Hi, I am trying to repair an old Phantom 2 Vision I had stored but I am not sure if it used to connect to my mobile without a range extender. The motors are working fine, the aircraft turns on great. The only issue is that I dont seem to find the wifi for my phantom. I've tried power cycling many times. The camera is set to WIFI ON, but still nothing. Do I need the range extender or is it supossed to connect? Thanks!
