Hi I just replaced the camera (crash) and now cannot get reliable, if any. wifi connection. I have run through all the binding procedures many times. Oddly it did show up and connect for a few minutes. Now its not connecting. Green lights are normal. Question: the manual talks about a switch on the camera that must be set to wifi. I don't see any switches but I do see a small hole - presumably for resetting and a silver momentary push button. What does the button do? Anyone have suggestions for getting the wifi to show up again? Thanks!
