Comment 12 for bug 1454717

OK, i tried this fix on HP240 G4 running Ubuntu 14.04, the fix in some way helps because before do it the wifi doesn't worked at all.
After this fix, all goes so much better but still have some problems: very low-signal, randomly it's hard to connect to router D-link, Linksys and others, and when it finally gets connected, after arround 15min it's drops the connection and start to try re-connect once again.
Finally, do not connects to my ad-doc net from my other laptop (Ubuntu 12.04.5)

Had the same problem several months on my Lenovo G500 with BCM43142 looking for solutions but nothing. This week read a solution on another thread (https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1405074), gave it a try and it worked.

I downloaded the binaries for 6.30.223.271 (from http://www.broadcom.com/support/802.11), uninstalled my current driver, installed the new one (follow the readme https://www.broadcom.com/docs/linux_sta/README.txt) and it stopped the unstable wifi and disconnections. I hope it will continue like this, 3 days have passed and everything is still okay.
