USB Adapter Installation Problems
If your computer cannot find the Wireless USB Adapter or the network driver does
not install correctly, check the following items:
• Make sure the adapter is connected to the USB port. Check for any hardware
problems, such as physical damage to the adapter's connector.
• 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.
If your wireless station cannot communicate with a computer on the Ethernet LAN
when configured for Infrastructure mode, check the following:
