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

Well, is it TX or RX speed? Or both?
2 megabytes/sec sounds like it's doing 11g only, but you've shown it's
currently selected MCS6, so it should be TX'ing fine.
It would likely be nice if there were some better tools for trying to
log some aggregate, real-time statistics as to what's going on, both
TX and RX. It's quite likely something that's easily fixed.
I don't have a Linux box handy, but the output of the phy debug
statistics would be nice. Eg, stuff like:
* The output of the rate control logic;
* The output of the packet errror counters.
I also wonder if ubuntu is shipping with the 'nohwcrypt' option enabled.
Would someone please give me a hand and help Alexander here find out
the above? That way we can try and move forward.
(Note: with ar9285 issues it seems ath9k is either having issues with
antenna selection and/or crypto handling. I don't know why the latter
is occuring and I don't have time to go digging into it. I do know the
driver can and does do full rate MCS7 TX though. I've done it myself,
both Linux and FreeBSD.)

looks like a throughput regression
kindly check whether there is any improvement with

Hi,
<2Mbyte/s is for receiving from a samba Server.
for sending its a little more like 2.5 Mbyte/s.
with "options ath9k nohwcrypt=1" in /etc/modprobe.d/ath9k.conf I get
about 2.1-2.2 Mbyte/s receiving
don't know if thats what you wanted
