To get the most out of your fiber connection, consider a dual-band or tri-band router. Dual-band routers can broadcast signals on two frequencies: 2. 4 GHz, which provides wider coverage but slower speeds, and 5 GHz, which offers faster speeds but shorter range. These routers allow you to connect multiple internet sources—like cable (Comcast, Cox), fiber, cellular (Verizon, T-Mobile, AT&T), or low earth orbit (LEO) satellite services like Starlink—into a single networking device. But simply plugging in two or three internet connections doesn't. Fiber internet delivers the fastest speeds — up to 5Gbps. However, you need a router capable of supporting multi-gig speeds to get fiber internet connectivity. Here's how to choose the best router for fiber.
