Why do I get "Internet may not be available" message?

If you receive a dialogue message with the title Internet may not be available during commissioning (Fig 1), this is due to the Samsung "Smart Network Switching" feature being active.

The reason for the warning is for you to know that you will not be switched back to mobile data when connected since there is no detected internet connection through that Wifi network. 

Since we are connecting to many devices which are not internet gateways, this message can be irritating and can even interrupt with the bootloading of the devices.

To avoid this system dialogue is to disable this feature. 

Step 1: Go to the Settings menu -> Connections.

Step 2: Tap on Wi-Fi

Step 3: Tap on Advanced located near the top right of the screen.

Step 4: Tap on the switch located next to Smart network switch to enable the function.
