Blocking Updates

You can add custom DNS to your WiFi connection that will block all communication with the Nintendo servers. This will stop any updates and reporting to Nintendo, but it will prevent use of the eShop and online games.

We will be using 90DNS, a community-run custom DNS server. If you prefer, you can run your own DNS server following the instructions on the GitLab repository.



  1. Go to the Settings applet, and then to the Internet tab.
  2. Select the WiFi network you are connected to and click Change Settings.
  3. Change DNS Settings to Manual.
  4. Pick the Server that is the closest to your device out of the below chart and enter its Primary and Secondary DNS into your connection.
  5. Save Settings and test connection.
Location Primary DNS Secondary DNS
Europe (Server located in France)
America (Server located in the USA)

Example for a 90dns connection with the Europe settings: Visual for System Settings serial location
