Step by step

1. 

   Switch off Turn Wi-Fi on automatically

   Open Settings, Connections, Wi-Fi, tap the three dots at the top right and tap Intelligent Wi-Fi; it opens even while Wi-Fi is off. This is the switch that turns Wi-Fi back on by itself. On ours it was greyed out with the note Turn on Location to use this feature, so it only works while Location is on.

2. 

   Check Switch to better Wi-Fi networks

   This moves you between saved networks when another is faster or more stable. It explains Wi-Fi changing network by itself. It was on on ours.

   Done

3. 

   Check Wi-Fi scanning

   Settings, Location, Location services. Wi-Fi scanning lets apps use Wi-Fi for location even when Wi-Fi is off. It does not switch Wi-Fi on, but the phone keeps looking for networks. It was on on ours.

   Done

4. 

   And Bluetooth scanning

   The same for Bluetooth, just below. Switch both off if you want the radios fully quiet; location may then be less accurate.

   Done

5. 

   Check your routines

   A routine in Modes and Routines can also turn Wi-Fi on, for example at home or at a set time. Open Settings, Modes and Routines and tap the Routines tab at the bottom.

   Done

• The phone switches to mobile data Samsung says Switch to mobile data moves to mobile data while Wi-Fi is unstable and back when the signal is strong. Turn it off in Intelligent Wi-Fi. Source: How to optimize network connectivity?
