Comment 34 for bug 1173761

I was able to successfully build this module in kernel 3.8.0-27 per comment 29 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173761/comments/29 on 3.11.0-031100rc3-generic).

        $ sudo dkms build -m b43b1 -v 6.30.223.95

        Kernel preparation unnecessary for this kernel. Skipping...

        DKMS: build completed.

However, I could not remove the existing wl module (using "sudo rmmod wl") because Ubuntu/Linux kept insisting that the wl module was in use. (This was the case even if I disabled wreless from the BIOS). I even tried "sudo rmmod --force wl", but it did not work. Nevertheless, I proceeded to install the new module and it worked after a reboot.

However, I want to point out that this also actually fixed a different bug in 3.8.0-27! I was unable to shutdown or restart the machine. It would just hang during the shutdown process. This is the bug: https://bugs.launchpad.net/ubuntu/+bug/1176028. After installing hybrid-v35_64-nodebug-pcoem-6_30_223_95, my computer shutdowns and restarts normally. I am mentioning this because the wireless fix (or something included in the fix) may be related to bug 1176028.

Just to confirm everything is workign smoothly, I did a fresh install of 13.04, updated all packages, and then aplied hybrid-v35_64-nodebug-pcoem-6_30_223_95. Both bugs #1173761 and #1176028 seem to be fixed.

I could only test Wireless 802.11n, since I do not have a 802.1ac network. Also, I can not verify if the 5Ghz or the 2.4GHz band is being utilized. Finally, Bluetooth, included with the Broadcom 43b1 device, still does not work.
