Whenever I connect to a network, it disconnects in about 3 seconds. It's really annoying and I can't go on the internet with my iPod Touch. It happens sometimes, but it's really annoying and I don't know how to get it to stop. Sometimes when I try to connect back after the disconnection, it tells me I'm already connected but I can't use the internet. When I go on Safari, it grays my screen and says "connecting" Any ideas?
