Evidently, the problem is internal to your ipod, unfortunately. It can be a connection problem with the antenna circuit which sits in the upper right hand corner of the unit, or possibly with the wifi electronics. In either case , this is not considered user repairable. I would advise you to have it serviced by taking it to an Apple store or shipping it by mail. Apple has a fixed price exchange program where you would receive a refurbished unit in exchange for yours. In that regard, I'm including a link whcih will give you the pricing. Just select the country in which you live , then select repair pricing , then expand all.
