List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 16 May 2011 11:39:53 -0000 Hi, Just thought I'd post an update here, partially to let people know what's going on and partially so I don't forget. When I run an SR-71A AR9160 STA -> Unex DNMA-83 AR9160 AP in 11n HT40 ShortGI 5ghz mode, with no tx/rx aggregation enabled, I get a good, solid 52mbit/sec TCP throughput. When I run an SR71-15 STA -> AR9160 AP in the above config, it starts at 52mbit and then it falls over time to around 47mbit. The CRC error count on the AP goes up and I'm sure the long retry on the STA goes up too. The SR71-15 and SR71-A NICs are in the same box. If I then switch back to the AR9160 STA -> AR9160 AP, everything is ok. I'm going to do some more debugging to see what's going on but it's possible there is something subtly strange with the TX power config/calibration on that unit. I'll have to do some further digging to see what's up. I haven't tried the SR71-12 (2.4ghz AR9220) yet, nor have I tried the SR71-15 doing RX aggregation in hostap mode. If you're using an SR71-12 or SR71-15 with -HEAD then please let me know. I may need some verification of fixes. Thanks, Adrian
