Comment 27 for bug 1098225

bcmwl-kernel-source_6.30.223.30+bdcom-0ubuntu1_amd64.deb works for me too (better than 5.100.82.112+bdcom-0ubuntu3_i386, which had delayed network detection with linux 3.8.0). It does not compile for the current lowlatency kernel (3.8.0-22-lowlatency) because of a GPL-only export symbol. The "fixed" version (just declare it GPL...) works also on that kernel.
