I have problem with my wifi after resuming from suspend mode. It says "wireless is disabled by hardware switch". In my normal boot I just press F3, the Wifi led light turns on and my laptop starts searching for signals. But resuming from suspension, I press F3, Wifi led light turns on but no Wifi signals detected. the message "wireless is disabled by hardware switch" won't change at all. I'm new in Ubuntu. and excuse my grammar.. but my bluetooth seems fine even resuming from suspend mode.
