## Bottom Line

The NETGEAR Nighthawk CM3000 is an excellent choice if you’re aiming to unlock ultra-fast DOCSIS 3.1 speeds up to 2.5Gbps and want a modem built to handle today’s beefiest cable internet plans. It shines with stability and performance across all major providers, making it ideal for power users craving lag-free gaming and seamless streaming. However, if you rely heavily on wired or wireless security camera systems, compatibility issues could be a dealbreaker, and pairing it with your own Wi-Fi router is a must since it doesn’t have built-in wireless.

If built-in Wi-Fi or better security camera compatibility is top priority for you, you might want to explore other modem-router combos or look for feedback on alternative setups that specifically note these features. Otherwise, for sheer raw speed and future-proofing, this one’s a savvy pick.
