Symptom Solution
Basic troubleshooting,
applicable for all problem
situations
Inspect all cables and connections.
Check whether your card is fully inserted into the slot
Check the Web site for your computer to verify whether you have
the latest BIOS for your system. If not, download the newest BIOS
version, and follow the upgrade instructions.

installed and running properly: go to Control
Panel/System/Hardware/Device Manager/PCMCIA Card and verify
that the controller is present and shows no errors.
Check the Control Panel/PC Card application to confirm that your
card is recognized by the system.
In the Control Panel/Network application, make sure that you
have appropriate Clients and Protocols installed.
Check the Control Panel/Network application. Select 10/100 LAN
