Ok so when I connect to wifi, in the settings menu, everything looks good. It says "Connected to home wifi", looks normal to me. Back on the springboard, at the top of the screen where there is usually a logo for the wifi signal, there is nothing. When I try to use safari, installer, etc, it doesn't work. Basically, my iPod thinks it is connected to wifi, but it's not. What is the problem? How do I fix it? Thanks.
