I am trying some ath9k virtual clients against an ASUS N66U.
Kernel is 3.3.3+, but we've been seeing weird things since at
least 3.0 kernel with another Asus AP, but haven't looked at
the problem in detail on older kernels yet.
The issue seems to be that the ath9k side thinks all is well,
but the N66U shows it as not authenticated.
If anyone has any ideas on how to go about debugging
this, please let me know.
sta11 is :0C, and is not working properly
sta12 is :0D, and is working fine.
Here is part of the N66U wifi log showing that it
thinks sta11 is not authorized:
00:95:95:00:00:0C associated
00:95:95:00:00:0D associated authorized
Here's the supplicant logs:

Only thing I notice above is that the key negotiation completed after the connection completed,
and appears duplicated???
