Setting up a fiber optic cable on a Xiaomi Router 4

To connect your Xiaomi Router 4 to a fiber optic internet connection, you need an ONT (fiber modem), an Ethernet cable, and proper router configuration.

Step 1: Gather Required Equipment

• Optical Network Terminal (ONT): This device converts the fiber optic signal into an Ethernet signal your router can use. It is usually provided by your ISP .
• Xiaomi Router 4: Ensure it has a free WAN port for connecting to the ONT.
• Ethernet Cable: Preferably Cat6 or higher to maintain high-speed fiber performance .
• Fiber Optic Cable: Supplied by your ISP, typically with SC/APC or SC/UPC connectors .
• Power Adapters: For both the ONT and the router.

Step 2: Connect the Fiber Optic Cable

1. Locate the fiber optic wall outlet where your ISP's fiber line enters your home.
2. Connect the fiber optic cable from the wall outlet to the ONT's designated fiber port. Handle the cable carefully to avoid bending or damaging it .
3. Power on the ONT and wait for the status lights to stabilize (usually 2–5 minutes) .

Step 3: Connect the Router to the ONT

1. Use an Ethernet cable to connect the LAN/Ethernet port on the ONT to the WAN port on your Xiaomi Router 4 .
2. Power on the Xiaomi Router 4 and wait for the indicator lights to confirm a successful connection.

Step 4: Configure Router Settings

1. Open a web browser and enter the router's IP address (commonly 192.168.31.1 for Xiaomi routers) to access the admin panel .
2. If your ISP requires PPPoE credentials, enter the username and password provided by your ISP in the WAN/Internet settings .
3. Some ISPs may use automatic configuration (Easy Setup), in which case the router will detect the connection without manual credentials .
4. Save the settings and restart the router if necessary.

Step 5: Test the Connection

• Connect a device to the router via Wi-Fi or Ethernet and check for internet access.
• If the connection fails, verify the Ethernet cable is securely connected, the ONT is powered on, and the router settings match your ISP's requirements . By following these steps, your Xiaomi Router 4 should be successfully connected to your fiber optic internet, providing high-speed and stable connectivity throughout your home.
