Bug#622753: ath9k: Connection over wlan slows down and dies
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!

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?
