[Other Info]
Original 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.
