Comment 92 for bug 318942

Just found that older custom kernel with restricted driver package tutorial hack on the net but I did not try it. http://ubuntuforums.org/archive/index.php/t-441013.html

I think the wireless network stopped working (broadcom closed source) because of the restricted driver modules -11 package does not fit to the custom -12 kernel. But works with the -11 custom kernel because the original kernel is also -11.

Solution would be a hack of the precompiled package to work the the custom made kernel.
Or create a decent package of the restricted-driver-modules for the custom kernel by Andy.
