Phantom 3 4K controller won't stay logged in to WiFi

My Phantom 3 pro works perfectly after connecting the controller to wi-fi. Problm is, the controller doesn’t remember the wifi account and it has to be reconnected every time in order to fly. How can I make it connect automatically, as it should?

Are you sure you have a Phantom 3 Pro? The Phantom 3 Pro doesn’t use Wi-Fi.

Actually, it is a Phantom 3 4K, which apparently is an upgrade of a Phantom 3 Standard.

There is no way to automatically connect via Wi-Fi. You’ll need to go through that process every time you power on the drone.
