Nighthawk X4S AC2200 Tri-band Wi-Fi Range Extender provides speeds up to 2.2 Gbps while high-power internal antennas extend Wi-Fi range in hard-to-reach areas of your home. One Wi-Fi Name with any router uses the same Wi-Fi name as your existing Wi-Fi and provides seamless connectivity across router and extender as you roam throughout the house. Unlike other dual-band extenders, the Dedicated Wi-Fi Link helps establish an exclusive connection to the router that avoids automatic bandwidth reduction of extended Wi-Fi signals. Smart Roaming intelligently connects your mobile devices to the best available Wi-Fi for superior streaming as you move around your house.
