First of all, my problem is quite likely caused by a buggy AP. It is a

I have already reported one bug to Linksys, which they have neither
acknowledged nor fixed! In that case, SoftMAC had to be modified as a
work-around.

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

I don't know why the deauthentication is being sent. The reason is not
logged, which will be my first change in the code. The second place to look
is why SoftMAC reports the network is unknown when the MAC printed is that
of my AP.

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..
