Well one thing i noticed is that i had the same exact problem with my itouch too, check on your router if the is a S/N Code, there might be a barcode or a W/P, if theres a barcode look for the W/P label, that is you password unless you changed it, i believe if you changed it you can go to the network connections settings on your computer and see if it's changed, if not, its the same W/P password on your router, i still had problems though after i connected but i think it was because we had a very, very old router.
