Review your network's password information, and check the security setting within your console's Internet settings. Ensure you are entering the password exactly as it appears, and include any unique capitalization or symbols that may be used.
Power cycle your home network.Restarting your network devices may resolve this issue if it is related to the devices being unresponsive.
Move the Nintendo Switch console closer to the wireless router.If possible, place the Nintendo Switch within 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.
Move any metal objects or electronic devices away from your Nintendo Switch console and wireless router.

Create a new wireless Internet connection file.When creating a new Internet connection, ensure your console is attempting to connect to the correct wireless network and that it is receiving a strong wireless signal.
Check the MAC filtering settings of the wireless router.If the wireless router you are attempting to connect to has enabled MAC filtering, this will block your console from connecting. You can resolve this by entering the Nintendo Switch console's MAC address into the router settings, or disabling this setting.
Disable the password requirement on the router and test without this.If you are able to connect online without a password enabled on the wireless router, it could indicate an error related to this setting on the router. If this is the case, try changing the wireless password or wireless password type (e.g. change this setting from WPA-AES to WPA2-AES) and see if this resolves the error.
If you change the wireless password setting on your router, you will need to update this setting on any wireless devices that connect to your router (laptops, smart devices, etc.).
