Wireless LAN Configuration Wizard  
The Ericsson W3x may function as a WLAN Access Point (AP) for the local  
network providing wireless client(s) with Internet and LAN access. The  
Wireless LAN Configuration Wizard guides you step-by-step through the  
basic setup for the Wireless LAN (WLAN).  
Note: The wireless setup typically requires configuration of both the  
Ericsson W3x and the wireless clients. For more information about  
configuring wireless clients, see 6.2 – Wireless LAN Settings.

Network Name  
All clients on the local wireless network share a common Service Set  
IDentifier (SSID) or network name. This name is required to establish  
connection between the Ericsson W3x and the wireless client(s), and to  
distinguish the wireless network from any other(s) that may be in use  
nearby. Only devices configured with the same network name as the one  
set on the Ericsson W3x can obtain access to it.  
Figure 15 – Wireless LAN: Network Name (SSID) page  
The network name is case-sensitive (distinguish between uppercase and  
lowercase letters) and can be changed to any combination of numbers (0 –  
9), letters (a – z), and hyphens (-) with a maximum length of 32 characters.  
If the “Enable SSID broadcast” option is selected, your local wireless  
client(s) will find the network name when scanning the air. If not, the  
network name is hidden and has to be manually provided to the wireless  
client(s).  
If you want to change the preconfigured network name (MBR), type a new  
name in the “Network name (SSID):” field and also select if the SSID shall  
be hidden or not.  
Click Next to proceed.  
3.3.3  
Wireless LAN Authentication  
All communication on the wireless LAN can be protected from potential  
intruders and eavesdroppers through standard authentication and  
encryption methods.

Authentication is used to restrict access to the wireless network and  
encryption is the translation of data into a form that cannot be easily  
understood by unauthorized users. The encrypted data can only be sent  
and received by users with access to a private encryption key.  
Note: Make sure that the operating system(s) and Wireless LAN  
interface(s) of the wireless client(s) support the selected  
authentication method.  
Figure 16 – Wireless LAN: Authentication page  
Select one of the authentication methods from the “Authentication” drop-  
down list. The available options are as follows:  
Open (No security);  
f you select “Open” as authentication method no client configuration is  
needed but be aware of that the WLAN will now be open without any  
kind of security.  
WEP-64, WEP-128 (Low security);  
WEP (Wired Equivalent Privacy) is considered to be a low security  
option. WEP encrypted data is translated into blocks of either 64 bits  
length or 128 bits length.  
WPA, WPA2 (High security);  
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most  
reliable security options. WPA encryption uses the Temporal Key  
Integrity Protocol (TKIP) while WPA2 encryption follows the Advanced  
Encryption Standard (AES). AES offers a higher level of security and is  
approved for sensitive corporate and government data transmission.

Make sure that the DHCP server IP address range is included in the  
new subnet. If you want to change the subnet not to include the DHCP  
IP address range, you first have to disable the DHCP server.  
If port forwarding rules have been configured, those settings have to be  
removed before changing the IP address or subnet mask. For  
information, see section 3.7.3 – Port Forwarding.  
To change the LAN IP address or subnet mask of the Ericsson W3x, type

DHCP Server  
The Ericsson W3x incorporates a DHCP (Dynamic Host Configuration  
Protocol) server which dynamically assigns IP addresses to devices on the  
LAN/WLAN whenever they are switched on. The DHCP server also puts  
the hostname, supplied by the client DHCP request, in the local DNS  
(Domain Name System/Service) proxy.  
The DNS proxy contains a small database of local host names and  
addresses supplied by client DHCP requests. In addition it also caches  
requests to remote DNS servers.

Lease Time [sec]:  
The DHCP server uses the concept of a  
“lease”, that is the amount of time that a given  
IP address will be valid for a specific device. If  
the lease time expires and the device is still  
connected, the lease is automatically renewed.  
The preconfigured lease time is 7200 seconds  
(2 hours) and a valid value must be within the  
range 60 and 2147483647 seconds.  
Note: If you want to configure a connected device with a static IP  
address, make sure that the address is outside the DHCP server IP  
address range.  
Before changing any of the DHCP server settings, read the following:  
The DHCP server IP address range has to be on the same subnet as  
the LAN IP address on the Ericsson W3x.  
The DHCP server IP address range must not include the LAN IP  
address on the Ericsson W3x.  
If port forwarding rules have been created, those settings have to be  
removed before changing the DHCP server IP address range. For  
more information, see section 3.7.3 – Port Forwarding.  
To change the DHCP server settings, type the new values in the  
corresponding fields and click Apply to save the settings.

3.6.7  
Network Name (SSID)  
All clients on the WLAN share a common network name or SSID (Service  
Set IDentifier). This name is required to establish connection between the  
Ericsson W3x and other wireless client(s) and to distinguish the WLAN from  
any other(s) that may be in use nearby.  
Only clients configured with the same network name (SSID) as the one set  
on the Ericsson W3x can obtain access to it.  
Note: It is recommended to change the preconfigured network name  
“MBR” to something else that makes it harder for unauthorized  
persons to access your wireless network.  
The following settings concerning the network name are displayed and can  
be modified on the Wireless LAN page:  
Table 16 - Network name description  
Text  
Description  
Network name (SSID):  
The network name (SSID) of the wireless  
network.  
The network name is case-sensitive  
(distinguish between uppercase and  
lowercase letters) and can be changed to  
any combination of numbers (0-9), letters  
(a-z), and hyphens (-) with a maximum  
length of 32 characters.  
Enable SSID broadcast  
If “Enable SSID broadcast” is checked, the  
SSID is continuously broadcasted and any  
nearby wireless client(s) will find it when  
scanning the air.  
If the checkbox is cleared, the SSID will be  
hidden and in this case the name has to be  
provided manually to every wireless client  
where access is to be granted.  
To change settings for the Network Name (SSID), type the new values in  
the corresponding fields and click Apply to save the settings.  
3.6.8  
WLAN Security  
All communication on the wireless network can be protected using different  
authentication and encryption methods. The most common is to encrypt the  
WLAN using an encryption method such as WEP, WPA and WPA2.  
1/1551-CRH 102 168 Uen Rev A 2008-12-16  
43  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Configuration and Management  
Which authentication and encryption method that should be used depends  
on what is supported by the connected wireless client(s).  
Note: Each wireless client must be configured to use exactly the same  
security mode and key/passphrase as the Ericsson W3x or they will  
not be able to connect.  
In the “Authentication” drop-down list you select which type of  
authentication/encryption you want to use for your WLAN. The following  
subsections describe the authentication methods supported by the Ericsson  
W3x.  
3.6.8.1  
3.6.8.2  
Open (No security)  
If you select “Open” as authentication method no client configuration is  
needed but be aware of that the WLAN will now be open without any kind  
of security. For example, it is now possible for anyone with a computer and  
a wireless interface card to connect to the Ericsson W3x at any time and  
having access to both your home network and Internet connection.  
WEP and WEP Encryption Key (Low security)  
WEP (Wired Equivalent Privacy) is considered to be a low security option.  
The data is encrypted into blocks of either 64 bits length or 128 bits length.  
WEP encrypted data can only be sent and received by users with access to  
a private encryption key. This means that each client on your wireless  
network has to be manually configured with exactly the same key as the  
one entered in the Ericsson W3x in order to allow encrypted data  
transmissions.  
WEP-64 bit data encryption requires a key including 10 characters.  
Only hexadecimal numbers 0-9 and letters a-f (uppercase or  
lowercase) are allowed.  
WEP-128 bit data encryption requires a key including 26 characters.  
Only hexadecimal numbers 0-9 and letters a-f (uppercase or  
lowercase) are allowed.  
Enter an encryption key in the “Passphrase / Key” field and click Apply to  
save the settings.  
3.6.8.3  
WPA/WPA2 and Passphrase (High security)  
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most  
reliable security options. WPA encryption uses the TKIP (Temporal Key

Configuration and Management  
Integrity Protocol) while WPA2 encryption follows AES (Advanced  
Encryption Standard). AES offers a higher level of security and is approved  
for sensitive corporate and government data transmission. WPA/WPA2  
Mixed enables connection of both WPA and WPA2 clients.  
WPA and WPA2 authentication and encryption require a passphrase. A  
passphrase is a sequence of words or other text and is similar to a  
password in usage, but is generally longer for added security.  
Each client on your wireless network has to be configured with exactly the  
same passphrase as the one entered in the Ericsson W3x in order to allow  
encrypted data transmission.  
A WPA or WPA2 passphrase is case sensitive (distinguish between  
uppercase and lowercase letters) and consists of between 8 and 63  
characters. It is recommended that the passphrase contains at least 20  
characters.  
Enter a passphrase in the “Passphrase / Key” field and click Apply to save  
the settings.  
Note: Avoid using special characters (such as :, “ and ¤) when entering a  
passphrase.  
3.6.9  
Connected Devices  
The “CONNECTED DEVICES” list on the Wireless LAN page includes the  
MAC (Media Access Control) addresses of all wireless clients currently  
connected to the Ericsson W3x.  
3.6.10  
Whitelist  
A common method of restricting WLAN access is to specify the MAC  
address(es) in a “whitelist” for those computers to be granted access to the  
WLAN. This kind of whitelist is also known as “MAC Association” or “MAC  
Access list”.  
Up to 20 MAC addresses for wireless clients can be added to the whitelist.  
Once the whitelist has been enabled, only clients with an associated MAC  
address are allowed to connect to the WLAN.  
Note: This feature does not require any configuration of clients, but it is  
recommended that some kind of encryption (WEP, WPA/WPA2) is  
used in combination with the whitelist.

3.6.10.1  
Add Client(s) to the Whitelist  
To add a client to the whitelist, you can either copy/paste a MAC address  
from the “CONNECTED DEVICES” list or type the client’s MAC address in  
the field below “WHITELIST” and click Add .  
The MAC address has the form of xx:xx:xx:xx:xx:xx, where x is a  
hexadecimal number (0-9 and/or letters a-f), for example  
00:80:37:8c:10:46.  
Check “Enable whitelist” to activate the feature and click Apply to save the  
settings.  
To delete a MAC address from the whitelist, click the Delete button next to  
the MAC address to delete.  
3.6.10.2  
Find a Wireless Client MAC Address  
The MAC address for a WLAN adapter is normally found on the product  
label. For internal wireless PCI cards running on Windows platform, the  
command ipconfig /all(run from a Command Prompt window) can be  
used to display the MAC address (displayed as “Physical Address” against  
the network adapter). For example:

NAT  
The Ericsson W3x includes a NAT (Network Address Translation) service.  
With this service several computers on a LAN/WLAN can share the same  
Internet connection using a single public IP address.  
Devices on the LAN/WLAN use dedicated private IP addresses, which  
cannot be used on the Internet. When a computer on the LAN/WLAN want  
to send a data package to the Internet, its IP address is automatically  
translated by NAT to an external (public) IP address allowed on the  
Internet. When a reply receives to this external IP address, it is translated  
back to the origin private IP address to be able to found its way back to the  
sending computer on the LAN/WLAN.  
In this way, details about the local devices remain private and it is not  
possible to access a local computer on the LAN/WLAN directly from the  
Internet.  
The NAT page includes the following settings:

3.7.1  
UPnP IGD  
The Ericsson W3x supports the Universal Plug and Play (UPnP) Internet  
Gateway Device (IGD) standard. UPnP IGD is used to provide automatic  
port forwarding allowing communication between certain Internet  
applications and the local network. When UPnP IGD is enabled, programs  
like MSN Messenger® and most network enabled games are allowed to  
pass the NAT service.  
UPnP IGD is enabled by default, but if you want to disable the feature, clear  
the “Enable UPnP IGD” check box and click Apply to save the settings.  
3.7.2  
Application Level Gateways  
From a security perspective, certain Internet applications, for example FTP  
applications that open additional ports upon transfer, are especially  
problematic to handle. An Application Level Gateway (ALG) provides a  
translation and transportation service for such a specific application.  
Incoming data packets are checked against existing NAT and packet  
filtering rules, IP addresses are evaluated and a detailed packet analysis is  
performed. If necessary, the contents of a packet are modified and if a  
secondary port is required, the ALG will open one. The Ericsson W3x  
includes ALG support for the following applications:

Port Forwarding  
Port forwarding is used to allow an external user to access a service  
residing on a server connected to the LAN (to cross the NAT border). It  
enables access to servers on the LAN from the Internet (e.g. Web server)  
and also enables applications to work from the LAN (e.g. games, voice and  
chat) to the Internet.  
Note: Port forwarding requires that the Ericsson W3x has a public IP  
address for Port Forwarding requests from the Internet to be  
handled correctly.  
This IP address is displayed on the Overview page as the  
“Internet: IP address”. A private IP address usually begins with 10,  
172, or 192. In this case, no incoming access from the Internet is  
allowed. For more information on public and private IP addresses,  
contact your service provider.  
When a computer on the Internet sends data to the public IP address of the  
Ericsson W3x, it needs to know what to do with the data. A port forwarding  
rule tells the Ericsson W3x which computer on the local area network to  
send the data to.  
The “PORT FORWARDING” section on the NAT page includes the  
following information about port forwarding rules:  
Table 18 - Port Forwarding description

Description  
NAT Port  
The NAT port number that the data traffic is allowed

In the following example, port forwarding is used to allow incoming access  
(from the external network (Internet)) to an internal web server (on the  
LAN/WLAN). The TCP protocol is used for data traffic. The NAT port 80 on  
the Ericsson W3x is open and the destination computer on the LAN with  
static server IP address 192.168.1.101 has appointed the server port 8080  
to be used.

File and Printer Sharing  
The Ericsson W3x supports local network storage and printer sharing  
through the USB port. If an external USB hub is connected, the Ericsson  
W3x supports connection of up to two storage devices and one printer at  
the same time.

implement file and printer sharing through SMB/CIFS. SMB and CIFS are  
the protocols used by Microsoft for sharing and the service is called “smb”  
on the Ericsson W3x.  
Linux Kernel auto detection of USB devices is used as part of the  
automatic configuration of the storage and printer sharing. When a new  
USB device (storage or printer) is detected, the Ericsson W3x  
automatically creates configuration files for Samba containing the new  
device. It then makes the smb service use the new configuration,  
thereby sharing the USB device via the SMB/CIFS protocol. This

process is totally automatic and there are no configuration parameters  
that can be set, other than renaming the shared resources.  
The Ericsson W3x uses a relatively low powered processor and is not  
designed to be a multi tasking platform. This means that you may  
experience problems during high load situations such as simultaneously  
downloading a large file through the mobile network and printing a large  
document or copying a large file to/from a shared storage device mounted  
on the Ericsson W3x. Don’t expect to have full performance on all  
simultaneous tasks.

Safe Removal of a USB Device  
Before removing a USB device from the Ericsson W3x wait until the activity  
LED (if any) on the device stops blinking or wait some 30 seconds to be  
sure there is not any ongoing/remaining write operations to be made.  
Host Name and Workgroup  
All devices on the LAN/WLAN that want to access a USB shared storage  
device or printer must belong to the same workgroup as the Ericsson W3x.

SIM Authentication  
It is possible to enter the PIN code for SIM authentication via a telephone  
connected to the Ericsson W35 (instead of the WUI). See section 3.1.1 –  
Enter PIN Code.  
Note: Emergency calls (i.e. 112 or 911) can always be made, even  
without a SIM card or the correct PIN code.  
Follow the steps below to enter the PIN code using a telephone connected  
to the Ericsson W35. The “PIN required” and “PUK required” tones are  
described in Table 24 – Information Tones on the next page.  
1. Pick up the telephone handset. If you hear the dial tone, you do not  
need to enter any PIN. If you hear the specific “PIN required” tone,  
proceed to step 2.  
2. Dial * <PIN>  
#
If the PIN is correct, you will hear the normal dial tone, which indicates  
that the voice service is activated and that it is possible to make phone  
calls.  
If the PIN is incorrect, you will hear the “PIN required” tone again.  
Repeat step 2.  
Note: If three attempts have been made with an incorrect PIN, the SIM  
card is blocked and you will hear a new tone, indicating that the  
PUK is required to unblock the SIM card.

Telephony and Fax (W35 only)  
To unblock the SIM card, dial the following sequence:  
* <PUK> * <new PIN> * <new PIN>  
#
If the PUK is correct and the new PIN codes agree, you will hear the normal  
dial tone, which indicates that the voice service is activated and that it is  
possible to make phone calls. Remember the new PIN for future use.  
If the PUK is incorrect or the new PIN codes do not agree, you will hear the  
“PUK required” tone again. Repeat the “unblock SIM card” sequence  
above.  
Note: If ten attempts have been made with an incorrect PUK, the SIM  
card is permanently blocked and a new SIM card is required.  
Contact your service provider.
