FOUND THE FIX!! 1.) Go to SETTINGS next to your networks name there's a blue arrow click on that. 2.) Now turn ON auto-join 3.) Turn OFF auto-log in 4.) It Works!
I have this problem too, I saw some people with the same issues on the apple forum but they've been wiped off in the past hour. I think apple has sabotaged older ipods. All the issues occurred in the past few hrs.
