ath9k and WPA2-Ent. [UPDATE]

in our company we are moving from WPA2-Personal to WPA2-Ent and I have a problem with my card AR9485 (ath9k module).

my wpa_supplicant.conf:


Here is a debug from: wpa_supplicant -i wlan0 -c wpa_supplicant.conf -dd


reading from file wpa.debug.tcpdump, link-type EN10MB (Ethernet)
17:31:42.637147 EAP packet (0) v2, len 62, Request (1), id 1, len 62
                 Type Identity (1), Identity:

after its start over and over again.

I check this configuration on another laptop (Broadcom BCM43xx  on brcmsmac module) and everything works great.
Here is a debug output from  Broadcom BCM43xx chipset.

The difference is after SSL session.  On 299 line ath9k get "EAPOL: SUPP_BE entering state TIMEOUT" where on BMC chipset on 303 line get "RX EAPOL (...)". I check on radius server, and the packets are sending back.

I checked on LEAP security (without SSL), and everything pass well.
Any thoughts? I don't know how debug better this issue.


On linux-lts  (3.0.70-1-lts) everything is OK
