hi PCFREAK49 (Why do I think I know u??? anyways...)
If you are using automous access points, it is not possible to use mac authentntication with WPA... However ther eis a association filter option that you can use with WPA.. (check the configuration guide )
Check this FAQ:
A. The only level of security for MAC authentication is to check the MAC address of the client against a list of permitted MAC addresses. This is considered very weak. In earlier Cisco IOS Software releases, you could configure MAC authentication and WPA to encrypt the information. But because WPA itself has a MAC address that checks, Cisco decided not to allow this type of configuration in later Cisco IOS Software releases and decided only to improve security features.
If you use ausing WLC
Then you can configurationn WPA +MAC filter... that should do it..
( again... if needed check the wireless lancontroller configurationn guide that matches your WLC software version)
