Troubleshooting
Windows Troubleshooting Tips
Many problems can easily be diagnosed using the tools provided by Microsoft Windows, such
as the PING utility, Network Monitors, TELNET and FTP. Other more elaborate tools, such as
LAN analysers, for example NETXRAY or Novell's LAN analyser, may also be used.
Some common problems exhibited when the Wireless LAN USB Card has not been properly
installed include:
■
Windows 95/98 does not recognize the Wireless LAN USB Card when installed.
■
Verify that Windows 95/98 Wireless LAN USB support is installed.
■
Verify the computer has a Plug and Play BIOS.
■
The driver fails to load.
■
A resource conflict could exist. Use the Device Manager to resolve resource conflicts.
Select the System applet from the Control Panel.
■
The workstation cannot associate to the Wireless access point.
■
Verify the adaptor ESSID matches the ESSID of the Access Point.
■
Degraded performance from the Wireless LAN USB Card.
■
Verify a secure antenna connection on the adaptor.
■
Network drive mappings disappear when the laptop suspends or the adaptor is removed
then reinserted.
■
Windows does not automatically restore network drive mappings under these
conditions. Log out and log in again, or restart the machine to restore the connections.
■
Non-functioning Wireless LAN USB Card LED's
■
Verify the Card Type parameter is set correctly.
■
Verify that the adaptor ESSID matches the ESSID of the AP.
■
An adaptor associates with an access point, but the WLAN USB Adaptor Utility fails to
discover the access point or work properly.
■
The WLAN USB Adaptor Utility is closely integrated with the driver. Investigate for
system resource conflicts and reload or reconfigure driver software as needed.
