Important: The Nintendo Switch console must be used in TV mode to connect online using the wired connection type.
Connect a wired LAN adapter to the Nintendo Switch dock.
Connect an Ethernet cable to the LAN adapter and then connect the other end of the Ethernet cable to your router or gateway.
Place the Nintendo Switch console into the Nintendo Switch Dock
Select Internet and then Internet Settings. The Nintendo Switch will automatically search for nearby Wi-Fi signals.
Once the option is available, select Wired Connection.
Select Connect to the Internet via Wired Connection.
The Nintendo Switch will test the Internet connection. Once the test is complete, select OK.
If the connection test fails, an error code and message will appear,
which can help you.
If possible, we also recommend setting up a wireless internet connection. This enables you to connect online even when your Nintendo Switch is not placed in the Nintendo Switch dock.
