Hello! I also have the same hardware, and I have this same problem. There were some attempts to discuss the error in this report: https://bugs.launchpad.net/ubuntu/+source/broadcom-sta/+bug/1289996 (now with status "invalid")
With some tricks, in Ubuntu version 12.04 to later, works. Since Ubuntu version 14.04 is not possible to avoid this error. I returned to the investigation of this error, which already has a long time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1422637 Title: Broadcom BCM43142.
