Frequently I get a warning that I cannot download live maps because the WiFi doesn't have Internet.  Duh... the WiFi of my RC doesn't provide Internet service.  LOL  How does one connect to the Internet to get maps & be connected to the RC to avoid these warnings?

"Wi-Fi Network not available. Loading satellite map requires more cellular data."

You can cache the map previously. Here's the route: launch DJI GO 4 app----Enter Device---upper right "…" icon----General Settings----Cache Map in the Background.
