How to set up a wireless router with a fixed IP address and fiber optic connection

You can set up a wireless router with a fixed IP over fiber by connecting the ONT to your router via Ethernet and configuring the router's WAN interface for a static IP.

Step 1: Connect Fiber Optic Cable to the ONT

1. Locate the fiber optic wall outlet where your ISP's fiber line enters your home.
2. Connect the fiber optic cable to the ONT (Optical Network Terminal) provided by your ISP. Ensure the connectors (SC/APC or SC/UPC) are properly seated to avoid signal loss .
3. Power on the ONT and wait for the status lights to stabilize (usually 2–5 minutes).

Step 2: Connect the ONT to Your Router

1. Use a high-quality Ethernet cable (Cat6a or higher) to connect the ONT's Ethernet/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 3: Access Router Settings

1. On a computer connected to the router (via Wi-Fi or Ethernet), open a web browser and enter the router's IP address (commonly 192.168.0.1 or 192.168.1.1).
2. Log in with the admin credentials provided by your router manufacturer.

Step 4: Assign a Fixed IP Address

1. Navigate to the WAN or Internet settings section of your router.
2. Select Static IP or Manual IP as the connection type.
3. Enter the IP address, subnet mask, gateway, and DNS servers provided by your ISP .
4. Save the settings and reboot the router if necessary.

Step 5: Optional – Reserve IP for Specific Devices

1. Go to the DHCP server or LAN settings in your router interface.
2. Use Address Reservation to assign a fixed IP to a device by entering its MAC address and the desired IP .
3. This ensures that the device always receives the same IP even if DHCP is enabled for other devices.

Step 6: Verify the Connection

1. Check that your router is online and that the fixed IP is active.
2. Test connectivity by pinging the gateway or accessing the internet.
3. Ensure no IP conflicts exist with other devices on the network.

Tips for Optimal Fiber Setup

• Place the ONT close to the fiber entry point to minimize signal degradation .
• Avoid sharp bends in the fiber cable and keep connectors clean.
• Enable Quality of Service (QoS) if you use VoIP or video conferencing to prioritize traffic .
• For multiple static IPs, configure static routes on additional routers or firewalls to point to the gateway IP . By following these steps, your wireless router will be properly connected to fiber optic internet and configured with a fixed IP, ensuring stable connectivity and predictable network addressing.
