my brother's friend has his iPod touch at my house and can't connect to our wifi here. it's password protected and encrypted, and i personally don't remember typing the password into his iPod, but it's displaying the checkmark beside the network and showing WiFi bars, but then when he goes to do anything it says it isn't connected. i might be buying this iPod from him and i want to make sure this is just a software problem and a restore will indefinently fix it. can anyone reassure me about this? i just want to make sure it isn't a hardware problem. PS: already tried rebooting.
