actually i don't think it is that - i am seeing the problem
even with the AP and the laptop in the same room.

Just to give a bit of context - my hardware is a Dell X1 laptop
with a 2200bg card operating at 2.4GHz, normally in G mode but
sometimes also with 11b access points.

The lockup occurred with a number of different APs (linksys WAG354,
digicom, hamlet, and another few unknown) and variable signal
strenghts (reporting anything from 34:0 to 85:0), with and without
other AP around).

actually it was between the version of code before it was committed
to the tree (around jan 2006) and the one in the cvs now, and
it was for another bug i.e. the inability to retain the association
to a specific AP (digicom if i remember well).

doing that, in fact... digging in 12k lines of code!
