Yeah... the b43 driver somewhat worked with raring but has always been
very unstable for me. Additionally it does not support the 5GHz band on
the BCM4331 chip which would eliminate it as an alternative to the
bcmwl, even if it would become more stable.

Title:
  bcmwl-kernel-source 6.30.223.30+bdcom-0ubuntu1 fails to see 5GHz
  networks and is unstable on 2.5GHz

Status in “bcmwl” package in Ubuntu:
  Confirmed

Bug description:
  Hardware: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

  This chip is working perfectly fine on 2.5GHz and 5GHz using version
  6.20.155.1+bdcom-0ubuntu6 of the driver.

  After upgrading to saucy and installing version 6.30.223.30+bdcom-
  0ubuntu1 it fails to find any 5GHz networks and connections on 2.5GHz
  are unstable.

  Downgrading the saucy machine to kernel 3.8.x and bcmwl-kernel-source
  6.20.155.1+bdcom-0ubuntu6 (both from raring) makes the chip work
  again.

  Downgrading just the kernel to 3.8 and keeping bcmwl-kernel-source at
  version 6.30.223.30+bdcom-0ubuntu1 does NOT fix the issue.

  Looking at the changelog its most likely caused by the update to the
  new upstream release.
