lsb_release -rd:
Description: Ubuntu 12.04.2 LTS
Release: 12.04

uname:
Linux 3.2.0-37-lowlatency #37-Ubuntu SMP PREEMPT Mon Jan 28 13:38:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

bcmwl-kernel-source version:
6.20.155.1+bdcom-0ubuntu0.0.1

hardware:
BCM4322 (as part of Macbook Pro 7,1)

steps to reproduce:

1) Install 6.20.155.1+bdcom-0ubuntu0.0.1 from precise-updates.
2) Set network security to open.
3) Connect to the network.
4) expected: successful connection; actual: unable to obtain IP address

Other info:
After upgrading bcmwl-kernel-source to the new version it worked well on two WPA2 secured networks, and then refused to connect (unable to get an IP address, using both dhclient and dhcpcd, while using wicd) on an open network.

I was able to reproduce this changing the network to secure (and getting connected) and back to open (not getting an ip address).

Also tried: reinstalling the package, removing and restoring the module (rmmod wl && modprobe wl), rebooting the machine with similar results. I tried booting into the 'generic' kernel as well, and got similar results.

Reverting to the package 5.100.82.38+bdcom-0ubuntu6 worked properly.

I don't think it's a duplicate of 1097519, as that bug affects BCM4313, but BCM4322 should be one of the supported by bcmwl.
