Setting up your Tenda AX5400 Mesh WiFi 6 System is designed to be quick and easy, typically taking only minutes. You can use either the Web GUI or the Tenda Wi-Fi APP for installation.
Initial Setup Steps:
- Connect the Main Unit: Select one MX15 Pro unit to be your main router. Connect the network cable from your wireless modem to the WAN port of this unit.
- Power On: Plug in the power adapter to the main unit and connect it to a power outlet. Wait for the unit to boot up (the LED indicator will turn solid green).
- Access Setup Interface:
- Using Tenda Wi-Fi APP: Download the Tenda Wi-Fi APP from your smartphone's app store. Connect your smartphone to the default Wi-Fi network of the main unit (SSID and password are on the label at the bottom of the unit). Follow the in-app instructions to complete the setup, including setting your new Wi-Fi name and password.
- Using Web GUI: Open a web browser on a computer connected to the main unit's default Wi-Fi network or via an Ethernet cable. Enter the default IP address (usually

- Add Other Nodes: Once the main unit is configured and online, power on the remaining MX15 Pro units. They will automatically detect and connect to the main unit, forming a seamless mesh network. This process typically takes about 2 minutes per node. Ensure the node LED indicators turn solid green for successful networking.
