AR9285 Wireless 80211n mode get only 25Mbit with Linux 2.6.38.8 and compat-wireless-2.6.38.2-2

AR9285 Wireless 80211n mode get only 25Mbit with Linux 2.6.38.8 and compat-wireless-2.6.38.2-2

[Dane Shih]

hi all

i try to setup AR9285 Wireless  ap mode on fedora 12

but it seem not stable when setup Master mode use hostapd
so ...i upgrade kernel to  2.6.38.8
it's better, no more disconnect

but ap mode in 80211n

hostapd.conf

nterface=wlan0
driver=nl80211
ssid=test
hw_mode=g
wme_enabled=1
ieee80211n=1
ht_capab=HT40+
channel=7
auth_algs=3
ignore_broadcast_ssid=0

throughput only 20Mbits

install compat-wireless-2.6.38.2-2 on linux

/etc/modprobe.d/ath9.conf
options ath9k nohwcrypt=1
modprobe -v ath9k
insmod /lib/modules/2.6.38.8/updates/net/wireless/cfg80211.ko
insmod /lib/modules/2.6.38.8/updates/drivers/net/wireless/ath/ath.ko
insmod /lib/modules/2.6.38.8/updates/drivers/net/wireless/ath/ath9k/ath9k_hw.ko
insmod /lib/modules/2.6.38.8/updates/drivers/net/wireless/ath/ath9k/ath9k_common.ko
insmod /lib/modules/2.6.38.8/updates/net/mac80211/mac80211.ko
insmod /lib/modules/2.6.38.8/updates/drivers/net/wireless/ath/ath9k/ath9k.ko
nohwcrypt=1

i get maxinum speed is 25Mbit
my pc mac acccess another AP maxinum 50Mbit

setup AR9285 Wireless calint maxinum 30Mbit
AR9285 spec is 150Mbits

thanks for any advice

Right, so it's not likely the hwcrypt parameter. I was just checking. :)

I don't know why we should do this, its better to use default hardware
encryption, does it cause any issues.

I'm using

ht_capab=[HT40+][SHORT-GI-40][DSSS_CCK-40][TX-STBC][RX-STBC1][MAX-AMSDU-3839]
channel=1

with this chip and get about 100 MBit/s (kernel 3.0 or 2.6.39)

thanks
kernel upgrade to 3.0
and install compat-wireless_3.0_stable_releases ath9k  driver

[  4] local 192.168.100.254 port 5001 connected with 192.168.100.47 port 49230
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0- 2.1 sec  10.0 MBytes  40.5 Mbits/sec

[  5]  0.0- 6.4 sec  30.0 MBytes  39.2 Mbits/sec

80211n  maxinum throughput 40Mbit

what i should be check

another question
wireless client also get  100 MBit/s

thanks

Well, I'm using the original drivers from 3.0.

Where does this output come from? I don't know it. You could use netperf
for testing the bandwith.

#!/bin/sh

dest="your_srv" # set the servername

while true ; do
netperf -t TCP_MAERTS -H $dest
netperf -t TCP_STREAM -H $dest
netperf -t TCP_SENDFILE -H $dest
done

Start netserver on the server side before you start this script (script
can be stopped with CTRL-C).

I'm using hostapd from hostapd git from 21.04.2011.
