wireless connection won't connect

[ChaoZ]

I have a Linksys wireless-g card and router, it keeps saying no connection found in range. This is my sister's computer. It was working just fine yesterday, but wouldn't work right now. Any help? This sometimes happens and it's really pissing me off. I don't even know how I managed to fix it the other times.

Edit: My main computer can't connect to here: http://192.168.1.1/

Delete the connection and start over. Are you using windows to configure it or the linksys software?
