I have one of almost every version of atheros part and I do not see the problems you allude to; not that you've provided any useful info here.

I just fixed a couple of adhoc mode problems yesterday that are likely unrelated. I had a network of 4 machines setup in adhoc mode; 2 ath freebsd systems, one powerbook with tiger, and one freebsd system with wi. All were in the same room. I saw no problems in several hours of testing. When the 11b station was not in the network I routinely got 28Mb/s for tcp netperf between stations (this is 11g). I am not saying the code is perfect. I'm aware of a couple of issues that I'm working on but in general I am not seeing significant issues with ath devices. If you or anyone else wants to help fix problems you need to provide useful information such as the mac/phy version for the part and the output from 80211stats and/or athstats. It also helps to enable debugging msgs; usually at the 802.11 layer using 80211debug. Sam
