Please make sure your Airport Express is not set to bridge mode as DNS changes will not work. Instead, set DNS on your main router or remove bridge mode.
- Open Airport Utility found in Applications > Utilities.
- Select the Airport Express from the menu and click edit.
- Select the Internet Tab.
- In DNS servers, input 212.32.240.145 and 104.200.137.81
- Click update and wait for the Airport Express to restart.
- Restart the devices connected to the Airport Express that you want to use with our DNS.
Important
The first step of troubleshooting should always be to restart the device(s) and router. Then check your setup status in your SmartDNS dashboard.
