Know before you buy
The CM2500 is officially certified for use with major U.S. cable providers, including Xfinity, Spectrum, and Cox. We recommend checking your specific provider's 'approved modems' list on their website to ensure compatibility with your current service plan.
This technology allows for significantly faster upload speeds and increased network capacity compared to older standards. It is specifically designed to handle the high bandwidth demands of modern activities like video conferencing, online gaming, and large file uploads.
To reach multi-gigabit speeds, you must connect both 1 Gig Ethernet ports to a router that supports link aggregation. If your router does not support link aggregation, you will be limited to the speed of a single 1 Gig port.
No, the CM2500 is a standalone cable modem and does not provide Wi-Fi. You will need to connect it to a separate Wi-Fi router or a mesh system, such as a NETGEAR Orbi, to create a wireless network for your home.
Active Queue Management reduces network congestion by prioritizing data packets, which helps lower latency and jitter. This results in a more responsive connection, minimizing the lag often experienced during fast-paced online gaming.
