Our take on the NETGEAR Nighthawk CM2500 Cable Modem

The Nighthawk CM2500 is a DOCSIS 3.1 cable modem built for mid/high-split cable networks. It supports up to 2 Gbps down and 1 Gbps up, with two Gigabit Ethernet ports that can be aggregated for the full 2 Gbps when paired with a capable router. It works with Xfinity, Spectrum and Cox but not Xfinity Voice plans. It suits households on fast cable tiers that want a plain modem and their own router, rather than a combo gateway.

About the NETGEAR Nighthawk CM2500 Cable Modem

The NETGEAR Nighthawk CM2500 is a DOCSIS 3.1 cable modem built for mid/high-split cable speeds. It supports newer, higher-speed cable plans where available and works with major US providers.

It supports downloads up to 2 Gbps using link aggregation with a capable router, and uploads up to 1 Gbps. It has two Gigabit Ethernet ports for multi-device setups. Actual speeds depend on your service plan and network setup.

The CM2500 is a modem only, so it connects to a separate router. It can be paired with NETGEAR WiFi 6E/7 routers or Orbi mesh systems. For multi-gig speeds, use a router that supports link aggregation.
