OK so here is the backstory. Bought a used Phantom 2 Vision Plus from a well-known retailer. Drone works pretty much flawlessly (flying). I am having a big issue with my wifi connection. It connects to my Samsung Galaxy 5 without a problem and I can use the DJI Vision app. However, when I take off and fly maybe 60-80 feet into the air I lose my connection with the wifi. I can still fly and it continues to record video but I have no control over movement of the camera and I lose ability to see battery level and satellites connected within the app. I have gone so far as to take the range extender and leave it on the ground with the Phantom and walk away connected with the app and continue to view the camera and it stays connected as long as the extender stays with the drone. But once I move away with the phone, app, and range extender more than about 60 feet I lose the wifi connection. Any thoughts on what may be causing this? Is there any way to test the wifi module inside the phantom? I cant find any schematic to actually see or check wires for. Also is there any way to check maybe the internal antenna of the phantom? Any help would be greatly appreciated!!
