These APs are truly bad. Hacking linux into it (DD-WRT) helps a bit, but 
wireless often seems to fail *completely* at times.

The deauth reason code is usually 6 or 7.. IIRC, it is 6: Class 2 Frame from 
Non Authenticated STA. The AP just forgets you're associated. However, I 
think that was from when I had a v3 WRT54G.

I made sure the old adm8211 softmac stack had a very good set of printks to 
report these sort of things. :) Many APs do funny things..
