Hi,

I have an Atheros AR9285 in my Samsung Notebook and run Kubuntu 11.10 
and Win7 on it.
While using Win7 i get speeds of about 8 Mbyte/s
When using Kubuntu I get only speeds below 2 Mbyte/s

I tried the daily driver of 2 january 2012, but nothing changed.
via wired I get about 8 Mbyte/s, just to show that its not on the server 
side.

Is it possibly to get higher speeds?
it's just kinda sad to get speeds from 5 years ago with new Hardware.

thanks

Here some data:
