Great question, john! For this model, the Wi-Fi connection allows the refrigerator to be connected to Samsung's SmartThings app. This app offers lots of great features like monitoring the temperatures, ice maker, and even checking if the door is open, all from your smart phone! You can read more about all the great SmartThings features beginning on page 38 of the user manual (https://bit.ly/3jye8B2). ^Jecca
