3.3. Adding More Mesh Nodes
You can add additional mesh nodes using two methods:
Method 1: Via MU-LINK App
- Power up the secondary mesh router(s). Wait for the secondary node's LED light to blink yellow.
- The MU-LINK app will automatically detect the new device(s) for mesh networking. Follow the on-screen prompts to complete the networking process sequentially. Do not attempt to network multiple devices simultaneously.
- The LED turning solid green indicates a successful connection. If the LED does not turn solid green, reset the secondary node(s) and try again.
Method 2: One-Button Networking (Mesh Button)
- Press the Mesh button on the already connected primary node. The green light will blink rapidly.
- Within two minutes, press the Mesh button on the powered-up secondary node. The yellow light will blink rapidly.
- Both devices will enter the automatic networking process. The LED turning solid green on both units indicates a successful connection.

6 การแก้ไขปัญหา
- No Internet Connection (LED not solid green):
- ตรวจสอบให้แน่ใจว่าโมเด็มของคุณเปิดอยู่และทำงานได้อย่างถูกต้อง
- Verify that the Ethernet cable is securely connected between the modem and the mesh router's WAN/LAN port.
- Restart both your modem and the primary mesh router.
- ไม่สามารถเชื่อมต่อ Wi-Fi ได้:
- Check if the mesh router is powered on and its LED is solid green.
- Confirm you are selecting the correct SSID and entering the correct password. The default SSID and password are on the product label.
- Note on Default Password: Some units may have a default password of "1-2-3-4-5-6-7-8-9" printed on the label, which should be used instead of "admin" if "admin" does not work.
- ความเร็ว Wi-Fi ช้า หรือการเชื่อมต่อหลุดบ่อย:
- Relocate mesh nodes to optimize coverage, referring to the placement suggestions in Section 3.4.
- Ensure there are no physical obstructions (thick walls, large metal objects) between your devices and the mesh nodes.
- Reduce the number of active devices or bandwidth-intensive activities if experiencing consistent slowdowns.
- Consider using Ethernet backhaul for critical devices or between mesh nodes for improved stability and speed.
- Secondary Node Not Connecting:
- Ensure the secondary node's LED is flashing yellow before attempting to add it.
- If using the app, ensure you are adding nodes sequentially.
- If the LED does not turn solid green after attempting to add, reset the secondary node and try the process again.
