For the family that streams, games, and works from home, the ARRIS Surfboard mAX W121 is your solution to Wi-Fi dead zones and slow connections. This isn't just a home security camera; it's a tool for keeping your household connected without interruption, whether you're checking in on kids after school or monitoring a pet during work hours.
Our unique perspective focuses on peace of mind for a working parent. The tri-band system creates three express lanes, dedicating one to maintain a 1 Gbps connection between routers. This means your indoor camera or home security camera with two-way audio and Alexa compatible features streams smoothly, without buffering. The mic picks up a child's murmur from the other room clearly, ensuring you never miss a moment.
Set up is simple and secure with the SURFboard Central app, offering parental controls and real-time monitoring. Experience true gigabit speeds up to 6.6 Gbps and coverage up to 5,500 sq ft, eliminating dead zones in basements or attics.
