Huawei AX3 Router Fiber Optic Cable

The Huawei AX3 router connects to a fiber optic internet service via its WAN port, using an Ethernet cable from your fiber modem or ONT.

Connecting the Fiber Optic Internet

The Huawei WiFi AX3 does not directly accept a fiber optic cable; instead, it connects to a fiber optic modem or Optical Network Terminal (ONT) provided by your ISP. Use a standard Ethernet cable (Cat5e or higher) to connect the WAN port of the AX3 to the LAN port of your fiber modem/ONT . The WAN port is specifically labeled for internet input and is separate from the LAN ports used for local devices.

1. Power on the router by connecting the included power adapter to the router's power port and pressing the power button .
2. Connect the WAN port of the AX3 to the LAN port of your fiber modem/ONT using an Ethernet cable .
3. Connect devices to the LAN ports or via Wi-Fi. The AX3 supports dual-band Wi-Fi with speeds up to 2976 Mbit/s, ensuring high-speed connectivity for multiple devices .
4. Configure the router by accessing the web interface at 192.168.3.1 or using the Huawei Smart Home app. Follow the on-screen instructions to set up your Wi-Fi network and passwords .
5. Optional WPS connection: Press the H button on the router to connect compatible devices quickly via WPS .
