Thanks!
Alas, I don't think that's it.
I did "sysctl net.wlan.0.debug=0xFFFFFFFF" - I guess that is the
slegdehammer approach in absence of wlandebug (couldn't find that - I
optimistically installed only X-User).
The following seem to be the transitions (output of dmesg | grep
newstate | sort | uniq):
ral0: ieee80211_newstate: ASSOC -> RUN
ral0: ieee80211_newstate: AUTH -> ASSOC
ral0: ieee80211_newstate: INIT -> INIT

And here's an excerpt of dmesg | grep ral0:

Anything wrong with this (the beacons from my AP?)
