This should be set to the same value as the SSID of the access point or
wireless router to which you are connected. Set this value to ANY to allow
connection to any access point. This assumes that the access points are
broadcasting the SSID. If not, then set the SSID to the value configured on the
Access Point.

How to set up WEP
WEP provides a basic level of security, preventing unauthorized access to the
network and encrypting data transmitted between wireless clients (and the access

strings) that are manually distributed among all clients that want to use the
network.
To use the WEP function, take the following steps:

How to set up WPA
Wi-Fi Protected Access is an interoperable security enhancement that strongly
increases the level of data protection and access control for existing and future
wireless LAN systems. It is derived from and will be forward-compatible with the
upcoming IEEE 802.11i standard. WPA employs a combination of several
technologies to provide an enhanced security solution for 802.11 wireless networks,
including TKIP (Temporal Key Integrity Protocol) for data protection and 802.1x for
authenticated key management. WPA provides a simple operating mode that uses
just a pre-shared password for network access. The Pre-Shared Key mode uses a
common password for user authentication that is manually entered on the access
point and all wireless clients on the network. Manual Pre-Shared Key supports up to
64 characters.
To use the WPA function, take the following steps:
1
2
3
Select WPA-PSK from the Authentication Type drop-down menu.
Type in the Shared Secret Key (PSK).
Click Apply changes to allow the settings to take effect.
If there is no authentication server on your network, you can issue the Pre-Shared
Key to your SpeedTouch™121g. Be sure to use the same key for the wireless access
point and your SpeedTouch™121g.
Advanced The Advanced sub-tab allows you to configure advanced power and wireless
performance parameters of the SpeedTouch™121g
This feature is intended for advanced users only!

Adapter Installation
Problems
If your computer cannot find the SpeedTouch™121g or the driver software does not
install correctly, check the following:
ꢀ
Make sure the SpeedTouch™121g is securely connected with the USB port.
Check for any hardware problems, such as physical damage to the card’s
connector.
ꢀ
Try the SpeedTouch™121g in another USB port. If this also fails, test your
computer with another wireless USB adapter that is known to operate
correctly.
ꢀ
ꢀ
Make sure your computer is using the latest BIOS, check the manual of your
computer for details.
If there are other network adapters in the computer, they may be in conflict.
Remove the other network adapters from the computer and test the wireless
adapter separately.
ꢀ
Check for a defective computer or USB connection by trying the adapter in
another computer that is known to operate correctly.
If all fails, and the card still does not work, take out the SpeedTouch™121g.
Uninstall the driver and utility from your system, then go to “Control Panel” and
delete the SpeedTouch™121g from your network configuration menu. Restart your
computer and reinstall the SpeedTouch™121g, the driver and the utility software.

If you cannot access a Windows or NetWare service on the network, check that
you have enabled and configured the service correctly. If you cannot connect
to a particular server, be sure that you have access rights and a valid ID and
password.
ꢀ
If you cannot access the Internet, be sure you have configured your system for
TCP/IP.
If your SpeedTouch™121g cannot communicate with a device in the Ethernet LAN
when configured for Infrastructure mode, check the following:
ꢀ

ꢀ
ꢀ
Make sure the access point that the SpeedTouch™121g is associated with is
powered on.
Check the SSID of the access point that you are connecting to, and make sure
you set the SpeedTouch™121g to the same SSID.
If there is still no connection, change the radio channel of the access point and
all the clients associated to this access point.
Check if the WEP or WPA settings have been enabled in the access point to
which you are connecting to. Make sure that the encryption, default key and
passphrase settings of the adapter are set to the same as the access point.
Contact your network administrator for more information.
