Broadcom BCM4331: “device not ready firmware missing” error






I can't seem to get my wireless card working on my Mac Mini 5,1. Lspci returns: 



03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)


But running "additional drivers" doesn't detect anything. The nm-applet menu reads "device not ready--firmware missing." What can I do to get this to work?



Note, this is with 12.04.1, so many of the previous discussions (for 11.10, etc) probably don't apply here.

I got it working by following the instructions at https://help.ubuntu.com/community/MacBookPro8-2#Wireless, namely:




There is no official support yet in Ubuntu 12.04, but you can get it
working with the following repository.



sudo add-apt-repository ppa:mpodroid/mactel

sudo apt-get update

sudo apt-get install b43-fwcutter firmware-b43-installer


For Precise, the Compat module should also be installed



sudo apt-get install linux-backports-modules-cw-3.3-precise-generic


Edit the /etc/modprobe.d/blacklist.conf and add the line:



blacklist ndiswrapper


Create or edit the file /etc/pm/config.d/modules and make sure the
wireless modules (b43 and bcma) are blacklisted:



SUSPEND_MODULES="b43 bcma"


Reboot and the wireless should work.
