I currently have a Cisco AIR-AP1231G-A-K9 that is running IOS version 12.3(8)JEA1. I am trying to setup WPA2 "Personal" (WPA2-PSK) with a client running Windows XP SP2. The WLAN Nic is a Cisco a/b/g PCMCIA, driver version 22.214.171.124. I have configured the PSK on both the AP and the client and verified that I did not make a typing mistake. I have installed the Microsoft WPA2 hotfix to see if that was causing the problem but it is not. The actual problem is that the client says it's "Authenticated" but will not allow any traffic to pass through. Whenever I created an SSID NOT using WPA2-PSK, the client can ge an IP address and things function normally. Here is the current AP configuration:
I have tried upgrading the WLAN NIC drivers to the latest version (3.5 I believe) but it does not help. If I run the troubleshooting task of the Aironet Desktop Utility is sasys that the Authentication tests failed, even though the status shows me as "Authenticated". Perhaps there is something in the above config that I am missing.
