Comment 41 for bug 85099

According to Thom the recommendation:In fact, this is no bug in bcm43xx-fwcutter and support has not been dropped for older cards. The new bcm43xx driver, which went to Feisty, requires a 4.x firmware version. In order to get one, download the latest bcm43xx-fwcutter from http://developer.berlios.de/project/showfiles.php?group_id=4547 and look at the README. At the bottom, there is a link to a 4.x firmware. Get it and compile the bcm43xx-fwcutter version that you just got (the one in Ubuntu is too old) running make. Then extract the firmware via ./bcm43xx-fwcutter FWFILE and copy the .fw files to /lib/firmware. Reload the bcm43xx module (sudo rmmod bcm43xx && sudo modprobe bcm43xx) and everything should work fine then. I'll try to get an exception in order to make the recent fwcutter version available in Feisty.
Doesn't seem to fix the issue, back to the drawing board?
