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. Instead, you simply plug a wireless router into the ONT provided by your ISP, set it up, and start using the internet. Regardless of who your internet provider. Instead of using your old router, a high-performance Wi-Fi router designed for fiber optic internet will ensure you seamless streaming, online gaming, and remote work all over your space.
