Public bug reported:

I installed Ubuntu 12.04.1 on this system, then the proprietary bcmwl-
kernel-source driver. It installed version 6.20.155.1. The available
networks are shown on nm-applet, but I can't connect to any of them. For
WPA networks, I get asked for the passphrase, but then the icon just
throbs endlessly and never connects. Open networks don't ask for the
password but also don't connect.

I know the wireless networks are set up correctly as other systems are
able to connect. I used b/g and n test networks, on 2.4 GHz band, both
open and with WPA. the access points are Cisco E3000 (and one Cisco
enterprise AP for which I don't know the model number).

This seems like a regression from the old version of the driver
(5.100.82.38+bdcom-0ubuntu6). With that version, the system is able to
connect to b/g networks only; n networks can't be connected to. But at
least b/g worked :)


This system is primarily used for testing, so don't hesitate to ask for further 
tests, package installs, logfiles or anything that may be of help.
