Hello,
I'm experiencing some inconsistencies with bwi driver. I just did a fresh
new -current install from snapshots, downloaded firmware following
instructions from bwi(4) man page and successfully associated card to my
wireless router (debug logs below). Card seems to keep the connection for
only a few seconds and then immediately becomes unresponsive, sometimes it
is unresponsive right from the start - it might again show some temporary,
short response randomly after re-associating. I wonder if this has something
to do with my card (ASUS laptop, more details below) as bwi(4) man page
mentions that some chips are incorrectly calibrated. After doing some search
on the net I discovered that some people with Apple laptops also seem to
have the same issue. I'd be very grateful guys if you could drop me some
suggestion how to track this or perhaps some thoughts about a possible
solution as I'm currently trying to learn more about internals and would be
glad to give some help or even contribution as well. Thanks!

Driver messages with 'debug' enabled. Here I'm basically doing: ifconfig
bwi0 nwid XXXX wpakey XXXX debug; ifconfig bwi0 up; dhclient bwi0. Most of
the time dhclient gets the IP but connection lasts for a few moments and
packets just seem to get "lost". After it becomes unresponsive I'm starting
to get these lines:
..
bwi0: received probe_resp from c8:3a:35:07:7a:78 rssi 19 mode 11g
..
(many more with different 'rssi' and addresses)
