Error Message    %DOT1X-3-INVALID_WPA_KEY_MSG_STATE: Received invalid [chars] msg in 
[chars] state - [chars]; len [int], key type [int], client 
[hex]:[hex]:[hex]:[hex]:[hex]:[hex]

Explanation    Client authentication failed because of an authentication protocol error between the client and access point.

Recommended Action    If the problem persists, try upgrading the client driver software or using different client software to isolate the cause. Also investigate possible intruder activity.
