Comment 0 for bug 1415880

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-
* add the following line to /usr/src/bcmwl-
* run: /usr/lib/dkms/common.postinst bcmwl /usr/share/bcmwl x86_64 $(uname -r)

This has fixed the issue for me.
