Yes, you can often use your existing router with fiber optic internet, but there are crucial considerations. Understanding compatibility, potential limitations, and when an upgrade is necessary will ensure you get the most out of your high-speed connection. This guide will break down everything you. Fiber internet requires a device called an Optical Network Terminal (ONT) to convert the light signals from the fiber optic cable into electrical signals that your router can understand. Many major ISPs, such as Verizon and Xfinity, offer fiber connections directly to your door, known as FttP or Fiber. Routers that feature 10-gigabit Ethernet (10GbE) and other multi-gig ports help remove the final speed limit between your modem and your connected devices. A NETGEAR WiFi 7 router pulls service from the modem through a 10GbE WAN port, then pushes that full bandwidth back out over matching LAN ports. Yeah just because a router has a 10Gbps port, doesn't mean it can route at 10Gbps.
