I opened xdiganose and it told me to go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware in order to download and install the wireless driver. I followed the instructions for Ubuntu and it aborted the installation saying something about an unsupported device (I should've saved the output, I'm using a late 2011 13" Macbook Pro.) Now when I try
sudo apt-get install firmware-b43-installer I get this:
Reading package lists... Done Building dependency tree Reading state information... Done firmware-b43-installer is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 338 not upgraded.
What do I do?
