Wi-fi is not working on my iPod Touch 2G. I am connected to a network, I have full bars, but when I go into Safari I just keep getting a message saying I'm not connected. When I try entering this thread's IP (http://www.ifans.com/forums/showthread.php?t=42331) into the adress bar, I get another message saying it can't find the server. I have no router nor DNS information on settings. Any idea? Thanks a lot!
