Topic: Nintendo Switch Error Codes | Status: Updated

What is this error?

Error 2110-3400 on the Nintendo Switch typically indicates a network connection issue, often linked to problems with the device's ability to connect to the internet. This may be due to various factors including router settings, a poor signal, or issues with the Nintendo servers.

How to Fix It

  1. Check Your Internet Connection: Ensure that your router is powered on and functioning correctly. You can test this by connecting another device to the Wi-Fi.
  2. Restart Your Nintendo Switch: Hold down the power button until the power menu appears, select "Power Options," then choose "Restart." This can often resolve temporary connectivity issues.
  3. Move Closer to the Router: If you’re using Wi-Fi, try to be in closer proximity to the router. A weak signal can lead to connectivity errors.
  4. Check Router Settings: Access your router settings and ensure that any firewall or parental controls are not blocking the Nintendo Switch. Ensure that the router firmware is up to date.
  5. Forget and Reconnect to Network: Go to the Nintendo Switch settings, navigate to "Internet," then "Internet Settings." Select your network, choose "Forget," and reconnect by entering your Wi-Fi password.
  6. Use a Wired Connection: If possible, connect your Nintendo Switch to the router using a wired LAN adapter. This can often provide a more stable connection.
  7. Change DNS Settings: In the Internet settings, select your network, choose "Change Settings," then "DNS Settings." Select "Manual" and enter an alternative DNS such as Google's Public DNS: 8.8.8.8 and 8.8.4.4.
  8. Check Nintendo Server Status: Visit the official Nintendo support website to verify if there are any ongoing server outages that could be causing the error.
  9. Contact Nintendo Support: If none of the above steps resolve the issue, reach out to Nintendo Support for further assistance.
