Wireless isn't working

I have a Dell XPS 15 running Windows 7 64bit.. Today when I was watching a movie on it the wireless went off. I checked and I couldn't turn it back on. I opened up the Windows Mobility Center to see if Wireless was turned on. The option was greyed in shown in the picture below:

I tried installing the drivers again and that didn't work. My router is working fine since I can use my laptop through a ethernet cable and my iPhone can connect fine. A system restore didn't do anything either.

Can someone help me out with any solutions?
