What does the Network connection icon on the control panel indicate?
The Network connection icon indicates that the refrigerator is connected to a network. If the Wi-Fi icon flashes, it is recommended that you connect your refrigerator with the SmartThings app to control and monitor it remotely. The refrigerator supports both Wi-Fi 2.4 GHz with IEEE 802.11 b/g/n and Soft-AP protocols (IEEE 802.11 n is recommended). (Page 24)
