I installed ubuntu 12.10 lest night and I have been unable to get wireless working using the directions here https://help.ubuntu.com/community/MacBookPro8-2/Quantal
When I add the ppa mpodroid/mactel and run an "apt-get update" I get 404 errors for the mactel repos.

I also tried just installing the packages

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

because some bloggers have had success with that... However, that had no effect.

Before I start trying to hand build the drivers and b43-fwcutter like what worked on 12.04 I wanted to come here so I don't end of messing things up.
