I have a lot of client in one configuration who have problem with the message:
EAPOL-key M2 with invalid MIC
4402-12 in 220.127.116.11 (and ER) sw release
AP1242 with 2 4941 in diversity mode
SSID in WPA-TKIP PSK and DHCP on the WLC.
A lot of client can't connect to the switch. With Intel card, i have try the lasted drivers, and it's ok, but with some device like Intermec on windows mobile, it's not working. You can look the trace in the file log.
I just had a few problems with the same error. It turned out that this was an issue with the client device NEEDING the key to be entered in HEX (even though it would take an ASCII if you typed it). I converted the ASCII PSK I'd configured on the controller into HEX and entered it on the client, and it works fine. You might want to try that if you haven't already.
