I've got a Thinkpad X220 and have experienced a similar issue. My
machine uses the iwn(4) driver, but I have also seen the same behavior
with a cheapo USB wireless dongle that I plug in. This is mainly useless
information, but here is what I am wondering: does this problem occur
for you when you connect to other access points? My connectivity issue only
crops up at my office's access point. Things work great at home and on
the bus. You may want to try and connect to some other public wifi networks
and see if the problem is the same for you. I also noticed that I could
*CONNECT* to the access point fine, but only ARPs would make it to my
machine. Maybe do some tcpdump work and see if your problem is similar.
I haven't really spent a whole heck of a lot of time troubleshooting my
own problem because I can connect via a wired connection. However,
hopefully my experience gets you headed in the right direction.
