Subject: [ath9k-devel] Progress on Ath9k HT support on Adhoc mode
Date: Tue, 8 Feb 2011 08:00:38 -0800 (PST) [thread overview]
Message-ID: <233164.93895.qm@web45215.mail.sp1.yahoo.com> (raw)
Dear All
I have added the patch of HT support in adhoc mode by Alex to compat-wireless-2011-01-24 and other patch on iw tool.
My radio card is AR9220 on AR71xx processor board.
The set up is as following:
iw phy phy0 interface add wlan01 type ibss
ifconfig wlan01 up
iw wlan01 ibss join test2 5745 HT40+
There are some issues as follows:
1. It could not get higher MCS. Normally just MCS0
Station 00:xx:xx:xx:xx:ee (on wlan01)
inactive time: 300 ms
rx bytes: 63190
rx packets: 1173
tx bytes: 11724
tx packets: 100
tx retries: 0
tx failed: 0
signal: -51 dBm
signal avg: -52 dBm
tx bitrate: 6.5 MBit/s MCS 0
2. I tested throughput by iperf, tcp, it shows very low throughput, just about 1.3 Mbps. It means the lowest bit rate is in operation, not higher bit rate (such as MCS 15)
Please not that if I change to AP-STA mode, then immediately the higher MCS schemes activated (normally MCS15), so the signal is quite good.
3. Although I just set up 1 point to point link and expected only ONE adhoc station shown in the output of iw dev wlan0 station dump. But in fact it shows more than one stations ?!

The question is whether I set up correctly ? How should I set up ?
Thanks in advance
