This has happened to me in the Physics building and the CSS building. I haven't been using my laptop in any other place long enough.
I was using the older Debian Lenny packages for wireless-tools and wpasupplicant and thought this was the problem and upgraded to the versions in Debian Testing, but the result is similar. Like I said, I've had issues with my broadcom chip before, refusing to connect to certain WEP/WPA wireless networks known to be very weak. So perhaps the threshold explanation is the best, although I find it weird that so many others have this issue. Andres Cimmarusti http://terpconnect.umd.edu/~candres/
