So,

It looks like there are 2 or 3 bugs together in this case (maybe ?).

I probably solved just the bug where null pointer was being referenced
(based on a a Debian Bug already solved).

----

Martin,

I need more information than this. The PPA I provided works with Trusty,
Vivid and Wily with 3.13, 3.18 and 4.2 kernels. Can you test other
kernels and provide feedback. Also, about the crash you are facing, can
you attach the crash log ?

Zethan,

Are you using the same model (BCM43142) ?  How come it is fixed
(suspend) and the card does not work ? Please provide better feedback.

Igor,

Are you using the same model (BCM43142) ? Please keep me updated on
status!

----

Unfortunately to follow bcmwl development is not an easy task since they
only provide .tar.gz sources (without any kind of versioning system).
Hopefully with better feedback (logs ?) I might be able to track fixes
in between released versions.

Thank you

Rafael

Title:
  14e4:4365 bcmwl-kernel source: fix for null pointer crash

Status in Dell Sputnik:
  Confirmed
Status in bcmwl package in Ubuntu:
  In Progress

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.
