On thinkpad there is a real hardware switch to turn on off wifi, have you checked ? – Dukeatcoding Jun 27 '13 at 8:00
@Dukeatcoding mine is ideapad and this doesn't have hardware switch. – Prince Jun 27 '13 at 8:17
What does this report? rfkill list all – chili555 Jun 27 '13 at 13:56

On my G570 laptop, their is a small tiny black switch which acts as the hardware switch. This works, and needs to be moved to the right to turn the wireless on. I don't know whether this is the case for the G580.

Sorry forgot - it is on the front, just to the left of the touchpad, and to the left of the indicator lights – Wilf Jul 26 '13 at 12:01
