To connect a fiber optic internet service to your router, use an ONT/ONU to convert the optical signal and link it to the router's WAN port via an Ethernet cable.

Step 1: Install the Optical Network Terminal (ONT)

Fiber optic internet requires an ONT (Optical Network Terminal) provided by your ISP. The ONT converts the fiber optic light signal into an electrical signal that your router can use. Connect the fiber optic cable from the wall outlet to the ONT's designated port and power on the device. Wait for the status lights to stabilize, which usually takes a few minutes .

Step 2: Connect the ONT to the Router

Use a standard Ethernet cable to connect the ONT's Ethernet/LAN port to the WAN port on your router. The WAN port is typically labeled and may be colored differently (often blue) to distinguish it from LAN ports . Ensure both the ONT and router are powered on.

Step 3: Configure the Router's WAN Settings

Access your router's admin panel by opening a web browser and entering the router's IP address (commonly 192.168.1.1 or asusrouter.com for ASUS devices). Log in using the credentials provided with your router . Configure the WAN connection type according to your ISP's requirements:

• Dynamic IP (DHCP): The router automatically receives an IP address from the ISP.
• PPPoE: Enter the username and password provided by your ISP.
• Static IP: Enter the IP address, subnet mask, gateway, and DNS servers as provided by your ISP .

Step 4: Test the Connection

Once configured, check the router's status lights to confirm a successful WAN connection. Test the internet by browsing websites or running a speed test. If the connection fails, verify the Ethernet cable connections, WAN settings, and ONT status .

Step 5: Optimize Network Performance

• Place the router in a central location to maximize Wi-Fi coverage.
• Avoid placing it near metal objects or enclosed spaces.
• Consider using a dual-band or tri-band router or a mesh network for larger areas . Following these steps ensures your fiber optic internet is properly connected to your router, allowing reliable internet access for all devices on your network.
