Troubleshooting
This chapter provides solutions to common problems that usually occur
during the installation and operation of the Atheros Wireless Network
Adapter. Read the following descriptions for solutions to common problems.
If you cannot find an answer here, please contact an Atheros field application
engineer for assistance.
1. My computer does not recognize the Atheros CardBus card.
Make sure the CardBus card is properly inserted into a 32-bit CardBus
slot. If Windows does not detect the hardware upon insertion of the card,
the system could have a previous Atheros NDIS driver installed. Remove
the old driver and try again.
2. The Atheros Wireless Network Adapter does not work properly after
the driver is installed.
Re-insert the CardBus card into the slot. A beep should be heard if the
adapter is properly inserted. Go to Device Manager and make sure the
Atheros Wireless Network Adapter exists under the network adapters
device node. If you see the yellow exclamation mark then there are
conflicting resources. In this case, make sure the computer system has a
free IRQ and make sure you have installed the proper driver. Uninstall
the driver, restart the system, and repeat the driver installation steps if
necessary.
