I thought I'd post a brief update before I put this stuff on (somewhat) hold so I can focus on studies. Here's my current summary from AR9160 tests in HostAP mode. I'm currently seeing around 80-90mbit of TCP RX in ht/40 mode, and around 50-60mbit of TCP RX in ht/20 mode (both 2 stream.) There's an alarmingly high number of missed aggregate frames being missed, so the stream is more out of order than I'd like it to be. I'm able to get around 160-170mbit of UDP RX in HT/40 mode. Again, there's lots of strange missed aggregate packet stuff going on there too which could do with some debugging. The ath driver is still missing TX aggregation and rate control support, so I still can't throw the "enable 11n" switch by default. Unless someone else steps up to the plate and implements it, it won't be done in time for 9.0-RELEASE. I'll look to do it post exams (so July timeframe.) Other than that, I'm just concentrating on diagnostic and debugging at the moment so I can try to identify and fix any other strange radio behaviour. Thanks, Adrian
