In a busy connected home, your internet should live up to your expectations. The NETGEAR Nighthawk CM1000 is a DOCSIS 3.1 cable modem delivering Gigabit download speeds, built for households on Gigabit cable plans today and ready for the upgrades ahead. This is a standalone cable modem with no built-in WiFi. Pair with any WiFi router or mesh system for wireless connectivity throughout your home. A single Gigabit Ethernet port connects to your router or computer for fast, stable speeds. Backward compatible with DOCSIS 3.0, so it works on your ISP's current network and any future 3.1 upgrade. DOCSIS 3.1 OFDM and OFDMA improve response times during peak-hour congestion. Works with Xfinity internet plans up to 800Mbps, Spectrum up to 1Gbps, and Cox up to 1Gbps. ISP activation required after setup. Not compatible with Verizon, AT&T, CenturyLink, DirecTV, DISH, or bundled voice plans. Set up in about five minutes: plug in the coax, activate through a web browser or a quick call to your provider, then connect the modem to your router with an Ethernet cable. Xfinity customers can self-activate online without a service call. Automatic firmware updates keep your modem secure.
