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
