My wifi signal disappears and cant access Internet
My Ipod's version is 3.1.3. When I turn on wifi and choose a network in list below. My wifi signal not appear, even the Ipod connected to Network (but can't access Internet). Then I look for the network's information, but it blank, everything is blank (Ip address, Subnet mask, router...). And the safary browser cant access Internet, it notices: "The error was: Operation could not be completed. Invalid argument.". I reset the ipod, but it still be.
So someone could help me find out what's wrong. I just bought it for 5 months. Thanks
