thank you very much.
since you had the same problem before, would mind telling me what is your
throughput rate now?
here I only have avg. 12Mbps, by iperf testing, AR9280( 11na ), HT40, IXP425,
openwrt r20851
YES, that basically solved the problem, I'm sorry being late, Thank you very
much !!!
However, I still got 12Mbps of the throughput rate by iperf testing with
AR9280(11na) on the IXP425 platform, that's incredible, I used to have around
60Mbps throughput, what makes the big difference of th
maybe I should report to openwrt-devel list, but I think it is the problem of
ath9k, caused by using the module minstrel_ht.
the reason I try minstrel_ht is I could only get around 50Mbps throughput rate
by using ath9k for my AR9280 card. some developer said the low throughput is a
known probl
sorry, I mean the station.
I'm not sure where the problem is, I got an avg. 30Mbps( cpu load is <80%)
throughput with my AP( cpu load is avg. 60% ) that built from OpenWrt latest
trunk,
and a 50Mbps( cpu load is 95% on the station ) with a Compex wp543 AP( cpu
load is avg. 70%),
while my AP
if I did the iperf testing in the opposite direction, ( I used to set iperf
client at PC2 and the server at PC1, not it's the client at PC1 and server at
PC2 )
I got a avg. 55Mbps throughput rate, and maximum 60Mbps, it's still not alright
for HT40, even for HT20.
why the CPU load is almost
Thank you.
I did my test again with r19510 the latest one, and I got the avg. throughput
like 45Mbps under HT40, the iw showed:

I use IXP425( CPU 533M, 64M RAM ) platform, OpenWrt r18530 with
compat-wireless-2009-11-21.
As an AP, it worked just good I could see an average throughput like 70~80Mbps
under HT40( the throughput limited by the 100M ethernet in my test
environment).
As a SU, I tested with a compex wp543

Come on, what is an embedded system and what is an optimization?
we might have something wrong with ourselves apparently. the driver wouldn't
complain about is it a desktop or an embedded system.

my case is I only have 20Mbps of iperf test on 300Mbps/HT40, what could
probably be the problem then?
I already attached two pigtails for both the AP and STA.
THANKS A LOT!
AP && STA: OpenWrt 18xxx

suppose we have nothing wrong with the configuration, the driver, the hardware,
regdomain, etc.
and what might be the biggest reason to limit our throughput rate below the
theoretic value? the CPU speed?
Thank you!

ath9k-
madwifi will automatically select a channel as an AP being started, how to
realize this? by any means, thanx!
For example I'm doing with OpenWrt the latest trunk but seems hostapd is taking
over this job and unfinished? or to modify /etc/config/wireless configuration
file?
