This is the second times it happens to me. Both times, scenario was the same:

  • running ubuntu
  • wireless connection were disabled
  • my computer stopped brutally (no battery or hard reboot)
  • when I reboot, there is no wireless connection option anymore (windows and ubuntu)

First time it happened, I had to send my computer to technical service and they changed my motherboard. But I can't believe there isn't an easier solution.

My pc is a DELL inspiron M301z with ubuntu and windows in dual boot.

As I expected, the answer was easy : the wireless card was disabled in the bios setup.

Hope this will help other people.
