Interesting.
I'm using the iwl3945 driver. I DO see some authentication timeouts,
which is really weird.. Sometimes to the point where it wont even
successfully authenticate to the card at all and I have to reset.
Very frustrating.
How do I tell whether wpa_supplicant is locking me to a particular
BSSID, and how do I undo that once it's done?

Strangely, it DID just roam as I went from my lunch meeting to
my first after lunch session. But it's still annoying that it
can drop the session so easily/quickly whereas non-NM will gladly
re-acquire the association as I move between areas, even if I hit
an area of no coverage.
