I've got here a notebook running elementary OS. There's been an update some days ago that apparently disabled its WIFI completely - it doesn't show any networks and I can't connect to anything.

I've already done the procedure described here, downgraded the packages libnl-3-200, libnl-genl-3-200 and libnl-route-3-200 and restarted. Yet it still won't work, it seems like something else causes the problem. I can get a connection via cable but this cannot be a permanent solution. Any clues?

I fixed it: wifi adapter is a Broadcom BCM4313. First I disabled it in Software Center -> Edit -> Software Sources -> Additional Drivers. Then I used

sudo apt-get purge bcmwl-kernel-source

to get rid of the driver. And

sudo apt-get install b43-fwcutter firmware-b43-installer

to install a new one. After a reboot it worked again.

  • Thank you very much for your answer. I had the same problem and ran your commands on elementary os. The wifi is working perfectly after a reboot ! Sep 7, 2016 at 18:16
