Ever since iOS 5 I have been having plenty of trouble with Wifi Sync between my iPhone 4S, iPad(3rdgen), and my windows 7 machine. All are running the absolute latest versions and have had this problem persisting across numerous restores, reformats, etc etc... I am starting to wonder if this is a problem with bonjour or my router. Regularly I will walk to my computer and find a LARGE stack of iTunes errors, all pertaining to iPhone/iPad sync fails. are there some settings I need to adjust?
