@Rafael: thank you for your efforts to fix this issue.

1)
"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."

"# TRUSTY (fix for future lts-wily kernel)

Trusty needs a fix for 4.2 lts-wily future kernel:

bcmwl, 6.30.223.248+bdcom, 3.13.0-63-generic, x86_64: installed # trusty
bcmwl, 6.30.223.248+bdcom, 3.19.0-27-generic, x86_64: installed # vivid-lts
bcmwl, 6.30.223.248+bdcom, 4.2.0-4-generic, x86_64: installed # wily-lts (fixed)"

I'm confused - I have Linux martin04 3.19.0-26-generic. Is this ok or not? I aquired this kernel by following this: https://wiki.ubuntu.com/Kernel/LTSEnablementStack

If my kernel is not supported I will try a different version.

2)
I'm afraid I was not really aware of the suspend problem which means that my problems can also be linked to the suspend feature which I use heavily. For this reason I never tested how things work with a freshly rebooted system. I'm doing this test right now and will get back to you with the results.

3)
I looked for a log and attached it. It starts with the device waking up from suspend mode at 12:30. Everything is fine for about 30 minutes. The problems start  at 12:57:09.  What is the right term for the "crash" that is happening? It certainly is no kernel panic and the system does not crash or freeze. But afterwards I have very long ping times (>1000 ms) and sometimes connection loss. Sometimes it seemed to get better after disabling/enabling the wifi adapter but I couldn't yet determine any particular pattern.

Best regards
Martin

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.
