Everything just works and when it doesn’t, it’s easy to find support and get it working the way I want it to. After upgrading my cable internet speed, I needed an upgraded cable modem and this worked flawlessly with spectrum. They were able to add it quickly to their network and it gave me above 1 gb/s speeds right away. Paired with my nighthawk RS600 and my house runs with crazy speeds! Even in rooms across the house, WiFi speeds exceed 900 mb/s.
