Due to a bug in some versions of Cisco wireless LAN controller software a 802.11w-capable client, so any Windows 8 logo certified wireless NIC driver, cannot connect to an SSID on Cisco (controller-based) CUWN using WPA or WPA2 key management with
AES encryption. I have written up some more on this here ; details from Cisco are on a mailing list archive here and
from Microsoft here.
