My Internet provider initially installed both a router and a modem. It was configured only for band steering and broadcasted only 5 ghz. I needed 2.4 ghz for another smart device. The Nighthawk took the place of two devices and broadcasts 5 and 2.4 simultaneously. I needed 2.4 in order to control a home irrigation system. My new device has solved my problem. Also, it seems to be a lot more efficient than the old equipment. I am not seeing the Internet drop off or buffer as with the old modem and router. I am very pleased with the Nighthawk.
