@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.

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.
