- Connect the power adapter to the secondary unit and plug it into a power outlet.
- Wait for the secondary node's indicator light to blink yellow.
- Open the MU-LINK app on your smartphone. The app home page should show the number of devices that can be added. Follow the app's instructions to add the new node to your existing network.
- Once successfully connected, the LED on the secondary unit will turn solid green. If it does not, reset the secondary node and try the process again.
Method 2: One-Button Networking via Mesh Button (For adding a single node)
- On the connected primary mesh node, press the 'Mesh' button. The green light will blink rapidly.
- On the powered-up secondary mesh node, press the 'Mesh' button. The yellow light will blink rapidly.
- The two devices will automatically enter the networking process. Wait for the LED on the secondary unit to turn solid green, indicating a successful connection. If it does not, reset the secondary node and try the process again.

6. Troubleshooting
If you encounter issues with your DBIT AX1800 Mesh Wi-Fi System, consider the following troubleshooting steps:
- No Internet Connection:
- Check if your modem is working correctly.
- Ensure the Ethernet cable is securely connected between the primary mesh unit and the modem.
- Restart both your modem and the primary mesh unit.
- Verify your ISP settings in the MU-LINK app or web GUI.
- Weak Wi-Fi Signal/Dead Zones:
- Relocate secondary mesh units closer to the primary unit or to a more central location.
- Ensure there are no major obstructions (thick walls, large metal objects) between mesh units.
- Add additional mesh nodes if your coverage area is larger than 4,000 sq. ft.
- Devices Disconnecting Frequently:
- Ensure your mesh units are running the latest firmware.
- Check for interference from other electronic devices.
- Reset the problematic device's network settings and reconnect to the mesh Wi-Fi.
- Cannot Access MU-LINK App/Web GUI:
- Ensure your device is connected to the mesh Wi-Fi network.
- Verify the IP address for the web GUI (usually printed on the unit's label or found in the Quick Installation Guide).
- Try restarting the primary mesh unit.
- Resetting the System: If all else fails, you can perform a factory reset. Locate the reset button (often a small pinhole) on the back or bottom of the mesh unit. Press and hold it for about 10 seconds until the indicator lights change, then release. Note: This will erase all your custom settings, and you will need to set up the system again.
