Overview

Our take on the NETGEAR CM1000

If you're paying your cable company for high-speed internet, you owe it to yourself to run it through a modem that can handle the job. Rental modems put a monthly charge on your bill, and they're often a couple of generations out of date. The NETGEAR CM1000 can handle speeds up to 1 Gbps, plenty fast enough to keep you streaming 4K Ultra HD video with no hiccups.

2 questions already asked

Yes you can definitely use a single device connection or you can buy a splitter used that way and later on you can buy a wireless router. I'm using the orbi wireless router with this modem and works flawlessly [ Edgar  Jun 07, 2018 ]
I see no reason why this setup wouldn't work. [ Michael  Jun 06, 2018 ]
Yes, it has one LAN line output, so you can plug in just one device if you wanted to. [ Jin  Jun 06, 2018 ]
Netgear confirms compatibility with most major US cable ISPs ("Comcast XFINITY, Time Warner Cable, Cox, Charter, Cablevision & more") but does not specifically list "Optimum" so, you'll want top check with your ISP directly to confirm. [ Ryan  Jan 20, 2018 ]  Staff
