To set up a router for a 100M fiber optic connection, connect the fiber to an ONT, link the ONT to a compatible router via Ethernet, and configure the router with your ISP credentials and Wi-Fi settings.

Step 1: Gather Necessary Equipment

• Optical Network Terminal (ONT): Converts fiber optic signals into electrical signals for your router, usually provided by your ISP .
• Fiber-ready router: Ensure it supports at least 100 Mbps; gigabit routers are recommended for future-proofing .
• Fiber optic cable: Typically single-mode with SC/APC or SC/UPC connectors .
• Ethernet cable: Cat6 or higher to connect the ONT to the router .

Step 2: Install the ONT

1. Locate the fiber 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 port .
3. Power on the ONT and wait 2–5 minutes for the status lights to stabilize .

Step 3: Connect the Router

1. Use an Ethernet cable to connect the ONT's LAN port to your router's WAN port .
2. Power on the router and wait for the indicator lights to confirm a successful connection .

Step 4: Configure the Router

1. Access the router's admin interface via a web browser (commonly 192.168.0.1 or 192.168.1.1) .
2. Enter your ISP-provided credentials (username, password, or VLAN ID if required) .
3. Update the router firmware to the latest version for security and performance .
4. Set up Wi-Fi: choose a network name (SSID), strong password, and select WPA3 or WPA2 security .
5. Enable Quality of Service (QoS) if you prioritize video calls, gaming, or streaming .

Step 5: Optimize Your Network

• Place the router in a central, open location for optimal Wi-Fi coverage .
• Use wired connections for devices requiring stable, low-latency performance .
• Regularly test your internet speed to ensure you are achieving close to 100 Mbps .
• Keep fiber connectors clean and avoid sharp bends to prevent signal loss .

Step 6: Troubleshooting

• If the internet light is red, check all cable connections and power cycles .
• Contact your ISP if the ONT or router fails to establish a connection .
• Ensure your router supports the required VLAN or PPPoE settings if your ISP uses them . By following these steps, your 100M fiber optic connection should be fully operational, providing fast, reliable internet for all your devices.
