Should the router be connected to the fiber optic LAN port or the LAN port

Your router should be connected to the WAN port, not a LAN port, using an Ethernet cable from the Optical Network Terminal (ONT) that converts the fiber signal. Understanding the PortsWAN Port: This port on your router connects to the internet via your ISP. It receives the external network signal and allows your router to distribute it to your local devices.

LA

N Port: These ports connect local devices like computers, printers, or switches within your home or office network. Traffic between LAN devices stays internal unless it needs to access the internet.

Fiber Optic Connection Setup

Fiber to ONT: Fiber optic cables from your ISP terminate at an Optical Network Terminal (ONT), which converts the light-based fiber signal into an electrical Ethernet signal.

ON

T to Router: Use a high-quality Ethernet cable (Cat6a or higher) to connect the ONT's Ethernet/LAN port to your router's WAN port. This ensures your router can access the internet. Router Configuration: Power on the router and configure it using the admin panel, entering any ISP credentials if required.

Why Not Connect to a LAN Port? Connecting the router to a LAN port instead of the WAN port will not provide internet access because LAN ports are designed for internal network traffic only. The router will treat the connection as a local network link, and devices will not be able to reach the ISP.

Summary

Always connect the router's WAN port to the ONT's Ethernet/LAN port.

LA

N ports are for connecting local devices, not for receiving the internet signal.

The ON

T is essential for converting the fiber optic signal to Ethernet, which the router can then distribute to your network. Following this setup ensures your fiber optic internet works correctly and your local network operates efficiently.
