Connection/disconnection problems with wpa_supplicant and hostapd when using WPA2 encryption

[Adrien Decostre]

Dear Jouni,

Thanks a lot for this quick answer.
The ath9k driver is used on the access point with hostapd.
In attachment, there is a full log file from wpa_supplicant where the
client disconnects before the completion of the authentication
procedure (due to limited size of the attachment, I have cut the part
of the log showing successful authentication).
Up to now, I have seen this problem with different PCs among other one
with a rt2800usb driver

Is there a way to reduce the authentication timeout (now currently set
to 10sec.) such that in case of "authentication failure", the
authentication procedure is restarted sooner?


Thanks in advance for your answer.
