Public bug reported: 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.
