Comment 11 for bug 1160471

Hi Adam. According to lspci, I've got a "Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)." When I had problems with the v6 bcmwl drivers, one of the first things I tried was the brcmsmac ones to see if there had been an improvement since the last time I tried a few years ago. Unfortunately, the brcmsmac driver was unusable. The signal was showing as extremely weak, even when I was stood right next to the wireless router, and even then the connection was regularly cutting out. The bcmwl v5 drivers that come with Quantal work pretty much perfectly so I'll stick with those. I followed the instructions on ask ubuntu here

http://askubuntu.com/questions/286734/how-to-downgrade-broadcom-wireless-drivers-bcmwl-kernel-source

and have placed

Package: bcmwl-kernel-source
Pin: version 5.100.82.112+bdcom*
Pin-Priority: 1001

within

/etc/apt/preferences.d/bcmwl-kernel-source

to ensure that ubuntu doesn't keep trying to upgrade them back to v6. I think this is what Ubuntu should be doing as a matter of course for all people with 'older' wireless cards that don't work with the newer broadcom drivers.
