Subject: Issue with authentication to Aerohive APs




Hello,


I'm writing on behalf of about 4 or 5 users that are having issues
connecting to a WLAN that I manage. The majority of the information can be
found at the following link, including relevant logs. I've enclosed the
packet capture
 from next to the station with failed authentications.

http://community.aerohive.com/aerohive/topics/issue_with_linux_connectivity
_in_a_high_density_wlan

We seem to have narrowed it down to a possible driver or firmware bug, but
I'm reliant on the user to provide me requested information. At the moment
I'm requesting that the user upgrade or downgrade his firmware or kernel in
 case that changes the behavior.

I'd like to submit this to this group for review, and to see if you can
elucidate what might be happening so I that I can work towards a solution
with these users.

Thanks!

For completeness, what device/driver pair(s) and kernel versions are the Linux 
user(s) running?

How did you capture/filter the attached file? It shows no
acknowledgement of the EAPOL packets, but no retries either, so you
probably filtered out the acknowledgements. That leads me to believe
that maybe there was something wrong with those EAPOL frames, maybe
wpa_supplicant didn't get or didn't expect them?

What makes you so sure it's a driver/firmware bug rather than a bug
related to wpa_supplicant or interaction with it?
