Re: [ath9k-devel] Packet loss regression with Atheros AR9280

[Jan Sundman <jan.sundman@aland.net>]

Hi,

I'm not sure whether you have found a solution to this issue yet but I
thought that I should share my findings. I'm running Arch linux on my
laptop which have the AR9280 and I saw massive packet loss as well.

I noticed however that this _only_ occurred when the laptop was on
battery power. So it seems to be due to some power save functionality
for the card.

"iwconfig wlan0 power off" seems to fix it so I added this to my startup
script and this fixes it. This is of course not a optimal solution but
may point you in the right direction on fixing the problem.

Br,
