Public bug reported:

I am doing a live USB boot (Ubuntu 14.04.2 LTS release amd64) on a
Macbook Air (6.2).

The WiFi is not recognised. If I attempt to install the STA driver by
selecting 'Broadcom 802.11...' in the 'Additional Drivers' of Software
update then while it claims to be using the driver, the wifi is still
not recognised. lsmod confirms no 'wl' driver is loaded.

I have got WiFi running with the following steps in the terminal:
  cp -a /usr/src/bcmwl-6.30.223.141+bdcom . && cd bcmwl*
  patch -p1 < patches/0009-add-support-for-linux-3.10.0.patch
  patch -p1 < patches/0012-/home/james/0012-add-support-for-linux-3.16.patch # Attached
  cp lib/wlc_hybrid.o_shipped_x86_64 lib/wlc_hybrid.o_shipped
  make
  modprobe lib80211
  modprobe cfg80211
  insmod wl.ko

I'm guessing that the bcmwl-kernel-source package on the 14.04.2 install
image doesn't work with the kernel on that image.
