The dreaded error code 2110-3127 is usually related to DNS. This error can affect your entertainment time and can be hard to fix. In this article, we’ll look at the causes of this error and the steps you need to take to fix it.

The Nintendo Switch DNS error occurs when the console can’t connect to the Internet, whether it’s wired or wireless. Every time the device connects to a particular network, it performs certain checks that run in the background. This may include DNS checks, Internet connection checks, etc. If any of these checks fail, your switching device will generate an error.

Also, in this case, the DNS you entered may not work or the type of encryption may not work with the wireless network you are trying to connect to.

Which causes the Nintendo Switch error code 2110-3127?

Incorrect DNS settings: Domain name systems are practically the heart of all Internet access, as they resolve the names of various websites that your device can access. If it’s not working, you won’t be able to connect to the Internet.

Incorrect security protocol: Several users have observed that you will get an error if you use the wrong security protocols, such as WPA-PSK or WPA2-PSK, which are not implemented on the network but are selected on your device.

Incorrect configurations on your Nintendo Switch: The Nintendo Switch remembers all network access configurations, and if some of them are incorrect or outdated, you may get the error message under discussion.

How to resolve the Nintendo Switch error code 2110-3127?

Check your console’s DNS settings

This error code indicates a possible problem with the DNS being used. If this problem persists after restarting the console, follow these steps to check your console’s DNS settings:

  1. From the HOME Menu on your Nintendo Switch system, select System Preferences.
  2. In System Preferences, go to Internet -> Internet Preferences.
  3. Select your registered network, and then select Change Settings to check your DNS settings.

If the DNS settings are set to “Manual” but are not required for your network, change them to “Automatic”. Verify that you can connect the console to the network after setting the DNS settings to Automatic.

If your DNS settings are set to Automatic, but your console still can’t connect to the Internet, this may indicate that something is wrong with your ISP’s DNS service. If this is the case, try entering an alternate DNS manually.

How to add alternate DNS :

  1. From the console’s main menu, go to System Preferences -> Internet -> Internet Preferences.
  2. Select the registered network, and then select Change Settings.
  3. Select DNS Settings, then Manual.
  4. You can use the public DNS provided by Google. To do this, simply enter as your primary DNS and as your secondary DNS.
  5. Click the Save button on the right to apply the changes.

Usually, the error code disappears when you switch to the appropriate DNS service.

Avoiding Wireless Interference

A poor wireless network environment can also cause connectivity problems on your console. If your console uses a wireless connection, you can follow the steps below to improve your wireless network environment:

  1. To improve your Wi-Fi signal strength, remove your console from the Nintendo Switch dock and place it 3 to 5 meters away from your wireless router.
  2. Move all electronic devices and metal objects away from the console and wireless router, as they can interfere with wireless signals.
  3. If your wireless router supports the 2.4 GHz and 5 GHz frequency bands, try connecting the console to the 5 GHz band.

Reboot your Nintendo Switch and try again

In most cases, the error disappears after rebooting. To reboot your console, follow these steps:

  1. Press and hold the top POWER button (next to the volume – button) for 3 seconds, then select Power Options -> Reboot.
  2. After turning the console back on, try reconnecting to your home network.

Restart your home network

If you haven’t restarted your home network in a while, try turning off and then turning on network devices such as your Wi-Fi modem and router, as faulty network devices can also cause network problems. Restarting the network can restore a normal Internet connection.

  1. Unplug the modem (and the wireless router if it is a separate device) from the network for 60 seconds.
  2. Reconnect the modem and wireless router and wait for the indicators to return to normal.
  3. Try connecting the console to the wireless router.
