with accesspoint i have (ap5131) 2.6.36 worked (seemed to) at the
beginning; other test by other people with different AP (wireless
switch RFS6000 + access port AP650) showed up the problem i initially
posted here: "not associating to access point or better associating then
de-associating for 'reason 4: Disassociated due to inactivity'"; then i
looked at Changelogs for 2.6.37 and i noticed that there were many
changes into cfg/mac80211 then i migrated to kernel 2.6.37; same as
before with my access point it worked while with wireless switch not;
(to be honest sometimes also to me happened associations problems but in
manner not 'deterministic' i.e. coming back to 2.6.36 (same situation
that worked early) it stopped work with same deassociation issue; so i
try to go back to 2.6.35 and it started to work again to me, so i gave
this version to people with wireless switch, but there it still not
worked, the module doesn't associate for some different inctivity
reasons like 'reason 2: Previous authentication no longer valid', if the
wireless switch's profile is open or 'Reason 15: is "4-Way Handshake
timeout"' if wpa2 is active; so i can really 'state' that (unlickly) i
saw one kernel working all the time neither by my side (with people
with wireless switch at the opposite no one kernel ever worked!)

i'll try with kismet or wireshark (keeping my finger crossed....,but
the fact that problems are intermittent make me feel bad....)
