Do I still need a router if I have fiber optic internet installed

Yes, you still need a router with fiber optic internet to distribute the connection to your devices, even though a traditional modem is not required.Fiber optic internet uses an Optical Network Terminal (ONT) to convert light signals from the fiber line into digital data that your devices can use, eliminating the need for a traditional modem . The ONT acts as the bridge between your ISP and your home or business network, handling the signal conversion and authentication with the service provider .Role of the RouterWhile the ONT provides the internet signal, a router is necessary to distribute that connection to multiple devices via Wi-Fi or Ethernet cables . The router manages network traffic, assigns IP addresses, and provides security features such as firewalls and parental controls . Without a router, only a single device connected directly to the ONT would have internet access.Router CompatibilityAny router with a Gigabit Ethernet WAN port can connect to the ONT .Routers designed for DSL or cable may work, but older models may limit fiber speeds, especially if your plan exceeds 1 Gbps .For optimal performance, consider routers that support Wi-Fi 6 or 6E, dual-band or tri-band frequencies, and Quality of Service (QoS) features to prioritize critical traffic .Optional All-in-One DevicesSome ISPs provide combined ONT-router units, which simplify setup and reduce equipment clutter . These devices integrate the ONT and router functions, but using a separate high-quality router can offer better performance, security, and advanced features.SummaryModem: Not needed; the ONT replaces it.Router: Required to share the internet across devices.Router choice: Any modern router with a Gigabit WAN port works, but high-speed fiber plans benefit from routers that support advanced Wi-Fi standards and gigabit throughput. Using a proper router ensures you can fully leverage the high speeds, low latency, and reliability of fiber optic internet while maintaining network security and performance.
