On my friend's Ubuntu 12.10 (Unity) laptop, there is no longer an option to connect to a wireless network. It used to work. He doesn't know what caused it to go away, but does anyone know how to get it back?

More info:

  • See the screenshots below
  • No wlan things show up when you run iwconfig
  • Laptop is HP ProBook 6550b

@EnesKuray: I updated the question to include the laptop model. But I'm wondering why you believe the hardware might be relevant if the wireless used to work? –  Ian Hincks Nov 19 '12 at 18:44
    
@IanHincks because some wireless devices need drivers that Ubuntu does not come with by default. –  RolandiXor Nov 19 '12 at 20:49

I found this link and it worked for me. I had the wireless work once and the button above the keyboard worked that once. Then I could not find the wireless network adapter. http://www.bigfatostrich.com/2011/10/solved-ubuntu-11-10-wireless-issues/

Thanks for your answer! Can you include a short explanation of the necessary steps from the link? Links go down sometimes and other users can't benefit from your answer if that happens. –  mrcktz Nov 26 '12 at 22:15
