wireless modem router is programmed to recognize some of these  
applications and to work correctly with them, but there are other applications that might not  
function well. In some cases, one local computer can run the application correctly if that  
computer’s IP address is entered as the default DMZ server.  
WARNING!  
DMZ servers pose a security risk. A computer designated as the  
default DMZ server loses much of the protection of the firewall  
and is exposed to exploits from the Internet. If compromised, the  
DMZ server computer can be used to attack other computers on  
your network.  
Incoming traffic from the Internet is usually discarded by the N300 wireless modem router  
unless the traffic is a response to one of your local computers or a service that you have  
configured in the Port Forwarding screen. Instead of discarding this traffic, you can have it  
forwarded to one computer on your network. This computer is called the default DMZ server.  
The WAN Setup screen lets you configure a default DMZ server.  
To assign a computer or server to be a default DMZ server:  
1. In the last Default DMZ Server field, type the last digit of the IP address for that  
computer. To remove the default DMZ server, enter 0 (zero).  
2. Select the Default DMZ Server check box, and click Apply.  
Setting Up Quality of Service (QoS)  
Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of  
traffic ahead of others. The N300 wireless modem router can provide QoS prioritization over  
the wireless link and on the Internet connection.  
The N300 wireless modem router supports Wi-Fi Multimedia Quality of Service (WMM QoS)  
to prioritize wireless voice and video traffic over the wireless link. WMM QoS provides  
prioritization of wireless data packets from different applications based on four access  
categories: voice, video, best effort, and background. For an application to receive the  
benefits of WMM QoS, both it and the client running that application must be WMM enabled.  
Legacy applications that do not support WMM, and applications that do not require QoS, are  
assigned to the best effort category, which receives a lower priority than voice and video.

Configuring Static Routes  
Static routes provide additional routing information to your N300 wireless modem router.  
Under usual circumstances, the N300 wireless modem router has adequate routing  
information after it has been configured for Internet access, and you do not need to configure  
additional static routes. You must configure static routes only for unusual cases such as  
multiple routers or multiple IP subnets located on your network.  
As an example of when a static route is needed, consider the following case:

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
•
•
Your primary Internet access is through a cable modem to an ISP.  
You have an ISDN router on your home network for connecting to the company where  
you are employed. This router’s address on your LAN is 192.168.0.100.  
•
Your company’s network address is 134.177.0.0.  
When you first configured your N300 wireless modem router, two implicit static routes were  
created. A default route was created with your ISP as the gateway, and a second static route  
was created to your local network for all 192.168.0.x addresses. With this configuration, if you  
attempt to access a device on the 134.177.0.0 network, your N300 wireless modem router  
forwards your request to the ISP. The ISP forwards your request to the company where you  
are employed, and the request is likely to be denied by the company’s firewall.  
In this case you must define a static route, telling your N300 wireless modem router that  
134.177.0.0 should be accessed through the ISDN router at 192.168.0.100.  
In this example:  
•
The Destination IP Address and IP Subnet Mask fields specify that this static route applies  
to all 134.177.x.x addresses.  
•
The Gateway IP Address field specifies that all traffic for these addresses should be  
forwarded to the ISDN router at 192.168.0.100.  
•
•
A Metric value of 1 will work since the ISDN router is on the LAN.  
Private is selected only as a precautionary security measure in case RIP is activated.  
From the main menu, select Advanced > Static Routes. The Static Routes screen displays.

To add or edit a static route:  
1. Click Add to open the Static Routes screen.

2. In the Route Name field, type a name for this static route. (This is for identification purposes  
only.)  
3. Select the Private check box if you want to limit access to the LAN only. If Private is  
selected, the static route is not reported in RIP.  
4. Select the Active check box to make this route effective.  
5. Type the destination IP address of the final destination.  
6. Type the IP subnet mask for this destination.  
If the destination is a single host, type 255.255.255.255.  
7. Type the gateway IP address, which must be a router on the same LAN segment as the  
N300 wireless modem router.  
8. Type a number between 1 and 15 as the metric value.  
This represents the number of routers between your network and the destination. Usually,  
a setting of 2 or 3 works, but if this is a direct connection, set it to 1.  
9. Click Apply to have the static route entered into the table.  
Wireless Repeating (Also Called WDS)  
The N300 Wireless Modem Router can be used with a wireless access point (AP) to build  
large bridged wireless networks. Wireless repeating is a type of Wireless Distribution System  
(WDS).  
WARNING!  
If you use the wireless repeating function, your options for  
wireless security are limited to None or WEP. For more  
information about wireless security, see Chapter 2, Wireless  
Settings.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
The following figure shows a wireless repeating scenario:  
Base Station AP  
Repeater AP  
Figure 66.  
To set up a wireless network using WDS, the following conditions must be met for both APs:  
•
Both APs must use the same SSID, wireless channel, and encryption mode (see  
Manually Configuring Your Wireless Settings on page 18 or Using Push 'N' Connect  
(WPS) to Configure Your Wireless Network on page 24).  
•
•
•
Both APs must be on the same LAN IP subnet. That is, all the AP LAN IP addresses are  
in the same network.  
All LAN devices (wired and wireless computers) must be configured to operate in the  
same LAN network address range as the APs.  
When the N300 wireless modem router is in dual band mode (the Mode field on the  
Wireless Settings screen is set to Up to 300 Mbps at 5 GHz and 54 Mbps at 2.4 GHz), the  
WDS function works only in 5 GHz 11N mode. To use the 2.4 GHz 11g protocol with  
WDS, set the Mode field in the Wireless Settings screen to Up to 300 Mbps at 2.4 GHz. If  
you make changes in the Wireless Settings screen, click Apply so that they take effect.  
Wireless Repeating Function  
You can view or change wireless repeater settings for the N300 wireless modem router. From  
the main menu of the browser interface, under Advanced, click Wireless Repeating Function  
to display the Wireless Repeating Function screen.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
Figure 67.  
The N300 wireless modem router supports two modes of the wireless repeating function, and  
allows you to control wireless client association:  
•
Wireless Repeater. The N300 wireless modem router sends all traffic from its local  
wireless or wired computers to a remote AP. To configure this mode, you must know the  
MAC address of the remote parent AP.  
•
Wireless Base Station. The N300 wireless modem router acts as the parent AP, bridging  
traffic to and from the child repeater AP, as well as handling wireless and wired local  
computers. To configure this mode, you must know the MAC addresses of the child  
repeater AP.  
•
Disable Wireless Client Association. Usually this check box is cleared so that the N300  
wireless modem router is an access point for wireless computers.  
If this check box is selected, the N300 wireless modem router communicates wirelessly  
only with other APs whose MAC addresses are listed in this screen. The N300 wireless  
modem router still communicates with wire-connected LAN devices.  
Setting Up the Base Station  
The wireless repeating function works only in hub and spoke mode. The units cannot be  
daisy chained. You must know the wireless settings for both units. You must know the MAC  
address of the remote unit. First, set up the base station, and then set up the repeater.  
To set up the base station:  
1. Set up both units with exactly the same wireless settings (SSID, mode, channel, and  
security). Note that the wireless security option must be set to None or WEP.  
2. Log in to the N300 wireless modem router base unit. Select Advanced > Wireless  
Repeating Function to display the Wireless Repeating Function screen.

Setting Up a Repeater Unit  
Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the wireless  
connection to the base station.  
Note: If you are using the N300 Wireless Dual Band ADSL2+ Modem  
Router DGND3300v2 base station with a non-NETGEAR N300  
wireless modem router as the repeater, you might need to change  
additional configuration settings. In particular, you should disable the  
DHCP server function on the wireless repeater AP.  
To configure a N300 wireless modem router as a repeater unit:  
1. If you are using the same model of N300 wireless modem router for both the base  
station and repeaters, you must change the LAN IP address for each repeater to a  
different IP address in the same subnet (see Using the LAN Setup Options on  
page 112).  
Note: Failing to change the LAN IP address will cause an IP address  
conflict in the network because the factory default LAN IP is the  
same for both units.

2. Log in to the router that will be the repeater. Check the Wireless Settings screen, and verify  
that the wireless settings match the base unit exactly. The wireless security option must be  
set to WEP or None.  
3. In the Wireless Repeating Function screen, select the Enable Wireless Repeater Mode  
radio button.  
This IP address must be in the same subnet as the base station but different from the  
LAN IP of the base station.  
4. Fill in the Base Station MAC Address field.  
5. Click Apply to save your changes.  
6. Verify connectivity across the LANs.  
A computer on any wireless or wired LAN segment of the N300 wireless modem router  
should be able to connect to the Internet or share files and printers with any other  
wireless or wired computer or server connected to the other AP.

Fine-tuning your network  
This chapter describes features to help you manage your N300 Wireless Dual Band ADSL2+  
Modem Router DGND3300v2.  
This chapter includes the following sections:

•
•
•
Common Connection Types on page 130

Optimizing Your Network Bandwidth on page 132  
Optimizing Wireless Performance on page 133

Universal Plug and Play on page 135  
Common Connection Types  
Common connection types and their speed and security considerations are:  
•
Broadband Internet. Your Internet connection speed is determined by your modem type,  
(ADSL), as well as the connection speed of the sites to which you connect, and general  
Internet traffic. ADSL modem connections are asymmetrical, meaning they have a lower  
data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind  
that when you connect to another site that also has an asymmetrical connection, the data  
rate between your sites is limited by each side’s upstream data rate. A typical residential  
ADSL connection provides a downstream throughput of about 1 to 3 megabits per  
second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) will  
increase the connection speed to tens of Mbps.  
•
Wireless. Your N300 wireless modem router provides a wireless data throughput of up to  
300 Mbps using technology called multiple input, multiple output (MIMO), in which  
multiple antennas transmit multiple streams of data. The use of multiple antennas also  
provides excellent range and coverage. With the introduction of the newer WPA and  
WPA2 encryption and authentication protocols, wireless security is extremely strong.  
To get the best performance, use RangeMax NEXT adapters for your computers.  
Although your N300 wireless modem router is compatible with older 802.11b and 802.11g  
adapters, the use of these older wireless technologies in your network can result in lower  
throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for  
Chapter 8. Advanced Settings (Part 2)

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
802.11g). In addition, many older wireless products do not support the latest security  
protocols, WPA and WPA2.  
•
Powerline. For connecting rooms or floors that are blocked by obstructions or are distant  
vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD  
family of products delivers up to 200 Mbps to any outlet, while the older-generation XE  
family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for  
security, and you can configure an individual network password to prevent neighbors from  
connecting.  
•
•
The Powerline HD family of products can coexist on the same network with  
older-generation XE family products or HomePlug 1.0 products, but they are not  
interoperable with these older products.  
Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common  
on newer computers, wired Ethernet remains a good choice for speed, economy, and  
security. Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e  
or better. A wired connection is not susceptible to interference, and eavesdropping would  
require a physical connection to your network.  
Note: Actual data throughput will vary. Network conditions and  
environmental factors, including volume of network traffic, building  
materials and construction, and network overhead, can lower actual  
data throughput rate.  
Assessing Your Speed Requirements  
Because your Internet connection is likely to operate at a much lower speed than your local  
network, faster local networking technologies might not improve your Internet experience.  
However, many emerging home applications require high data rates. For example:  
•
Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss  
can disrupt your video, plan to provide at least twice the capacity you need.  
•
Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most  
modern networks. Like video, however, streaming audio is also sensitive to latency and  
packet loss, so a congested network or a noisy link can cause problems.  
•
Backing up computers over the network has become popular due to the availability of  
inexpensive mass storage. The following table shows the time to transfer 1 gigabyte (GB)  
of data using various networking technologies.

Optimizing Your Network Bandwidth  
As your network grows, it might consist of several segments of different networking  
technologies, each providing different throughput. In planning your network, you should first  
consider which devices will have the heaviest traffic flow between them. Examples are:  
•
•
A media center in one room streaming high-definition video from a server in another room  
A storage device that is used for backing up your computers  
Next, consider the throughput of your network devices. Where possible, make the  
heaviest-traffic connections using higher-speed technologies, with no lower-speed  
bottlenecks in the path.

The previous figure shows a sample network using multiple networking technologies. In this  
network, the two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit connection  
through the GS605 switch to the storage server. This connection should allow for extremely  
fast backups or quick access to large files on the server. The PC connected through a pair of  
Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection.  
Although any of the links in this example would be sufficient for high-traffic applications such  
as streaming HD video, the use of older devices such as 10 Mbps Ethernet or 802.11b  
wireless would create a significant bottleneck.  
Optimizing Wireless Performance  
The speed and operating distance or range of your wireless connection can vary significantly  
based on the physical placement of the wireless router. You should choose a location for your  
router that will maximize the network speed.  
Note: Failure to follow these guidelines can result in significant  
performance degradation or inability to wirelessly connect to the  
router. For complete range and performance specifications, click the  
link to the online document Wireless Networking Basics in  
Appendix E.  
The following list describes how to optimize wireless router performance.  
•
Identify critical wireless links.  
If your network has several wireless devices, decide which wireless devices need the  
highest data rate, and locate the router near them. Many wireless products have  
automatic data-rate fallback, which allows increased distances without loss of  
connectivity. This also means that devices that are farther away might be slower.  
Therefore, the most critical links in your network are those where the traffic is high and  
the distances are great. Optimize those first.  
•
Choose placement carefully.  
For best results, place your router:  
-
-
Near the center of the area in which your computers will operate.  
In an elevated location such as a high shelf where the wirelessly connected  
computers have line-of-sight access (even if through walls).  
-
-
Avoid obstacles to wireless signals.  
Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets,  
refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.  
-
Keep away from large amounts of water such as fish tanks and water coolers.  
•
Reduce interference.  
Avoid windows unless communicating between buildings.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
-
Place wireless devices away from various electromagnetic noise sources, especially  
those in the 2400–2500 MHz frequency band. Common noise-creating sources are:  
•
•
•
Computers and fax machines (no closer than 1 foot)  
Copying machines, elevators, and cell phones (no closer than 6 feet)  
Microwave ovens (no closer than 10 feet)  
•
•
Choose your settings.  
-
Use a scanning utility to determine what other wireless networks are operating  
nearby, and choose an unused channel.  
-
Turn off SSID broadcast, and change the default SSID. Other nearby devices might  
automatically try to connect to your network several times a second, which can cause  
significant performance reduction.  
Use WMM to improve the performance of voice and video traffic over the wireless link.  
Changing the MTU Size  
The Maximum Transmission Unit (MTU) is the largest data packet a network device  
transmits. When one network device communicates across the Internet with another, the data  
packets travel through many devices along the way. If any device in the data path has a lower  
MTU setting than the other devices, the data packets must be split or “fragmented” to  
accommodate the one with the smallest MTU.  
The best MTU setting for NETGEAR equipment is often just the default value, and changing  
the value might fix one problem but cause another. Leave MTU unchanged unless one of  
these situations occurs:  
•
You have problems connecting to your ISP or other Internet service, and the technical  
support of either the ISP or NETGEAR recommends changing the MTU setting. These  
might require an MTU change:  
-
-
-
-
A secure website that won’t open, or displays only part of a Web page  
Yahoo e-mail  
MSN  
America Online’s DSL service  
•
•
You use VPN and have severe performance problems.  
You used a program to optimize MTU for performance reasons, and now you have  
connectivity or performance problems.  
Note: An incorrect MTU setting can cause Internet communication  
problems such as the inability to access certain Web sites, frames

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are  
willing to experiment, you can gradually reduce the MTU from the maximum value of 1500  
until the problem goes away. The following table describes common MTU sizes and  
applications.  
MTU  
Application  
1500  
The largest Ethernet packet size and the default value. This is the typical setting for  
non-PPPoE, non-VPN connections, and is the default value for NETGEAR routers,  
adapters, and switches.  
1492  
1472  
1468  
1460  
1436  
1400  
576  
Used in PPPoE environments.  
Maximum size to use for pinging. (Larger packets are fragmented.)  
Used in some DHCP environments.  
Usable by AOL if you do not have large e-mail attachments, for example.  
Used in PPTP environments or with VPN.  
Maximum size for AOL DSL.  
Typical value to connect to dial-up ISPs.  
To change the MTU size:  
1. In the main menu, select Advanced > WAN Setup.  
2. In the MTU Size field, enter a new size between 64 and 1500.  
3. Click Apply to save the new configuration.  
Universal Plug and Play  
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,  
to access the network and connect to other devices as needed. UPnP devices can  
automatically discover the services from other registered UPnP devices on the network.  
Note: If you use applications such as multiplayer gaming, peer-to-peer  
connections, real-time communications such as instant messaging,  
or remote assistance (a feature in Windows XP), you should enable  
UPnP.  
To turn on Universal Plug and Play:  
1. From the main menu, click Advanced > UPnP. The UPnP screen displays.

Figure 70.  
2. The available settings and information in this screen are:  
•
Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration.  
The default setting for UPnP is disabled. If this check box is not selected, the router  
does not allow any device to automatically control the resources, such as port  
forwarding (mapping) of the router.  
•
Advertisement Period. The advertisement period is how often the router broadcasts  
its UPnP information. This value can range from 1 to 1440 minutes. The default period  
is 30 minutes. Shorter durations ensure that control points have current device status  
at the expense of additional network traffic. Longer durations might compromise the  
freshness of the device status but can significantly reduce network traffic.  
•
•
Advertisement Time To Live. The time to live for the advertisement is measured in  
hops (steps) for each UPnP packet sent. The time to live hop count is the number of  
steps a broadcast packet is allowed to propagate for each UPnP advertisement  
before it disappears. The number of hops can range from 1 to 255. The default value  
for the advertisement time to live is 4 hops, which should be fine for most home  
networks. If you notice that some devices are not being updated or reached correctly,  
then it might be necessary to increase this value.  
UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each  
UPnP device that is currently accessing the router and which ports (Internal and  
External) that device has opened. The UPnP Portmap Table also displays what type  
of port is open and whether that port is still active for each IP address.

screen, you must add each wireless computer’s MAC address  
to the N300 wireless modem router’s access list.  
Make sure that the network settings of the  
computer are correct.  
• Wired and wirelessly connected computers must have network  
(IP) addresses on the same network as the router. The  
simplest way to ensure this is to configure each computer to  
obtain an IP address automatically using DHCP. Click the link  
to the online document Preparing Your Network in  
Appendix E, or see the documentation that came with your  
computer.  
• Some cable modem service providers require you to use the  
MAC address of the computer initially registered on the  
account. You can view the MAC address in the Attached  
Devices screen.

• Make sure that the power cord is correctly connected to your router and  
that the power supply adapter is correctly connected to a functioning  
power outlet.  
• Check that you are using the power adapter supplied by NETGEAR for  
this product.  
If the error persists, you have a hardware problem and should contact  
Technical Support.  
Power LED is red.  
If the Power LED remains red, there is a fault within the router.  
• Cycle the power to see if the router recovers.  
The power LED turns red when you • Clear the router’s configuration to factory defaults. This sets the router’s  
depress the Restore Factory  
Settings button, and blinks red 3  
times when that button is released.  
This is normal and does not indicate  
a problem.  
IP address to 192.168.0.1 or http://www.routerlogin.net. This procedure  
is explained in Restoring the Factory Configuration Settings on  
page 147.  
If the error persists, you might have a hardware problem and should  
contact Technical Support.  
LEDs never turn off.  
When the router is turned on, the LEDs turn on for about 10 seconds and  
then turn off. If all the LEDs stay on, there is a fault within the router.  
If all LEDs are still on 1 minute after power-up:  
• Cycle the power to see if the router recovers.  
• Clear the router’s configuration to factory defaults as explained in  
Restoring the Factory Configuration Settings on page 147.  
If the error persists, you might have a hardware problem and should  
contact Technical Support at www.netgear.com/support.  
ADSL Link LED is off.  
• Disconnect all telephones on the line. If this solves the problem,  
reconnect the telephones one at a time, being careful to use a microfilter  
on each telephone. If the microfilters are connected correctly, you should  
be able to connect all your telephones.  
• Check that the telephone company has made the connection to your line  
and tested it.  
• Verify that you are connected to the correct telephone line. If you have  
more than one phone line, be sure that you are connected to the line  
with the ADSL service. It might be necessary to use a swapper if your  
ADSL signal is on pins 1 and 4 of the RJ-11 jack. The N300 wireless  
modem router uses pins 2 and 3.

Situation  
The Ethernet port LEDs are off.  
Recommended Action  
If the Ethernet port LEDs do not light when the Ethernet connection is  
made, check the following:  
• Make sure that the Ethernet cable connections are secure at the N300  
wireless modem router and computer.  
• Make sure that power is turned on to the connected modem or  
computer.  
Wireless LEDs are off.  
If the Wireless LEDs do not come on, verify that the Enable Wireless Router  
Radio check box is selected on the Advanced Wireless Settings screen.  
See Configuring Advanced WPS Settings on page 27.  
Cannot Access the N300 Wireless Modem Router Menu  
If you are unable to access the router’s menu from a computer on your local network, check  
the following:  
•
If you are using an Ethernet-connected computer, check the Ethernet connection  
between the computer and the N300 wireless modem router.  
•
Make sure your computer’s IP address is on the same subnet as the router. If you are  
using the recommended addressing scheme, your computer’s address should be in the  
range of 192.168.0.2 to 192.168.0.254. Click the link to Preparing Your Network in  
Appendix E to find your computer’s IP address.  
•
If your computer’s IP address is shown as 169.254.x.x:, it might because recent versions  
of Windows and MacOS generate and assign an IP address if the computer cannot reach  
a DHCP server. These auto generated addresses are in the range of 169.254.x.x. If your  
IP address is in this range, check the connection from the computer to the router and  
reboot your computer.  
•
•
If your router’s IP address was changed and you do not know the current IP address,  
clear the router’s configuration to factory defaults. This sets the router’s IP address to  
192.168.0.1 or http://www.routerlogin.net. This procedure is explained in Restoring the  
Factory Configuration Settings on page 147.  
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using  
Internet Explorer, click Refresh to be sure the Java applet is loaded.  
•
•
Try quitting the browser and launching it again.  
Make sure that you are using the correct login information. The login name is admin and  
the default password is password. Make sure that Caps Lock is off when entering this

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
Cannot Access the Internet  
Note: If you are installing the N300 wireless modem router and have not  
yet configured the Internet connection, see Chapter 1, Router  
Internet Setup, or the N300 Wireless Dual Band ADSL2+ Modem  
Router Installation Guide.  
If your Internet connection was working previously, it is possible that this is due to a problem  
at your Internet Service Provider (ISP). If you can access your router but you are unable to  
access the Internet, you can check its configuration, and you can determine whether the  
router can obtain an IP address from your ISP.  
Checking the Configuration  
To check the router configuration to make sure that it is correct:  
1. Start your browser, and select an external site such as http://www.netgear.com.  
2. Access the main menu of the router at http://www.routerlogin.net.  
•
•
•
Select Basic Settings to view the Basic Settings screen.  
Select ADSL to view the Multiplexing method, VPI, and VCI settings.  
You can select Setup Wizard and allow the N300 wireless modem router to  
automatically detect your Internet connection.  
Checking the WAN IP Address  
Unless your ISP provides a fixed IP address, your router must request an IP address from  
the ISP. You can determine whether the request was successful using the Router Status  
screen.  
To check the WAN IP address:  
1. Start your browser, and select an external site such as http://www.netgear.com.  
2. Access the main menu of the router at http://www.routerlogin.net.  
3. Under Maintenance, select Router Status.  
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has  
not obtained an IP address from your ISP.  
If your router cannot obtain an IP address from the ISP, you might need to force your cable or  
DSL modem to recognize your new router by restarting your network, as described in Quick  
Tips on page 137.  
If your router is still unable to obtain an IP address from the ISP, the problem might be one of  
the following:

•
Your ISP might require a login program.  
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of  
login.  
•
•
If your ISP requires a login, the login name and password might be set incorrectly.  
Your ISP might check for your computer’s host name.  
Assign the computer host name of your ISP account as the account name in the Basic  
Settings screen.  
•
Your ISP allows only one Ethernet MAC address to connect to Internet and might check  
for your computer’s MAC address. In this case, do one of the following:  
-
Inform your ISP that you have bought a new network device, and ask them to use the  
router’s MAC address.  
-
Configure your router to spoof your computer’s MAC address.  
If your router can obtain an IP address, but your computer is unable to load any Web pages  
from the Internet:  
•
Your computer might not recognize any DNS server addresses.  
A DNS server is a host on the Internet that translates Internet names (such as www  
addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or  
two DNS servers for your use. If you entered a DNS address during the router’s  
configuration, reboot your computer, and verify the DNS address as described in the  
online document you can access from Preparing Your Network in Appendix E. You can  
also configure your computer manually with DNS addresses, as explained in your  
operating system documentation.  
•
•
Your computer might not have the router configured as its TCP/IP gateway.  
If your computer obtains its information from the router by DHCP, reboot the computer,  
and verify the gateway address as described in the online document you can access from  
Preparing Your Network in Appendix E.  
You might be running login software that is no longer needed.  
If your ISP provided a program to log you in to the Internet (such as WinPoET), you no  
longer need to run that software after installing your N300 wireless modem router. You  
might need to go to Internet Explorer and select Tools > Internet Options, click the  
Connections tab, and select Never dial a connection.  
Troubleshooting a Network Using the Ping Utility  
Most network devices and routers contain a ping utility that sends an echo request packet to  
the designated device. The device then responds with an echo reply. You can easily  
troubleshoot a network by using the ping utility in your computer or workstation.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
Testing the LAN Path to Your Router  
You can ping the router from your computer to verify that the LAN path to your router is set up  
correctly.  
To ping the router from a running Windows PC:  
1. From the Windows toolbar, click the Start button, and then select Run.  
2. In the field provided, type ping followed by the IP address of the router, as in this example:  
ping www.routerlogin.net  
3. Click OK.  
You should see a message like this one:  
Pinging <IP address > with 32 bytes of data  
If the path is working, you see this message:  
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx  
If the path is not working, you see this message:  
Request timed out  
If the path is not functioning correctly, you could have one of the following problems:  
•
Wrong physical connections  
-
For a wired connection, make sure the numbered Ethernet port LED is on for the  
port to which you are connected. If the LED is off, follow the instructions in Quick  
Tips on page 137.  
-
Check that the corresponding Link LEDs are on for your network interface card. If  
your router and computer are connected to a separate Ethernet switch, make sure  
the Link LEDs are on for the switch ports that are connected to your computer and  
router.  
•
Wrong network configuration  
-
Verify that the Ethernet card driver software and TCP/IP software are both  
installed and configured on your computer.  
-
Verify that the IP address for your router and your computer are correct and that  
the addresses are on the same subnet.  
Testing the Path from Your Computer to a Remote Device  
After verifying that the LAN path works correctly, test the path from your computer to a remote  
device.  
1. From the Windows toolbar, click the Start button, and then select Run.  
2. In the Windows Run window, type:  
ping -n 10 <IP address>  
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
If the path is functioning correctly, replies like those shown in the previous section are  
displayed. If you do not receive replies:  
•
Check that your computer has the IP address of your router listed as the default gateway.  
If the IP configuration of your computer is assigned by DHCP, this information is not  
visible in your computer’s Network Control Panel. Verify that the IP address of the router  
is listed as the default gateway as described in the online document you can access from  
Preparing Your Network in Appendix E.  
•
Check to see that the network address of your computer (the portion of the IP address  
specified by the subnet mask) is different from the network address of the remote device.  
•
•
Check that your cable or DSL modem is connected and functioning.  
If your ISP assigned a host name to your computer, enter that host name as the account  
name in the Basic Settings screen.  
•
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.  
Many broadband ISPs restrict access by allowing traffic only from the MAC address of  
your broadband modem, but some ISPs additionally restrict access to the MAC address  
of a single computer connected to that modem. If this is the case, you must configure  
your router to “clone” or “spoof” the MAC address from the authorized computer.  
Problems with Date and Time  
Under Security in the main menu, select Schedule to view the current date and time of day.  
The N300 wireless modem router uses the Network Time Protocol (NTP) to obtain the current  
time from one of several network time servers on the Internet. Each entry in the log is  
stamped with the date and time of day. Problems with the date and time function can include  
the following:  
•
Date shown is January 1, 2000.  
Cause: The N300 wireless modem router has not yet successfully reached a Network  
Time Server. Check that your Internet access is configured correctly. If you have just  
completed configuring the N300 wireless modem router, wait at least 5 minutes, and  
check the date and time again.  
•

Using a Fully Qualified Domain Name (FQDN)  
Many ISPs provide connectivity to their customers using dynamic instead of static IP  
addressing. This means that a user’s IP address does not remain constant over time, which  
presents a challenge for gateways attempting to establish VPN connectivity.  
A Dynamic DNS (DDNS) service allows a user whose public IP address is dynamically  
assigned to be located by a host or domain name. It provides a central public database where  
information (such as email addresses, host names, and IP addresses) can be stored and  
retrieved. Now, a gateway can be configured to use a third-party service instead of a  
permanent and unchanging IP address to establish bidirectional VPN connectivity.  
To use DDNS, you must register with a DDNS service provider. Some DDNS service  
providers include:  
•
•
•
DynDNS: www.dyndns.org  
TZO.com: netgear.tzo.com  
ngDDNS: ngddns.iego.net  
In this example, Gateway A is configured using a sample FQDN provided by a DDNS service  
provider. In this case we established the hostname dgnd3300v2.dyndns.org for Gateway A  
using the DynDNS service. Gateway B uses the DDNS service provider when establishing a  
VPN tunnel.

N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual  
To establish VPN connectivity, Gateway A must be configured to use Dynamic DNS, and  
Gateway B must be configured to use a DNS host name provided by a DDNS service  
provider to find Gateway A. Again, the following step-by-step procedures assume that you  
have already registered with a DDNS service provider and have the configuration information  
necessary to set up the gateways.
