You need to install dkms and broadcom-sta-dkms.

In terminal...

  • sudo apt-get update
  • sudo apt-get install dkms broadcom-sta-dkms
  • reboot

During the reboot, enter your BIOS and disable secure boot.

  • @Pilot6 I looked at the (lengthy text) link that you refer to in your comment, and the answers are from 2011, and don't apply in this case (BCM43142). I recommend a more current/correct dkms driver. Also, when I look at many questions with a "duplicate of" link, the text sometimes doesn't answer the specifics of the current question. Lastly, as much as you may not like this, I don't gain any rep by taking my time researching through all of the possible search hits to determine a possibly appropriate/accurate duplicate answer, and posting that into a comment. – heynnema Feb 19 '17 at 17:15
  • They DO apply to BCM43142. This question is asked a few times a day. – Pilot6 Feb 19 '17 at 17:16
  • @Pilot6 Your link wasn't one of them. Hence my point about "dup of" answers that don't address the specifics of the current question. – heynnema Feb 19 '17 at 17:18
