[ath9k-devel] ath9k_htc: deauthenticated Reason: 16

[jacopo mondi]

Hi all,
	using ath9k_htc with an AR9271 device for connecting to a
standard WPA-PSK protected 802.11/g network my connection is not stable
and i receive back 
wlan0: deauthenticated from XXXXXXXXXXXXX (Reason: 16)
every 30seconds..

I'm using a custom 2.6.36-omap-pm kernel over a omap3 beagleboard.
Could anyone explain what does 'Reason 16' means?

Thanks a lot..

	j

group key handshake timed out. Please apply the following patch
and check it.

Also please use the latest firmware which we have recently posted in
this newsgroup. The title of the discussion is "TKIP MIC failure with
netgear AP"

Thank you all for your responses...

I'm using latest firmware from linux-firmware git repo (size corresponds
to the one mentioned in the post you were referring to).
I've also applied that 1 line patch suggested by Rajkumar Manoharan.

I've done different tries, and registered logs, in order to provide
more debug informations I can.

ath9k_htc (no debug, nohwcrypt=0)
http://pastebin.com/QVJkHMzy
As you can see CRDA thinks I'm in China, which is not true. I think
that information is taken from some kind of chip memory (log talks
about EEPROM), and I've no idea if it's important to change that
information and how to do that.
Connection is unstable and disconnection happens about every 30 seconds.

ath9k_htc (debug=601, nohwcrypt=0)
http://pastebin.com/Z045ZDFQ
Same situation as before but with huge debugging infos

When enabling nohwcrypt connection seems to be stable, but I've to
guess that doing encryption entirely in software decreases overall
performances.
Since hw encryption seems to introduce problems, could it be a firmware
related issue?

Thanks a lot

Yes it seems to be. Please apply the following firmware patch
which is yet to be intergrated into git tree.

It could not be considered a real test, but for what I've see in those
minutes it works (with hw encryption  enabled)

Thanks a lot.
I'll try that also on different networks (b-only, b+g and n-only) in
next days and will report..
