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?
