ok so about a month ago i got my ipod touch soked on a boat. the wifi ceased to work at all and i spent days trying to get it to dry. probably two weeks later it began to work perfectly. now i am having the same problem! it will not detect my wifi unless i am holding it right next to the router and even then it will not connect. i have tried reseting it, restoring it and nothing seems to help. Any assistance would be greatly appreciated.
