Flying my P2V in front of my house. Sent it up about 200ft and down the street about 500 ft. Suddenly I get a loss of wi fi warning. My bird is pretty far away. I flick the S1 switch to see if it will reconnect. Nothing happens. I pull down on my right stick and see that she's coming home. Gets all the way back and controls working fine as I land her. I look at my cell phone screen and discover that when the signal weakened as the distance increased the wifi on the cellphone switched to a stronger signal from the wifi in my house. That was why I lost wifi signal to P2V. I thought I had lost connection to my bird, but it was only video. So when I fly outside or any around my house, I unplug the wifi router in the house. Problem solved.
