We have a 2006 Series Wireles LAN Controller (AIR-WLC2006-K9) set up with 5 deployed Aironet 1130AG Series (AIR-LAP1131AG-A-K9) access points. We have one wireless network configured using WPA + WPA2, AES encryption, 802.1X key management, RADIUS with local EAP Authentication.

We have been banging our heads against this for some time now and have never been able to find a configuration solution that garauntees a decent quality of service to our wireless clients.
