[ath9k-devel] TPlink TL-WN822Nv2 drops out connections randomly on Arch Linux with Kernel 3.12.1-3

[Oleksij Rempel <linux@rempel-privat.de>]

Finally i found a router to reproduce this or similar issue. It is dlink
dir-615 H1... (there is much more problems with it)
In my case it is ath9k-htc firmware issue, so it will take some time to
debug it.
