Position Your Wireless Router  
The wireless modem router lets you access your network from anywhere within the operating  
range of your wireless network. However, the operating distance or range of your wireless  
connection can vary significantly depending on the physical placement of your router. For  
example, the thickness and number of walls the wireless signal passes through can limit the  
range. For best results, place your router:  
•
Near the center of the area where your computers and other devices operate, and  
preferably within line of sight to your wireless devices.  
•
•
So it is accessible to an AC power outlet and near Ethernet cables for wired computers.  
In an elevated location such as a high shelf, keeping the number of walls and ceilings  
between the wireless modem router and your other devices to a minimum.  
•
•
Away from electrical devices that are potential sources of interference, such as ceiling  
fans, home security systems, microwaves, computers, or the base of a cordless phone or  
2.4 GHz cordless phone.  
Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large  
expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and  
concrete can also affect your wireless signal.  
Note: The DGND4000 should be put in a vertical position only.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
Also be aware that when you use 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 five channels (for example, use Channels 1 and  
6, or 6 and 11).  
ADSL Microfilters  
If this is the first time you have cabled a wireless router between an ADSL phone line and  
your computer or laptop, you might not be familiar with ADSL microfilters. If you are, you can  
skip this section and proceed to Cable Your N750 Wireless Modem Router on page 19.  
An ADSL microfilter is a small inline device that filters ADSL interference out of standard  
phone equipment that shares line with your ADSL service. Every telephone device that  
connects to a telephone line that provides ADSL service needs an ADSL microfilter to filter  
out the ADSL interference. Example devices are telephones, fax machines, answering  
machines, and caller ID displays. Not every phone line in your home necessarily carries  
ADSL service. That depends on the ADSL service setup in your home.  
Note: Often the ADSL microfilter is included in the box with the wireless  
modem router. If you purchased the wireless modem router in a  
country where a microfilter is not included, you have to acquire the  
ADSL microfilter separately.  
One-Line ADSL Microfilter (Not Included)  
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack  
labeled Phone. The wireless modem router plugs directly into a separate ADSL line. Plugging  
the wireless modem router into the phone jack blocks the Internet connection. If you do not  
have a separate ADSL line for the router, the best thing to do is to use an ADSL microfilter  
with a built-in splitter.  
Plugs into ADSL line  
Figure 5. One-line ADSL microfilter  
Second best when you do not have a separate ADSL line for the router is to get a separate  
splitter. To use a one-line filter with a separate splitter, insert the splitter into the phone outlet,  
connect the one-line filter to the splitter, and connect the phone to the filter.

Two-Line ADSL Microfilter (Included)  
Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides  
connectivity for both the wireless modem router and your telephone equipment. Plug the  
ADSL microfilter into the wall outlet, plug your phone equipment into the jack labeled Phone,  
and plug the wireless modem router into the jack labeled ADSL.

Prepare to Set Up the Wireless Modem Router  
You can set up your wireless modem router with the NETGEAR genie automatically, or you  
can use the genie menus and screens to set up your wireless modem router manually.  
However, before you start the setup process, you need to have your ISP information on hand  
and make sure the laptops, computers, and other devices in the network have the settings  
described here.  
Use Standard TCP/IP Properties for DHCP  
If you set up your computer to use a static IP address, you need to change the settings so  
that it uses Dynamic Host Configuration Protocol (DHCP).  
Gather ISP Information  
If you have DSL broadband service, you might need the following information to set up your  
wireless modem router and to check that your Internet configuration is correct. Your Internet  
service provider (ISP) should have provided you with all of the information needed to connect  
to the Internet. If you cannot locate this information, ask your ISP to provide it. When your  
Internet connection is working, you no longer need to launch the ISP’s login program on your  
computer to access the Internet. When you start an Internet application, your wireless  
modem router automatically logs you in.

If this is the first time you are setting up the Internet connection for your wireless  
modem router, the browser automatically goes to http://www.routerlogin.net, and the  
NETGEAR genie screen displays.  
•
If you already used the NETGEAR genie, type http://www.routerlogin.net in the  
address field for your browser to display the NETGEAR genie screen. See Use  
NETGEAR genie after Installation on page 24.  
4. Follow the onscreen instructions to complete NETGEAR genie setup. NETGEAR genie  
guides you through connecting the wireless modem router to the Internet.  
If the browser cannot display the web page:  
•
Make sure that the computer is connected to one of the four-Gigabit Ethernet LAN ports,  
or wirelessly to the wireless modem router.  
•
•
Make sure that the wireless modem router is ready. Its Wireless LEDs should light.  
Close and reopen the browser to make sure that the browser does not cache the  
previous page.  
•
•
Browse to http://routerlogin.net.  
If your computer is set to a static or fixed IP address (this is uncommon), change the  
setting to obtain an IP address automatically from the wireless modem router.  
If the wireless modem router does not connect to the Internet:  
1. Review your settings to be sure that you selected the correct options and typed  
everything correctly.  
2. Contact your ISP to verify that you have the correct configuration information.

modem router. The wireless software scans for all wireless networks in your area.  
2. Look for your network and select it. If you did not change the name of your network during  
the setup process, look for the default WiFi network name (SSID) and select it. The default  
SSID is located on the product label on the bottom of the wireless modem router.  
3. Enter the wireless modem router password and click Connect. The default wireless modem  
router passphrase is located on the product label on the bottom of the wireless modem  
router.  
4. Repeat steps 1–3 to add other wireless devices.  
Wi-Fi Protected Setup (WPS) Method  
Wi-Fi Protected Setup (WPS) is a standard for easily adding computers and other devices to  
a home network while maintaining security. To use WPS, make sure that all wireless devices  
to be connected to the network are Wi-Fi certified and support WPS. During the connection  
process, the client gets the security settings from the wireless modem router so that every  
device in the network has the same security settings.  
If your wireless device supports WPS (Push 'N' Connect), use the following procedure.

the bottom of your wireless modem router.  
Wireless Settings Screen Fields  
Region. The location where the wireless modem router is used. Select from the countries in  
the list. In the United States, the region is fixed to United States and is not changeable.  
Wireless Network  
Note: These settings apply separately to the 2.4 GHz b/g/n and 5 GHz a/n  
bands.  
Name (SSID). The SSID is also known as the wireless network name. Enter a 32-character  
(maximum) name in this field. This field is case-sensitive. The default SSID is randomly  
generated, and NETGEAR strongly recommends that you do not change this.  
Channel. This setting is the wireless channel used by the gateway. Enter a value from 1  
through 13. For products in the North America market, only Channels 1 through 11 can be  
operated. Do not change the channel unless you experience interference (when indicated by  
lost connections or slow data transfers). If this interference happens, experiment with  
different channels to see which is the best.  
Mode. Up to 130 Mbps is the default and allows 802.11n and 802.11g wireless devices to join  
the network. g & b supports up to 54 Mbps. The 300 Mbps setting allows 802.11n devices to  
connect at this speed.

Note: These settings apply separately to the 2.4 GHz b/g/n and 5 GHz a/n  
bands.  
Enable Guest Network. When this check box is selected, the guest network is enabled,  
and guests can connect to your network using the SSID of this profile.  
Enable SSID Broadcast. If this check box is selected, the wireless access point  
broadcasts its name (SSID) to all wireless stations. Stations with no SSID can adopt the  
correct SSID for connections to this access point.  
Allow guest to access My Local Network. If this check box is selected, any user who  
connects to the network with this SSID has access to your local network, not just Internet  
access.  
Enable Wireless Isolation. If this check box is selected, then wireless clients (computers  
or wireless devices) that join the network can use the Internet, but cannot access each  
other or access Ethernet devices on the network.  
3. Give the guest network a name.  
The guest network name is case-sensitive and can be up to 32 characters. You then  
manually configure the wireless devices in your network to use the guest network name  
in addition to the main nonguest SSID.  
4. Select a security option from the list. The security options are described in Guest Network  
Wireless Security Options on page 39.  
5. Click Apply to save your selections.  
Guest Network Wireless Security Options  
A security option is the type of security protocol applied to your wireless network. The  
security protocol in force encrypts data transmissions and ensures that only trusted devices  
receive authorization to connect to your network.  
This section presents an overview of the security options and provides guidance on when to  
use which option. It is also possible to set up a guest network without wireless security.  
NETGEAR does not recommend using no security on a wireless network.  
Wi-Fi Protected Access (WPA) encryption is built into all hardware that has the Wi-Fi-certified  
seal. This seal means that the product is authorized by the Wi-Fi Alliance  
(http://www.wi-fi.org/) because it complies with the worldwide single standard for high-speed  
wireless local area networking.  
WPA-PSK uses a passphrase to authenticate and generate the initial data encryption keys.  
Then it dynamically varies the encryption key. WPA-PSK uses Temporal Key Integrity  
Protocol (TKIP) data encryption, implements most of the IEEE 802.11i standard, and is  
designed to work with all wireless network interface cards, but not all wireless access points.  
It is superseded by WPA2-PSK.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
WPA2-PSK is stronger than WPA. It is advertised to be indecipherable due to the greater  
degree of randomness in encryption keys that it generates. WPA2-PSK gets higher speed  
because it is implemented through hardware, while WPA-PSK is implemented through  
software. WPA2-PSK uses a passphrase to authenticate and generate the initial data  
encryption keys. Then it dynamically varies the encryption key.  
WPS-PSK + WPA2-PSK Mixed Mode can provide broader support for all wireless clients.  
WPA2-PSK clients get higher speed and security, and WPA-PSK clients get decent speed  
and security. The product documentation for your wireless adapter and WPA client software  
should have instructions about configuring their WPA settings.

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 change is rarely required, and should  
not be done unless you are sure that it is necessary for your ISP connection. See  
Change the MTU Size on page 51.

NAT Filtering. Network Address Translation (NAT) determines how the wireless  
modem router processes inbound traffic. Secured NAT provides a secured firewall to  
protect the computers on the LAN from attacks from the Internet, but might prevent  
some Internet games, point-to-point applications, or multimedia applications from  
functioning. Open NAT provides a much less secured firewall, but allows almost all  
Internet applications to function.  
-
Disable SIP ALG. Some VoIP applications do not work well with the SIP ALG.  
Enabling this option to turn off the SIP ALG might help your VoIP devices to  
create or accept a call through the router.  
Default DMZ Server  
The default DMZ server feature is helpful when you are using some online games and  
videoconferencing applications that are incompatible with Network Address Translation  
(NAT). The 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 discarded by the 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/Port Triggering screen. Instead of discarding this traffic, you can forward it to one  
computer on your network. This computer is called the default DMZ server.  
To set up a default DMZ server:  
1. On the WAN Setup screen, select the Default DMZ Server check box.  
2. Type the IP address.  
3. Click Apply.  
Change 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 have to be split or “fragmented” to  
accommodate the device 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 the 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  
web-based applications might require an MTU change:  
-
-
-
-
A secure website that does not open, or displays only part of a web page  
Yahoo email  
MSN portal  
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 websites, frames within  
websites, secure login pages, or FTP or POP servers.  
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.

LAN Setup  
The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host  
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).  
The wireless modem router is shipped preconfigured to use private IP addresses on the LAN  
side and to act as a DHCP server. The 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 requires a different IP  
addressing scheme, make those changes in the LAN Setup screen.  
To change the LAN settings:  
Note: If you change the LAN IP address of the wireless modem router while  
connected through the browser, you are disconnected. You have to  
open a new connection to the new IP address and log in again.  
1. Select ADVANCED > Setup > LAN Setup.  
2. Enter the settings that you want to customize.

LAN TCP/IP Setup  
•
IP Address. The LAN IP address of the wireless modem router.  
•
IP Subnet Mask. The LAN subnet mask of the 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 have to be reached through a gateway or wireless modem router.  
•
•
RIP Direction. Router Information Protocol (RIP) allows a router to exchange routing  
information with other routers. This setting controls how the router sends and receives  
RIP packets. Both is the default setting. With the Both or Out Only setting, the router  
broadcasts its routing table periodically. With the Both or In Only setting, the router  
incorporates the RIP information that it receives.  
RIP Version. This setting controls the format and the broadcasting method of the RIP  
packets that the wireless modem router sends. It recognizes both formats when  
receiving. By default, the RIP function is disabled.  
-
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.  
Use Router as a DHCP Server  
This check box is selected so that the wireless modem router functions as a Dynamic Host  
Configuration Protocol (DHCP) server.  
•
Starting IP Address. Specify the start of the range for the pool of IP addresses in the  
same subnet as the wireless modem router.  
•
Ending IP Address. Specify the end of the range for the pool of IP addresses in the  
same subnet as the 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 wireless modem router’s DHCP server.  
Assign reserved IP addresses to servers that require permanent IP settings.  
Use the Wireless Modem Router as a DHCP Server  
By default, the 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 wireless  
modem router’s LAN. The assigned default gateway address is the LAN address of the  
wireless modem router. The wireless modem router assigns IP addresses to the attached

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
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 wireless modem router are satisfactory.  
You can 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 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 want to  
save part of the range for devices with fixed addresses.  
The 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 wireless modem router’s LAN IP address)  
Primary DNS server (if you entered a primary DNS address in the Internet Basic Settings  
screen; otherwise, the wireless modem router’s LAN IP address)  
•
Secondary DNS server (if you entered a secondary DNS address in the Internet 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  
and click Apply. Otherwise, leave this check box selected. If this service is not enabled and  
no other DHCP server is available on your network, you need to set your computers’ IP  
addresses manually or they are not able to access the 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 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. In the Address Reservation section of the screen, click the Add button.  
2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an  
IP address from the 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 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.  
The reserved address is not assigned until the next time the computer contacts the  
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, select the radio button next to the reserved  
address you want to edit or delete. Then click Edit or Delete.  
Quality of Service Setup  
Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of  
traffic ahead of others. The N750 Modem Router can provide QoS prioritization over the  
wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen.  
Select ADVANCED > Setup > QoS Setup.  
Enable WMM QoS for Wireless Multimedia Applications  
The N750 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 have to have 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.

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 Windows, Mac, or Linux file type including text, Word,  
PowerPoint, Excel, and MP3 files, pictures, and multimedia. USB drive applications include:  
•
Sharing multimedia such as MP3 files, pictures, and other multimedia with local and  
remote users.  
•
Sharing resources on your network. You might want to store files in a central location so  
that you do not need to power up a computer to perform local sharing. In addition, you  
can share files between Macintosh, Linux, and Windows computers by using the USB  
drive as a go-between across the systems.  
•
Sharing files such as Word documents, PowerPoint presentations, and text files with  
remote users.  
A few common uses are described in the following sections.  
Share Photos  
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 your USB drive into the USB port on the wireless modem router 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 USB  
Storage Advanced Settings on page 66.  
Store Files in a Central Location for Printing  
This scenario is for a family that has one high-quality color printer directly attached to a  
computer, but not shared on the local area network (LAN). This family does not have a print  
server.  
•
•
One family member has photos on a Macintosh computer that she wants to print.  
The photo-capable color printer is directly attached to a computer, but not shared on the  
network.  
•
The Mac and Windows computer are not visible to each other on the network.  
To print photos from a Mac on the printer attached to a Windows computer:  
1. On the Mac, access the USB drive by typing \\readyshare in the address field of a web  
browser. Then copy the photos to the USB drive.  
2. On the Windows computer, use a web browser or Microsoft Networking to copy the files  
from the USB drive to the Windows computer. Then print the files.

Share Large Files over the Internet  
Sending files that are larger than 5 MB can pose a problem for many email systems. The  
wireless modem router allows you to share large files such as PowerPoint presentations or  
.zip files over the Internet. FTP can be used to easily download shared files from the wireless  
modem router.  
Sharing files with a remote colleague involves the following considerations:  
•
There are two user accounts: admin and guest. The password for admin is the same one  
that you use to access the wireless modem router. By default, it is password. The guest  
user account has no password.  
•
•
On the FTP site, the person receiving the files should use the guest user account and  
enter any password (FTP requires that you type something in the password field).  
Be sure to select the FTP (via Internet) check box in the USB Storage (Advanced  
Settings) screen. This option supports both downloading and uploading of files.

Firewall Rules  
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 the Internet sends  
a request for service to a server computer, 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 the destination port number 80 is an HTTP  
(web server) request.  
The service numbers for many common protocols are defined by the Internet Engineering  
Task Force (IETF at http://www.ietf.org/) and published in RFC1700, “Assigned Numbers.”  
Service numbers for other applications are typically chosen from the range 1024–65535 by  
the authors of the application. Although the wireless modem router already holds a list of  
many service port numbers, you are not limited to these choices. You can often determine  
port number information by contacting the publisher of the application, by asking user groups  
or newsgroups, or by searching.  
The Firewall Rules screen lets you block or allow specific Internet traffic services by  
computers on your network. This process is called service blocking or port filtering.  
Note: This feature is for advanced administrators only. Incorrect  
configuration can cause serious problems.  
To create firewall rules:

The Firewall Rules screen lists all firewall rules that have been changed from their default  
settings. The default rules allow all outgoing traffic and block all incoming traffic.  
•
To change the firewall rules for outbound traffic, you need to edit them from the  
Outbound Services screen as described in Step 2.  
•
To change the firewall rules for inbound traffic, you need to edit them from the Port  
Forwarding/Port Triggering screen as described in Port Forwarding and Triggering on

Diagnostics  
You can perform various diagnostics. For normal operation, these tests are not required.  
To perform diagnostic tests:  
1. Select ADVANCED > Administration > Diagnostics.  
2. Perform the following diagnostics as needed:  
•
Ping an IP address or Host Name. Use this test to send a ping packet request to the  
specified IP address or host name. This test is often used to test a connection. If the  
request times out (in other words, no reply is received), this result usually means that  
the destination is unreachable. Note, however, that some network devices can be  
configured not to respond to a ping.  
•
•
Perform a DNS Lookup. A DNS (Domain Name Server) converts the Internet name  
(for example, www.netgear.com) to an IP address. If you need the IP address of a  
web, FTP, mail, or other server on the Internet, do a DNS lookup to find the IP  
address.  
Display the Routing Table. This operation displays the internal routing table.

Wireless Repeating Function (WDS)  
You can set the N750 Modem Router up to be used as a wireless access point (AP). Doing  
this setup enables the wireless modem router to act as a wireless repeater. A wireless  
repeater connects to another wireless wireless modem router as a client where the network  
to which it connects becomes the ISP service.  
Wireless repeating is a type of Wireless Distribution System (WDS). A WDS allows a wireless  
network to be expanded through multiple access points instead of using a wired backbone to  
link them. The following figure shows a wireless repeating scenario.

Note: If you use the wireless repeating function, you need to select either  
WEP or None as a security option in the Wireless Settings screen.  
The WEP option displays only if you select the wireless mode Up to  
54 Mbps in the Wireless Settings screen.  
Wireless Base Station. The wireless modem router acts as the parent access point,  
bridging traffic to and from the child repeater access point, as well as handling wireless and  
wired local computers. To configure this mode, you have to know the MAC address of the  
child repeater access point.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
Wireless Repeater. The wireless modem router sends all traffic from its local wireless or  
wired computers to a remote access point. To configure this mode, you have to know the  
MAC address of the remote parent access point.  
The DGND4000 wireless modem router is always in dual-band concurrent mode, unless you  
turn off one radio. If you enable the wireless repeater in either radio band, the wireless base  
station or wireless repeater cannot be enabled in the other radio band. However, if you  
enable the wireless base station in either radio band and use the other radio band as a  
wireless wireless modem router or wireless base station, dual-band concurrent mode is not  
affected.  
For you to set up a wireless network with WDS, the following conditions have to be met for  
both access points:  
•
•
Both access points have to use the same SSID, wireless channel, and encryption mode.  
Both access points have to be on the same LAN IP subnet. That is, all the access point  
LAN IP addresses are in the same network.  
•
All LAN devices (wired and wireless computers) have to be configured to operate in the  
same LAN network address range as the access points.  
Wireless Repeating Function  
1. Select ADVANCED > Advanced Setup > Wireless Repeating Function.  
2. To view or change wireless repeater settings for the wireless modem router  
a. Enable Wireless Repeating Function. Select the check box for the 2.4 GHz or

5. Verify connectivity across the LANs.  
A computer on any wireless or wired LAN segment of the wireless modem router can  
connect to the Internet or share files and printers with any other wireless or wired  
computer or server connected to the other access point.  
Port Forwarding and Triggering  
By default, the wireless modem router blocks inbound traffic from the Internet to your  
computers except replies to your outbound traffic. You might need to create exceptions to  
this rule for these purposes:  
•
•
To allow remote computers on the Internet to access a server on your local network.  
To allow certain applications and games to work correctly when their replies are not  
recognized by your wireless modem router.  
Your wireless modem router provides two features for creating these exceptions: port  
forwarding and port triggering. The next sections provide background information to help you  
understand how port forwarding and port triggering work, and the differences between the  
two.  
Remote Computer Access Basics  
When a computer on your network needs to access a computer on the Internet, your  
computer sends your wireless modem router a message containing the source and  
destination address and process information. Before forwarding your message to the remote  
computer, your wireless modem router has to modify the source information and create and  
track the communication session so that replies can be routed back to your computer.  
Here is an example of normal outbound traffic and the resulting inbound responses:  
1. You open a browser, and your operating system assigns port number 5678 to this  
browser session.  
2. You type http://www.example.com into the URL field, and your computer creates a web  
page request message with the following address and port information. The request  
message is sent to your wireless modem router.  
Source address. Your computer’s IP address.  
Source port number. 5678, which is the browser session.  
Destination address. The IP address of www.example.com, which your computer finds  
by asking a DNS server.  
Destination port number. 80, which is the standard port number for a web server  
process.  
3. Your wireless modem router creates an entry in its internal session table describing this  
communication session between your computer and the web server at www.example.com.  
Before sending the web page request message to www.example.com, your wireless  
Advanced Settings  
109

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
modem router stores the original information and then modifies the source information in the  
request message, performing Network Address Translation (NAT):  
•
The source address is replaced with your wireless modem router’s public IP address.  
This requirement is necessary because your computer uses a private IP address that  
is not globally unique and cannot be used on the Internet.  
•
The source port number is changed to a number chosen by the wireless modem  
router, such as 33333. This requirement is necessary because two computers could  
independently be using the same session number.  
Your wireless modem router then sends this request message through the Internet to the  
web server at www.example.com.  
4. The web server at www.example.com composes a return message with the requested web  
page data. The return message contains the following address and port information. The  
web server then sends this reply message to your wireless modem router.  
Source address. The IP address of www.example.com.  
Source port number. 80, which is the standard port number for a web server process.  
Destination address. The public IP address of your wireless modem router.  
Destination port number. 33333.  
5. Upon receiving the incoming message, your wireless modem router checks its session  
table to determine whether there is an active session for port number 33333. Finding an  
active session, the wireless modem router then modifies the message to restore the original  
address information replaced by NAT. Your wireless modem router sends this reply  
message to your computer, which displays the web page from www.example.com. The  
message now contains the following address and port information.  
Source address. The IP address of www.example.com.  
Source port number. 80, which is the standard port number for a web server process.  
Destination address. Your computer’s IP address.  
Destination port number. 5678, which is the browser session that made the initial  
request.  
6. When you finish your browser session, your wireless modem router eventually detects a  
period of inactivity in the communications. Your wireless modem router then removes the  
session information from its session table, and incoming traffic is no longer accepted on port  
number 33333.  
Port Triggering to Open Incoming Ports  
In the preceding example, requests are sent to a remote computer by your wireless modem  
router from a particular service port number, and replies from the remote computer to your  
wireless modem router are directed to that port number. If the remote server sends a reply to  
a different port number, your wireless modem router does not recognize it and discards it.  
However, some application servers (such as FTP and IRC servers) send replies to multiple  
port numbers. Using the port triggering function of your wireless modem router, you can tell  
Advanced Settings  
110  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
the wireless modem router to open additional incoming ports when a particular outgoing port  
originates a session.  
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at  
destination port 6667. The IRC server not only responds to your originating source port, but  
also sends an “identify” message to your computer on port 113. Using port triggering, you can  
tell the wireless modem router, “When you initiate a session with destination port 6667, you  
have to also allow incoming traffic on port 113 to reach the originating computer.” Using steps  
similar to the preceding example, the following sequence shows the effects of the port  
triggering rule you have defined:  
1. You open an IRC client program to start a chat session on your computer.  
2. Your IRC client composes a request message to an IRC server using a destination port  
number of 6667, the standard port number for an IRC server process. Your computer then  
sends this request message to your wireless modem router.  
3. Your wireless modem router creates an entry in its internal session table describing this  
communication session between your computer and the IRC server. Your wireless modem  
router stores the original information, performs Network Address Translation (NAT) on the  
source address and port, and sends this request message through the Internet to the IRC  
server.  
4. Noting your port triggering rule and having observed the destination port number of 6667,  
your wireless modem router creates an additional session entry to send any incoming port  
113 traffic to your computer.  
5. The IRC server sends a return message to your wireless modem router using the  
NAT-assigned source port (as in the previous example, say port 33333) as the destination  
port. The IRC server also sends an identify message to your wireless modem router with  
destination port 113.  
6. Upon receiving the incoming message to destination port 33333, your wireless modem  
router checks its session table to determine whether there is an active session for port  
number 33333. Finding an active session, the wireless modem router restores the original  
address information replaced by NAT and sends this reply message to your computer.  
7. Upon receiving the incoming message to destination port 113, your wireless modem router  
checks its session table and learns that there is an active session for port 113 associated  
with your computer. The wireless modem router replaces the message’s destination IP  
address with your computer’s IP address and forwards the message to your computer.  
8. When you finish your chat session, your wireless modem router eventually senses a period  
of inactivity in the communications. The wireless modem router then removes the session  
information from its session table, and incoming traffic is no longer accepted on port  
numbers 33333 or 113.  
To configure port triggering, you need to know which inbound ports the application needs.  
Also, you need to know the number of the outbound port that triggers the opening of the  
inbound ports. You can usually determine this information by contacting the publisher of the  
application or user groups or newsgroups.  
Note: Only one computer at a time can use the triggered application.

Port Forwarding to Permit External Host Communications  
In both of the preceding examples, your computer initiates an application session with a  
server computer on the Internet. However, you might need to allow a client computer on the  
Internet to initiate a connection to a server computer on your network. Normally, your wireless  
modem router ignores any inbound traffic that is not a response to your own outbound traffic.  
You can configure exceptions to this default rule by using the port forwarding feature.  
A typical application of port forwarding can be shown by reversing the client-server  
relationship from the previous web server example. In this case, a remote computer’s  
browser needs to access a web server running on a computer in your local network. Using  
port forwarding, you can tell the wireless modem router, “When you receive incoming traffic  
on port 80 (the standard port number for a web server process), forward it to the local  
computer at 192.168.1.123.” The following sequence shows the effects of the port forwarding  
rule you have defined:  
1. The user of a remote computer opens a browser and requests a web page from  
www.example.com, which resolves to the public IP address of your wireless modem  
router. The remote computer composes a web page request message with the following  
destination information:  
Destination address. The IP address of www.example.com, which is the address of your  
wireless modem router.  
Destination port number. 80, which is the standard port number for a web server  
process.  
The remote computer then sends this request message through the Internet to your  
wireless modem router.  
2. Your wireless modem router receives the request message and looks in its rules table for  
any rules covering the disposition of incoming port 80 traffic. Your port forwarding rule  
specifies that incoming port 80 traffic should be forwarded to local IP address 192.168.1.123.  
Therefore, your wireless modem router modifies the destination information in the request  
message:  
The destination address is replaced with 192.168.1.123.  
Your wireless modem router then sends this request message to your local network.  
3. Your web server at 192.168.1.123 receives the request and composes a return message  
with the requested web page data. Your web server then sends this reply message to your  
wireless modem router.  
4. Your wireless modem router performs Network Address Translation (NAT) on the source IP  
address, and sends this request message through the Internet to the remote computer,  
which displays the web page from www.example.com.  
To configure port forwarding, you need to know which inbound ports the application needs.  
Usually you can determine this information by contacting the publisher of the application or  
the relevant user groups and newsgroups.

How Port Forwarding Differs from Port Triggering  
The following points summarize the differences between port forwarding and port triggering:  
•
Port triggering can be used by any computer on your network, although only one  
computer can use it at a time.

Port forwarding is configured for a single computer on your network.  
Port triggering requires that you know the computer’s IP address in advance. The IP  
address is captured automatically.  
•
•
•
Port forwarding requires that you specify the computer’s IP address during configuration,  
and the IP address can never change.  
Port triggering requires specific outbound traffic to open the inbound ports, and the  
triggered ports are closed after a period of no activity.  
Port forwarding is always active and does not need to be triggered.  
Set Up Port Forwarding to Local Servers  
Using the port forwarding feature, you can allow certain types of incoming traffic to reach  
servers on your local network. For example, you might want to make a local web server, FTP  
server, or game server visible and available to the Internet.  
Use the Port Forwarding/Port Triggering screen to configure the wireless modem router to  
forward specific incoming protocols to computers on your local network. In addition to servers  
for specific applications, you can also specify a default DMZ server to which all other  
incoming protocols are forwarded.  
Before starting, you need to determine which type of service, application, or game you want  
to provide, and the local IP address of the computer that provides the service. The server  
computer has to always have the same IP address.  
To set up port forwarding:  
Tip: To ensure that your server computer always has the same IP  
address, use the reserved IP address feature of your N750 Modem  
Router.

Application Example: Making a Local Web Server Public  
If you host a web server on your local network, you can use port forwarding to allow web  
requests from anyone on the Internet to reach your web server.  
To make a local web server public:  
1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP  
address reservation. In this example, your wireless modem router always gives your  
web server an IP address of 192.168.1.33.  
2. In the Port Forwarding/Port Triggering screen, configure the wireless modem router to  
forward the HTTP service to the local address of your web server at 192.168.1.33. HTTP  
(port 80) is the standard protocol for web servers.  
3. (Optional) Register a host name with a Dynamic DNS service, and configure your wireless  
modem router to use the name as described in Dynamic DNS on page 118. To access your  
web server from the Internet, a remote user has to know the IP address assigned by your  
ISP. However, if you use a Dynamic DNS service, the remote user can reach your server by  
a user-friendly Internet name, such as mynetgear.dyndns.org.  
Set Up Port Triggering  
Port triggering is a dynamic extension of port forwarding that is useful in these cases:  
•
More than one local computer needs port forwarding for the same application (but not  
simultaneously).  
•
An application needs to open incoming ports that are different from the outgoing port.  
When port triggering is enabled, the wireless modem router monitors outbound traffic looking  
for a specified outbound “trigger” port. When the wireless modem router detects outbound  
traffic on that port, it remembers the IP address of the local computer that sent the data. The  
wireless modem router then temporarily opens the specified incoming port or ports, and  
forwards incoming traffic on the triggered ports to the triggering computer.  
Port forwarding creates a static mapping of a port number or range to a single local computer.  
Port triggering dynamically opens ports to any computer that needs them and can close the  
ports when they are no longer needed.  
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 also enable  
Universal Plug and Play (UPnP) according to the instructions in  
Universal Plug and Play on page 123.  
To set up port triggering, you need to know which inbound ports the application needs. Also,  
you need to know the number of the outbound port that triggers the opening of the inbound  
ports. You can usually determine this information by contacting the publisher of the  
application or user groups or newsgroups.

configuration information you added to the wireless modem router is  
retained even though it is not used.  
4. In the Port Triggering Timeout field, enter a value up to 9999 minutes.  
This value controls the inactivity timer for the designated inbound ports. The inbound  
ports close when the inactivity time expires. This closure is required because the wireless  
modem router cannot be sure when the application has terminated.

Dynamic DNS  
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 is, and the address can change  
frequently. In this case, you can use a commercial Dynamic DNS service. This type of service  
lets you register your domain to their IP address and forwards traffic directed at your domain  
to your frequently changing IP address.  
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic  
DNS service does not works because private addresses are not routed on the Internet.  
Your wireless modem router contains a client that can connect to the Dynamic DNS service  
provided by DynDNS.org. First visit their website at http://www.dyndns.org and obtain an

account and host name that you configure in the wireless modem router. Then, whenever  
your ISP-assigned IP address changes, your 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 wireless modem  
router at http://hostname.dyndns.org.  
On the Advanced tab, select Advanced Setup > Dynamic DNS.  
To set up Dynamic DNS:  
1. Register for an account with one of the Dynamic DNS service providers whose  
addresses appear in the Service Provider list.  
2. Select the Use a Dynamic DNS Service check box.

to your account, not your host name.  
6. Type the password (or key) for your Dynamic DNS account.  
7. Click Apply to save your configuration.  
Static Routes  
Static routes provide additional routing information to your wireless modem router. Under  
usual circumstances, the 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 have to configure static routes only for unusual cases such as multiple wireless  
modem routers or multiple IP subnets on your network.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
As an example of when a static route is needed, consider the following case:  
•
•
Your primary Internet access is through a cable modem to an ISP.  
You have an ISDN wireless modem router on your home network for connecting to the  
company where you are employed. This wireless modem router’s address on your LAN is  
192.168.1.100.  
•
Your company’s network address is 134.177.0.0.  
When you first configured your 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 192.168.1.x addresses. With this configuration, if you  
attempt to access a device on the 134.177.0.0 network, your 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 have to define a static route, telling your wireless modem router that  
134.177.0.0 should be accessed through the ISDN wireless modem router at 192.168.1.100.  
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 wireless modem router at 192.168.1.100.  
•
•
A metric value of 1 works since the ISDN wireless modem router is on the LAN.  
Private is selected only as a precautionary security measure in case RIP is activated.

3. In the Route Name field, type a name for this static route (for identification purposes only).  
4. 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.  
5. Select the Active check box to make this route effective.  
6. Type the IP address of the final destination.  
7. Type the IP subnet mask for this destination. If the destination is a single host, type  
255.255.255.255.  
8. Type the gateway IP address, which has to be a wireless modem router on the same LAN  
segment as the N750 Modem Router.  
9. Type a number from 1 through 15 as the metric value.  
This value represents the number of wireless modem routers between your network and  
the destination. Usually, a setting of 2 or 3 works, but if this link is a direct connection, set  
it to 1.

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 wireless  
modem router does not allow any device to automatically control the resources, such as  
port forwarding (mapping) of the wireless modem router.  
Advertisement Period. The advertisement period is how often the wireless modem  
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 can  
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 accessing the wireless modem 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.

Quick Tips  
This section describes tips for troubleshooting some common problems.  
Sequence to Restart Your Network  
Be sure to restart your network in this sequence:  
1. Turn off and unplug the modem.  
2. Turn off the wireless modem router and computers.  
3. Plug in the modem and turn it on. Wait 2 minutes.  
4. Turn on the wireless modem router and wait 2 minutes.  
5. Turn on the computers.  
Check Ethernet Cable Connections  
Make sure that the Ethernet cables are securely plugged in.  
•
The Internet status LED on the wireless modem router is lit if the Ethernet cable  
connecting the wireless modem router and the modem is plugged in securely and the  
modem and wireless modem router are turned on.  
•
For each powered-on computer connected to the wireless modem router by an Ethernet  
cable, the corresponding numbered router LAN port LED is lit.  
Wireless Settings  
Make sure that the wireless settings in the computer and wireless modem router match  
exactly.  
•
•
For a wirelessly connected computer, the wireless network name (SSID) and wireless  
security settings of the wireless modem router and wireless computer need to match  
exactly.  
If you set up an access list in the Advanced Wireless Settings screen, you have to add  
each wireless computer’s MAC address to the wireless modem router’s access list.  
Network Settings  
Make sure that the network settings of the computer are correct.  
•
Wired and wirelessly connected computers need to have network (IP) addresses on the  
same network as the wireless modem router. The simplest way to achieve this address  
commonality is to configure each computer to obtain an IP address automatically using  
DHCP.  
•
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.

Cannot Log In to the Router  
If you are unable to log in to the wireless modem router 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 wireless modem router as described in the previous  
section.  
Make sure that your computer’s IP address is on the same subnet as the wireless modem  
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.  
If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and  
Mac OS generate and assign an IP address if the computer cannot reach a DHCP server.  
These autogenerated 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 wireless modem router, and  
reboot your computer.  
•
•
If your wireless modem router’s IP address was changed and you do not know the current  
IP address, clear the wireless modem router’s configuration to factory defaults. This  
procedure sets the wireless modem router’s IP address to 192.168.0.1. This procedure is  
explained in Factory Settings on page 146.  
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using  
Internet Explorer, click Refresh to be sure that the Java applet is loaded.  
•
•
Try quitting the browser and launching it again.  
Make sure that you are using the correct login information. The factory default login name  
is admin, and the password is password. Make sure that Caps Lock is off when you  
enter this information.  
•
•
If you are attempting to set up your NETGEAR wireless modem router as an additional  
router behind an existing router in your network, consider replacing the existing router  
instead. NETGEAR does not support such a configuration.  
If you are attempting to set up your NETGEAR wireless modem router as a replacement  
for an ADSL gateway in your network, the wireless modem router cannot perform many  
gateway services, for example, converting ADSL or cable data into Ethernet networking  
information. NETGEAR does not support such a configuration.  
Cannot Access the Internet  
If you can access your router but you are unable to access the Internet, first determine  
whether the wireless modem router can obtain an IP address from your Internet service  
provider (ISP). Unless your ISP provides a fixed IP address, your wireless modem router  
requests an IP address from the ISP. You can determine whether the request was successful  
using the Router Status screen.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
To check the WAN IP address:  
1. Start your browser, and select an external site such as http://www.netgear.com.  
2. Access the wireless modem router interface at http://www.routerlogin.net.  
3. Select Administration > Router Status.  
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your wireless  
modem router has not obtained an IP address from your ISP.  
If your wireless modem router cannot obtain an IP address from the ISP, you might need to  
force your cable or DSL modem to recognize your new wireless modem router. Restart your  
network, as described in Sequence to Restart Your Network on page 135.  
If your wireless modem router is still unable to obtain an IP address from the ISP, the problem  
might be one of the following:  
•
Your Internet service provider (ISP) might require a login program.  
Ask your ISP whether it requires 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 Internet  
Basic Settings screen.  
•
Your ISP allows only one Ethernet MAC address to connect to the 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  
wireless modem router’s MAC address.  
-
Configure your wireless modem router to clone your computer’s MAC address.  
If your wireless modem 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 wireless modem  
router’s configuration, reboot your computer, and verify the DNS address. You can  
configure your computer manually with DNS addresses, as explained in your operating  
system documentation.  
•
•
Your computer might not have the wireless modem router configured as its TCP/IP  
gateway.  
If your computer obtains its information from the wireless modem router by DHCP, reboot  
the computer, and verify the gateway address.  
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 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.

N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000  
Troubleshoot PPPoE  
If you are using PPPoE, try troubleshooting your Internet connection.  
To troubleshoot a PPPoE connection:  
1. Log in to the wireless modem router.  
2. Select Administration > Router Status.  
3. Click Connection Status. If all of the steps indicate OK, then your PPPoE connection is  
working.  
If any of the steps indicate Failed, you can attempt to reconnect by clicking Connect. The  
wireless modem router continues to attempt to connect indefinitely.  
If you cannot connect after several minutes, you might be using an incorrect service name,  
user name, or password. There might also be a provisioning problem with your ISP.  
Note: Unless you connect manually, the wireless modem router does not  
authenticate using PPPoE until data is transmitted to the network.  
Troubleshoot Internet Browsing  
If your wireless modem router can obtain an IP address but your computer is unable to load  
any web pages from the Internet, check the following:  
•
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 wireless modem router’s configuration, restart your  
computer.  
Alternatively, you can configure your computer manually with a DNS address, as  
explained in the documentation for your computer.  
•
•
Your computer might not have the wireless modem router configured as its default  
gateway.  
Reboot the computer, and verify that the wireless modem router address  
(www.routerlogin.net) is listed by your computer as the default gateway address.  
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 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.
