The best router for fiber internet is one that matches your plan speed, home size, and how you use your connection. Our top overall pick is the Netgear Nighthawk RS700S, a Wi-Fi 7 router built for multi-gig fiber plans that handles up to 200 devices across 3,500 square feet. Many major ISPs, such as Verizon and Xfinity, offer fiber connections directly to your door, known as FttP or Fiber. However, you need a router capable of supporting multi-gig speeds to get fiber internet connectivity. Fiber changes the router conversation because upload speed can be just as important. Your gigabit fiber plan is being choked by a router that cannot keep up. A good router designed for fiber-optic connections will remove bottlenecks, maintain stable speeds, and provide reliable coverage throughout your home or office. The real bottleneck in your network isn't the cable coming into your home; it's the hardware translating that signal into usable WiFi, especially when multiple.
