Configuring a router using China Unicom fiber optic cable

To set up a China Unicom fiber optic internet connection, connect the fiber to the ONT, link it to your router, configure WAN settings, and set up Wi-Fi. Step 1: Connect the Fiber Optic LineLocate the fiber optic wall outlet provided by China Unicom. Connect the fiber optic cable (usually yellow with SC/APC or SC/UPC connectors) to the Optical Network Terminal (ONT).

Power on the ONT and wait 2–5 minutes for the status lights to stabilize. Step 2: Connect the RouterUse an Ethernet cable to connect the ONT's LAN port to your router's WAN port. Plug in the router and turn it on, waiting for the indicator lights to confirm power and connectivity.

Step 3: Access the Router Configuration PanelOpen a web browser and enter the router's IP address. Common defaults are 192. 168.

1. 1 for ZTE routers or 192. 168.

123. 254 for some China Unicom models. Enter the default username and password, usually found on the router label.

For many routers, the default is admin/admin. Step 4: Configure WAN SettingsNavigate to the Network or WAN tab in the router interface. Select your Internet connection type (commonly PPPoE for China Unicom).

Enter the username and password provided by China Unicom. Save the settings and ensure the router shows an active internet connection. Step 5: Set Up Wi-FiGo to the Wireless or Wi-Fi settings tab.

Set your SSID (network name) and Wi-Fi password. Choose a security type, preferably WPA2 or WPA3 for better security. Save the settings and reconnect your devices to the new Wi-Fi network.

Step 6: Additional RecommendationsChange the default router password to enhance security. Update the router firmware to fix bugs and improve performance.

Enable DHC

P to automatically assign IP addresses to connected devices. Configure optional features like QoS, port forwarding, or MAC filtering if needed. Restart the router if you experience connectivity issues and unplug it when not in use for extended periods.

Following these steps will ensure your China Unicom fiber optic internet is properly configured, secure, and optimized for home or office use.
