Our take on the NETGEAR CM1100 Nighthawk

The NETGEAR Nighthawk CM1100 is a DOCSIS 3.1 cable modem with two Gigabit Ethernet ports that support link aggregation for plans up to 2Gbps. It is certified for Xfinity (up to 800Mbps), Spectrum (up to 1Gbps), and Cox (up to 1Gbps), and it works on DOCSIS 3.0 networks too. Unlike many rival modems with a single port, its two ports let you combine connections with a compatible router. Owners say it is easy to set up and reliable once running, though one notes that default settings can slow the connection.
