[ath9k-devel] Tplink TL-WN822N drops out connections randomly on Arch Linux with Kernel 3.9.4 (Mark Lee)

["Peter Vágner" <pvdeejay@gmail.com>]

Hello,
I am afraid I don't know how to do this.
Do I have to recompile the whole kernel testing each commit or should I 
just recompile the driver or even track firmware changes?

Can you please point me to somewhere where I can read on how to proceed?

Greetings

Peter
