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.
Network Connection
Problems
If the Link LED on the SpeedTouch™121g does not light, or if you cannot access any
network resources from the computer, check the following:
 Make sure the driver and utility software is installed correctly. If necessary, try
uninstalling and then reinstalling the software.
 Make sure the computer and other network devices are powered on.
 The access point that you are connecting to might be defective. Try connecting
to another access point.
 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.
