Just got back my Phanton 2 Vision from repair.  If I reset the wifi connection i see the phantom and can connect to it.  As soon i I bind it (and I get a successful connection)  I lose the Wifi Connection .  Am i doing something wrong

My first suspicion is that another WiFi signal that is stronger is causing a problem.  I have a dual frequency WiFi router that sometimes gives me a problem so I make sure I'm outside when I'm trying to connect.  Another suggestion is to set the Preview Quality to 320x240@15fps  (this does not affect the quality that the camera is actually set to, only the preview image)

My 3 year old daughter was binding because she ate too much cheese - I have been giving her prune juice and that seems to be working just fine.

In your case, just start restarting your phantom then controller and wifi randomly and its eventually gonna work -
