please provide the lspci output ? – Raja Apr 27 '13 at 15:17

Because the program asks your password, you can be sure that your wireless card is working. Check with

ip link

You should see eth1 (or wlan0) with 'state UP'

There are different solutions

  • Reboot

  • sudo rfkill your wireless card (disable an re-enable it)

  • Power off your WIFI-router. Wait some time and restart.

I had the same problem when I upgraded to 13.04. I don't remember what solution I chose. Maybe all.
