I have a strange problem trying to wifi sync my iphone 5 to itunes on my imac. I have the latest verion of itunes, ML on the imac. All connected to my airport extreme base station. When I wifi sync my ipad, there are no problems. However when I try to wifi sync my iphone 5, the sync begins just fine, but after a short time, the imac loses its connection to the airport extreme. It does it everytime and only with the iphone 5. I have rebooted the router. Rebooted the imac, and restored as new on iphone 5 a few times, and the same problem occurs everytime. Why the imac disconnects from the router when trying to wifi sync iphone baffles me. Syncing via the cable works fine with no disconnection. The iphone does not lose connection to the router, while the imac does. Really bizarre.
