Subject: linux-image-2.6.38-2-amd64: Connection over wlan slows down and dies
Date: Thu, 14 Apr 2011 14:39:25 +0200
Package: linux-2.6
Version: 2.6.38-3
Severity: important

Since linux-image-2.6.38-2-amd64 the wlan connections on this machine is 1)
slow to connection and 2) slows down to a crawl and 3) dies after some seconds
/ mintes and becomes completely unusable.

Connecting over standard eth0 makes no problems at all. Only the wlan is
affected.

Booting the same machine again with linux-image-2.6.32-5-amd64 turns the wlan
back to normal again.

Has it been established that it's the same bug though?

I had a brief read of that and I'm not so sure. There's so many things that
could impact TX throughput.

I don't have this problem on FreeBSD on my AR9285 NICs and I've ported
almost all of the (non-power saving) related code from ath9k. They happily
sit at the expected TX/RX speeds in 11g and 11n modes.

Is someone who is experiencing the problem able to do some kernel version
bisecting between the known good and known bad kernel?

The bug fix from the report on Bugzilla has been included in stable
release 2.6.38.5 and Debian's version 2.6.38-5.

Does this version fix the problem for you?

Ben.

That would be a different bug, I suppose.

OK, closing.

Hi Ben,
since sunday I am running kernel 2.6.38-2-amd64 (uname -a) (dselect version 2.6.38-5). The wlan module works now almost 
perfect. The "almost" is due to the fact that connection the machine to the android hotspot somehow fails. But all other 
hotspots I used until now work as expected.

Huge thank-you from me!

Yt,

Gunnar
