Step by step

1. 

   Switch Auto Wi-Fi off

   In Settings, Wi-Fi, tap the three dots at the top right, then More settings. Auto Wi-Fi turns Wi-Fi on near a network you connected to before. It was off on ours.

   Done

2. 

   Check Wi-Fi Assistant

   In Settings, Wi-Fi, tap Wi-Fi Assistant. Its only switch on ours was Auto-connect to the best Wi-Fi, off.

   Done

3. 

   Switch to mobile data?

   There is no such switch on ours. The only related search result was Mobile data always active, in Developer Options.

   Done
