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. 
In general I tend to ignore complaints of the form "it don't work".

Again, nothing useful 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.
