9 Troubleshooting
This chapter provides solutions to common problems that usually occur during the installation and
operation of the 802.11a Wireless LAN Network Adapter. Read the following descriptions below if
you are having problems. If you cannot find an answer here, please contact an field application
engineer for assistance.
1. My computer does not recognize the 802.11a CardBus reference 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
802.11a NDIS driver installed. Remove the old driver and try again.
2. The 802.11a Wireless LAN 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 802.11a Wireless LAN 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.
3. Stations cannot associate in ad hoc mode.
Make sure the Same Service set identifier is specified for all stations that need to join the
same ad hoc network. Set up one station to establish a BSS and wait briefly before setting
up other stations. This prevents several stations from trying to establish a BSS at the same
time, which can result in multiple singular BSSs being established, rather than a single BSS
with multiple stations associated to it.
4. The station cannot access the Internet in the infrastructure configuration.
Make sure the station is associated and joined with the AP. If Wired Equivalent Privacy
(WEP) security is enabled on the AP, the station must have the proper WEP keys specified.
Also make sure TCP/IP properties are correctly configured.
5. ARCCSEL Country Code Selector shows the following error message: No
configurable 802.11a network cards were found in this system.
Make sure the 802.11a Wireless LAN Network Adapter has Release 1.1 EEPROM contents
programmed. 802.11a CardBus Reference Design boards that were released prior to
Release 1.1 do not contain the regulatory domain information in the EEPROM. Therefore,
the country code selection utility will not recognize the card.
