The wifi on my Dell XPS 13 stopped working yesterday. It connects, and drops the connection a few seconds later. It was working before, the only thing I can think of that happened was a routine system update.

This is the chipset:

01:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)

Any ideas?

Edit: This seems to have been a hardware problem, replacing the wifi-card solved the problem.

  1. Connect to Internet via LAN cable and run apt-get -f install to fix anything went wrong.
  2. Check Additional Drivers for drivers and if you find it already activated; deactivate and activate again.
