Atheros AR8151 v.2 Slow and Unstable Wifi(Ubuntu 14.04)

[geonabro]

I have really low and unstable internet speed over wifi in Ubuntu 14.04...My network card is atheros ar8151 v2 onboard(my laptop is hp pavilion dm4)..

Speedtest in ubuntu 14.04:download speed is under 1mbps(sometimes i can hit 6-7 mbps for 2-3 minutes after some changes on my router settings) and upload is .80 mbps In windows download is 6-7 mbps and upload is 0.80 mbps...

I have tried everything but nothing worked...(I would like to not tell what did i do in order to write down the methods for other user who have this problem)
