Am Having issues with My Wireless 1 My laptop had dual boot windows 7 and Ubuntu 13.04 I upgraded to windows 8 and after the first 2-3 reboots all was working well in windows and ubuntu then my wireless in ubuntu stoped working saying "wifi is disabled by hardware switch" the hardware switch has no effect I removed network manager installed new firmwares and still nothing the wifi was not working in a moment of testing I installed wifi radar and this can detect the wireless signals and at one point it connected but still Network manger still says disabled.

My Laptop is a HP Pavilion dm4 2070us with Wireless Centrino N 1000

I have updated to 13.10 thinking it would fix it but still nothing

You've probably pressed the airline mode key by mistake. It's to prevent wireless use on airplanes.

On my machine it is the F12 key with a vertical line and samller brackets around the top half of it (supposed to be a transmitter/receiver image). Find yours and press it. It's a 'toggle' switch so pressing it by mistake is a frequent thing (at least for me!). But easy to correct.

Pressing that has no effect –  Peter Kihara Oct 18 '13 at 13:15
