Are You Using a Wireless or Wired Internet Connection?
Restart the Nintendo Switch console.
To restart the console, hold the POWER Button for three seconds, and then select "Power Options", followed by "Restart".
Check to ensure the Nintendo Switch console has not been placed into flight mode.
Press and hold the HOME Button for at least one second to access Quick Settings, then look at the flight mode setting. Flight mode must be disabled if you wish to connect to a wireless network.
Set up a new wireless internet connection.
When creating a new internet connection setting, ensure your console is attempting to connect to the correct wireless network and that it is receiving a strong wireless signal.
Move the Nintendo Switch console closer to the wireless router.
If possible, place the Nintendo Switch console within 3 to 4.5 metres (10 to 15 feet) of the wireless router to improve the signal strength during troubleshooting.
It may be helpful to remove the Nintendo Switch console from the Nintendo Switch dock while troubleshooting, and then return the console when troubleshooting is complete.
Power cycle your home network.
Restarting your network devices may resolve this issue if it is related to the devices being unresponsive.
Move any metal objects or electronic devices away from your Nintendo Switch console and wireless router.
Metal objects and electronic devices may interfere with wireless signals. If you have any of these, such as filing cabinets, speakers, power strips, glass, or cordless phones, next to your console or wireless router, move them away.
Situation Not Resolved
If you are still unable to connect, this may indicate an issue related to the network environment or wireless router being used. If you would like to continue troubleshooting potential issues related to the wireless router, contact the router's manufacturer for assistance with performing the following steps:
Updating the wireless router's firmware
Resetting the router back to its factory default settings
Ensure the Ethernet cable is securely attached to the LAN adapter or LAN port on the dock and to the networking device (e.g. router or modem).
Both ends of the Ethernet cable should fit securely to the Ethernet ports on the LAN adapter or dock and the router/modem. If you are using a USB LAN adapter, ensure it has been installed correctly.
If you are using a USB LAN adapter, connect it to a different USB port on the Nintendo Switch dock.
Situation Not Resolved
If you are still unable to connect, try using an alternate LAN adapter if available.
