My Wireless service is not working. What can I do to fix it?

I walked out of my tent (I'm a soldier that's deployed) and came back to surf the net like I always do. only I can't access any wireless networks at all, even though I was using oe 5 minutes ago. Everyone else can use it fine. When I put the cursor over the internet icon, it says "Connection status: unknown the dependency service or group failed to start". When I click "Diagnose why Windows cant find any networks", it tells me "Windows Wireless Service is not activated on this computer" When click on the link to start it, it tells me "Windows cannot resolve the problem Please contact your network administrator or Internet service provider". My Sergeant told me he thinks the wireless in my computer is screwed up. Can anyone tell me what could be wrong or what I can do to fix it?
