[Ryan S Kingsbury <1173761@xxxxxxxxxxxxxxxxxx>]

I can confirm Redstorm's experience. I successfully built the module on
kernel 3.8.0.29 (Linux Mint 15 KDE x64).

The module loaded right away with modprobe and appears to work on an n
network, but it's connecting in b/g mode and the speed has not been
higher than 5.5 MBit/s.

A Dlink  PCIE wifi adapter with 3 antennas can connect under the same
conditions at 30-50 MBit/s.

Title:
  14e4:43b1 Broadcom Corporation Device 43b1 (rev 03) - not supported

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Both during and after installation, 13.04 doesn't support the
  Broadcom-based 802.11ac wifi chipsets.  lspci reports it as "Network
  controller: Broadcom Corporation Device 43b1 (rev 03)".

  Would love to see this worker as it's being a bit of a show stopper for me.
