Re: ubuntu 12.04 issues with wireless
I have the exact same problem. I have a MacBook Pro 8,1 Late-2011 that has the Broadcom BCM4331 wireless card and tried Ubuntu 12.04 x86-64 beta-1 in Live USB.
The Network applet in the top panel says
device not ready (firmware missing)"
/etc/modprobe.d/blacklist.conf has "blacklist bcm43xx" although says "FATAL: Module bcm43xx not found."
lsmod | grep b43
says unable to locate package.
sudo apt-get install firmware-b43-installer
Very frustrating that everything EXCEPT wireless works out of the box on my MacBook - touchpad with gestures, keyboard hotkeys, awesome battery life! Especially when linux kernel 3.2 supposedly added support for BCM4331.
Acer-AOD250 N280-1.66GHz 1GB-DDR2-533 160GB-HDD Ubuntu-10.04 x86

None of us were born knowing to use Windows. We just got used to it - unfortunately!
