My iPod touch isn't connecting to the wifi
When I try to connect to my school's wifi, with my iPod touch, it doesn't work. I have the correct password, username, etc., but when I choose to connect to the wifi, it always has the loading signal, and never actually connects. It doesn't show the checkmark that means you're connected. I also cannot connect to any Internet page cause it's obviously not connected. I've connected to the wifi before, but recently this has been happening.
Any ideas?
iPod touch (3rd generation), iOS 5.0.1
