Troubleshooting Windows Does Not Detect the RoamAbout PC Card If the RoamAbout 802.11 a/b/g/ Client PC Card was properly working at one time in the client, the problem could be one of the following: • The PC card is no longer properly inserted. Reinsert the PC card into the card slot. • The PC card was removed and reinserted but the computer requires a reboot to recognize the PC card. Restart the computer. • The RoamAbout 802.11 a/b/g/ Client PC Card driver was improperly removed or corrupted. Remove the existing driver, then reinstall the driver. Client Cannot Connect to the AP If the client cannot connect to the AP but other clients can, check the following: • Open the Configuration Utility, if present, on the client. The utility status may provide the answer to the problem. • Verify that the Wireless Network Name (SSID) is correct. If the AP has Secure Access enabled, the client must specify the wireless network name, which is case‐sensitive. • The client is not in range of the AP. Move the client closer. • If using encryption with manual group keys, make sure that the client has the correct keys in the correct position (1, 2, 3, or 4). You may need to reenter the keys to make sure that the keys were typed in correctly. • If using 802.1X authentication, make sure the client is configured correctly.
