Title:
  bcmwl-kernel source: fix for null pointer crash

Status in bcmwl package in Ubuntu:
  Incomplete

Bug description:
  The bcmwl package as of now misses one patch for a bug that occurs
  with BCM43142 and possibly other broadcom chipsets that will look like
  random disconnects, poor wifi signal and kernel warnings, See also
  #1379524.

  Adding the patch is a fairly simple process:

  * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches
  * add the following line to  /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf
  PATCH[7]="0014-null-pointer-crash.patch"
  * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom /usr/share/bcmwl x86_64 $(uname -r)

  This has fixed the issue for me. Edit: I just wanted to add that I did
  not write the patch; I merely downloaded it from a paste that was
  linked from the respective AUR package.
