I may have a work around for this. My chipset: 09:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) According to http://help.ubuntu.com/community/WifiDocs/Driver/bcm43x I am supposed to install bcmwl-kernel-source, which is supposedly installed already, per apt-get and synaptic... so, i reinstalled it. ~$ sudo apt-get --reinstall install bcmwl-kernel-source Log started: 2011-05-26 10:04:47 Selecting previously deselected package bcmwl-kernel-source.
