I'll also try the b43 driver again, but it didn't work for my [14e4:4315] BCM4312 in the past. Guess it's worth a try though.
So I enabled logging with -d but I don't understand the cause of the problem from this log (last 500 lines attached). To me it looks like the laptop gets disassociated, disconnects, scans again and fails with a timeout. My problem is that I don't know how it's supposed to work.
Which driver was this? The first thing I noticed is that the driver gives reason 0 (no reason) for disconnecting (it isn't even reason 1, which would mean "Unspecified"). After disconnecting, it fails to receive any scan results. I am really out of ideas, but this looks like a driver problem.
This was with the broadcom-wl (proprietary), but today I tried with the b43 (free driver, but same proprietary firmware) with the same symptom but different log messages. The definitive difference is that it tries to scan over and over again. The log is full of that, so I've yet to get a reasonably useful portion out of that log. I'll try to start with a clean log tomorrow. I tried at home with my neighbors wlan where it worked for at least 45 minutes (then he turned it off), but I don't yet know whether this was simply due to a longer leasetime or something similar. Does anyone know of a live-CD which contains those drivers? This way I could likely rule out a problem with Arch. I'll try to get a useful log tomorrow and maybe I can test some more with my neighbors wlan for comparison.
