Compile up athsurvey and run that Typically air is very busy in my apartments. I'm living in multi-store multi-apartment building and here are A LOT of private WiFi networks. Number of them are changing according to time of day (it looks like many people TURN OFF their routers/APs when they are not at home), but at night here are 30-35 networks in 2.4Ghz, and at morning, when I run tests, 15 WiFi networks at range is not unusual.

AC> But we'll get to it, I promise. :) Ok. I want notice, that sometimes (typically AFTER problems with de/re-association) it pick ups higher rates and then I see 125-150Mbit/s UDP stream (it is not full 300Mbit/s, but much better). So, looks like problem is not only with busy environment. AC> If you see any other transmit queue stuck issues then please let me AC> know.
