WPA using cisco 1200 series access point with netgear adapter

[gayathribe]

I am using cisco Aironet 1200 series access point.I tested WPA encryption and it is giving authentication failure. Previously i used the same encryption algorithm and tested with linksys access point.It was working fine. In both the cases i used netgear adapter WG111v2. Can anyone suggest what may be the problem?

I tried to access without encryption.It is working.Also i tried in adhoc mode with encryption and able to access from PC.

But with encryption, i am not able to access wireless network from my pxa processor. It was quiet working fine when i used linksys access point.
