Through extensive research, we have identified a list of potential causes for the Nintendo Switch error:
1. Reboot the Nintendo Switch
As a first step, many users who have experienced this error recommend restarting the Nintendo Switch. Doing so clears any temporary files that may be causing the issue. The reboot method is not only quick but can also resolve other bugs present on the console. If the issue persists after rebooting and you’re still unable to connect to the internet, proceed to the next potential fix below.
2. Enter Manual DNS Settings
Another potential cause of this error is an issue with the default DNS server provided by your ISP. Note: A DNS server is a computer server that stores a database of public IP addresses and their associated hostnames, which it uses to translate those names to IP addresses upon request. If the problem is due to a restricted DNS range by your ISP, you can change to DNS server addresses from a different third-party company.
3. Restart The Router
Resetting your router is another method to resolve internet connection errors. Depending on your router model, you can restart it using the On-Off button. If no button is available, unplug the power cord, wait for 10-15 seconds, then plug it back in. Once the router powers on, check if your Nintendo Switch can connect to the internet.
4. Try a Different Wi-Fi Security Mode
The Wi-Fi Security Mode is the method by which your router interprets your Wi-Fi password. Certain security modes may not be supported by your router, which can cause connection issues. For those using a router that is either low-end or has firmware that is more than four years old, switching the Security Mode to an older encryption type might help.
