Okay, I have never had a problem with using my touch on my home wi-fi network, but suddenly it won't work at all! It says it's connected, but when I try to look at a web page, it can't locate the server. Installer won't refresh resources, basically, even though it says it's connected, I can't access anything. Suggestions? I've tried turning wi-fi off and on. Renewing the lease. Resetting network settings. Help!
