USB Adapter Installation Problems

If your computer cannot find the Cheetah Wireless-3501C USB Adapter or the network
driver does not install correctly, check the following items:
•Make sure the adapter is connected to the USB port.
•Try the adapter in another USB port. If this also fails, try using another WN3501C
wireless adapter that is known to operate correctly.
•Make sure your computer is using the latest BIOS.
•If there are other network adapters in the computer, they may cause conflicts. Disable
or remove the other adapters from the computer and test the wireless adapter
separately.
•Check for a defective computer or USB port by trying the adapter in another computer
that is known to operate correctly.
•If there are still difficulties, remove the wireless adapter. Delete the file “Vnetusbr.sys”
from:

c:\windows\system (in Windows 98/Me)

c:\winnt\system32\drivers (in Windows 2000)

c:\windows\system32\drivers (in Windows XP)

Click “Start/Settings/Control Panel.” Delete the adapter from the network

configuration menu. Restart the PC and reinstall the adapter.

Network Connection Problems

If the LED on the USB adapter is not lit, or if you cannot access network resources from
the computer, check the following:
•Make sure the correct software driver is installed. Try reinstalling the driver.
•Make sure the computer and other network devices are receiving power.
•The access point you want to connect to may not be functioning correctly. Try using
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.
