It’s here- the dreaded 2110-3127 error code, after days and days of connecting to your router without issues. Usually associated with the DNS, the error can take a toll on your entertainment times and can be hard to resolve. In this article, we’ll discuss why this error occurs and the steps to eliminate the same.

The Nintendo Switch DNS error occurs when your console is not able to establish an internet connection, whether wired or wireless. Whenever a device connects to a certain network, it carries out some checks that run in the background. These may include checking the DNS, and internet connectivity, etc. If any of these are not fulfilled, your switch device will show an error.

In this case, too, the DNS that you have entered might not be working or the encryption type may not be working with the wireless network you are trying to connect. When you get the error, a message on the switch screen like the one as shown below will be displayed to you.

Reasons stimulating the error

Internet issues among the primary contributors, there are some other reasons which may cause the Nintendo Switch DNS server error to take place.

Incorrect DNS Settings

DNS forms the core of internet access since it resolves the name of websites for your Nintendo Switch to access. If it is not working, you won’t be able to connect to the internet.

Invalid Security Protocol

If you have incorrect security protocols such as WPA2-PSK selected on your device but not implemented on the network, you’ll receive the error.

Incorrect Configuration

Your device keeps track of all the configurations of the network it accesses, and if any of them are outdated, you will receive an error message.

Fixing Nintendo Switch DNS Error

Before starting with the troubleshooting process, make sure you have a working internet connection. Check the network status on other devices such as your smartphone or your computer. If it shows working, we can move directly to the troubleshooting steps specific to your Nintendo Switch device and not the network. Also, make sure you are not using a network of an institution since they have a firewall set up that protects their network from unauthorized connection requests.

Nintendo Customer Support page suggests testing the internet connection every time you make changes to your Nintendo Switch device. If you are using a Nintendo Switch Lite device, try using a USB LAN adapter with the help of a Dual USB PlayStand or some other licensed accessory.

Solution 1: Disconnect all the devices connected to the network.

Disconnect all the devices that are on the network. This rules out the possibilities of interference caused by these devices, thus causing the internet to slow down. Once all the devices are disconnected, restart both the router and the Nintendo device to see if the problem has resolved.

Solution 2: Power Cycle the Nintendo Switch device.

Upon research both online and offline, the best thing that worked for the most number of people was power cycling the device. There may be instances when your device has been configured incorrectly. Switching your Nintendo device off and again making the power connections from scratch is all you need to power cycle the device. Follow the detailed steps:

  • Hold the power button for some time till a dialog box appears on the screen.
  • Select Turn Off from all the options that appear and allow the device to shut down. Wait for about 30 seconds and power on the device again.

After it turns back on, connect to the network to see if the problem is resolved or not.

Solution 3: Modify Server DNS settings.

Domain Name System or DNS is a system that assigns names to all the devices or servers that are on the network. When you type google.com in the address bar, the name gets converted into a digital format called the IP address by the DNS that can be read by the computer. This initiates the communication between the computer and the internet. The DNS system usually assigns IP addresses automatically, but the settings can be changed manually to help resolve the issue.

Here is how you can change the server DNS settings manually:

  • Click on the Network name to which your device is connected and open the Network settings.
  • Change the value from Automatic to Manual where you see DNS Settings. Click on the Primary DNS Server option and enter 1.1.1.1, now click on the secondary DNS Server and change the values to 1.0.0.1. Save the changes that you have made and run the connection again to see if the issue has been resolved.


If the above addresses don’t work, try using 8.8.8.8 in the primary and 8.8.4.4 in the secondary DNS Server fields.

Solution 4: Change Security Settings.

One more thing that you can do to resolve the Nintendo Switch DNS settings error, is manipulating the network security settings. A number of users have reported that changing the Network security protocols from WPA2-PSK to WPA-PSK and then back again to WPA2-PSK helped them resolve the issue well.

Follow the steps to select the network protocol settings:

  • Right-click on the Network Name that you are connected to open the Network Settings.
  • Go to the Security Menu and change the security protocol value from WPA2-PSK to WPA-PSK (AES).
  • Set a new password and save the changes that you have made.
  • After these changes get saved, head back to the Security Menu, and again change the value from WPA-PSK to WPA2-PSK (AES). Save the changes again and exit.

If the value at the start of Step 2 is already set to WPA-PSK, simply skip step 4. Once done with the above process, try connecting back to the wireless network and enter the password that you had set as a security key.

Finally, Check Your Network

Though implementing the solutions above will definitely help you resolve the Nintendo Switch wifi DNS error, if none of them proved to be of help, there may be some issue with your network. Try connecting to the internet using some other network or contact your ISP for further support. Make sure you troubleshoot the issue thoroughly so you are play games without interruption.
