I think this may be quite a common problem but... I have been having problems with my iTunes Wi-Fi sync for some time now, the problem is that devices don't show in iTunes, or sometimes they show when they want to. There are 2 iPhone 5s 2 iPhone 4Ss and an iPad 3rd gen that have been synced with iTunes. It seems that the devices only show over Wi-Fi when they want to, if ever. There are various solution online including: Restart iPhone and computer (Tried, doesn't work) Reinstall iTunes (Tried, doesn't work) I am using iTunes 11 and OS X 10.8.2 running on a Mid-2009 MacBook Pro 13". Any ideas? EDIT: it only seems to be my iPhone 5 that isn't appearing, the other 3 appear, no problem. EDIT 2: Sync over Wi-Fi IS checked.
