The wireless device is shown and it is enabled on Network Manager but no networks are displayed.

This happens often and with no visible reason.

When I turn off the computer, unplug the energy cable, count to ten, reconnect the energy cable and turn on the computer again, the wireless network list becomes available again. If I don't disconnect the energy cable this workaround doesn't work.

This often happened a while ago. My machine does not have a shortcut key to enable / disable the wireless network, I didn't have the "disconnect energy cable" workaround yet, so the solution was restart to the Windows (dual boot), enable the wireless network on the control panel and back to Ubuntu.

How can I have my wireless network working again with out neither of this weird workarounds?

  • Thanks for your answer, but I prefer do not include non official repositories by the security risks. Is there any way to set the device working without include this new repository? – Robinson RK Oct 1 '15 at 19:55
  • This is my repository ;-) If you are afraid, you can install the driver and then disable updates from it. – Pilot6 Oct 1 '15 at 19:58
  • Nothing personal, I will try everything else first. Drivers are a common way of attacking, no matter what OS is. – Robinson RK Oct 1 '15 at 20:36
  • You can install the same driver form github. But it is the same. – Pilot6 Oct 1 '15 at 20:59
