I was using my wifi for my iPod. It was working just fine, then my app crashes (ive had the app for a while), and my wifi bars vanish. I reset the router. and the bars came back. But the wifi still won't work on it. Wifi works fine on the laptop, but not the iPod. so, I restarted my ipod...nothing.. I reset my ipod... nothing... I don't want to restore my iPod, but I will if that makes it work.
