I had this issue and what worked for me was to connect uo via the usb cord. Switch off sync with Wifi, Clic Apply.
Switch on sync with Wifi, Apply.
When finished disconect from USB cord. Iphone should stay in the left hand panel. Did mine a month ago and has been rock solid ever since.
Hope it helps you.
