Wireless just stopped working

[kerryh8er04]

So the other day I was playing with some settings on my wireless card so that I could use a Ad Hoc network... I got it set up but decided I didn't need it. However after doing this set up, my wireless hasn't worked at all. Windows says the card is on and is in good working order however the wireless light on the screen no longer lights up. I am at a complete loss for what to do. As far as I know I have undone all of the settings that I changed for the Ad Hoc thing but still I cannot get my wireless to work...

Any Ideas of what to do to get it working again?
