Our take on the Netgear Nighthawk CM2050V

The Nighthawk CM2050V is a DOCSIS 3.1 cable modem built for Xfinity service, with 32 downstream and 8 upstream channels and a 2.5 Gbps Ethernet port. It adds two telephone ports for voice service, so it replaces both a modem and an Xfinity voice box. It has no built-in Wi-Fi, so you pair it with a separate router. Compared with basic 1 Gbps modems, it is aimed at multi-gig Xfinity plans and households that still keep a landline.
