Media Disconnected, I'm lost.

Hi,

My mother went to connect to the internet last night but her computer would not connect to our home wireless network. I've tried all of the troubleshooting methods prompted by her computer, but with no success. I pulled up her computers information and noticed that it said the media was disconnected. I tried to turn the wifi on and off on her computer (f2), but the red X remained on the connection icon. I'm at a loss for how to fix this. The other computers in our home are connected, just not hers. I'd greatly appreciate any help you can offer to help fix this problem.
