Wireless DW WLAN Card not working. Wireless adapter doesn't exit?

I'm gonna start this off with I don't know too much about computers.

I haven't installed anything new lately, nothing that would affect the wireless, but my wireless suddenly stopped working. My wireless has been working successfully for the past 2 years no problems till now. I have a Dell Latitude E6410 my computer is running Windows 7 32bit. When I open up  the DW WLAN Card Utility it says "There are currently no wireless adapters available and enabled. Please enable any available wireless adapters before accessing this configuration utility.  I tried reinstalling drivers for the wireless but my computer says "no compatible hardware found".

Also the under the wireless adapters section of Device Manager there isn't an adapter for wireless, but there is an unknown device.

Here's a View at my Device Manager

I've tried to use computer restart magic but no luck there.

Also, my computer is running on a university network. My roommate's wireless is working fine. Also I've already system restored to a point where I know it was working, no luck...

Please Help!!
