Compare Netgear CM600 vs Netgear C7000 AC1900

There is a clear line between these two devices that is separating them. The first one is CM600, which is only a cable modem, and you won’t be able to get the WiFi feature from it. Nonetheless, you can use an additional router using its Ethernet port for that missing feature.

The second one is the C7000, which is a modem router combo and has all the features to be one of the best cable modems for Xfinity. So, this one might seem the best bet for an all-rounder device.

Think again because the CM600 is capable of supporting 400Mbps maximum download speed, which you won’t find on the other one. What you need to do is decide whether you want more speed or something that will serve the purpose of two.

Key Features of the Netgear CM600


As this device specializes in the cable connection only, you will be getting a maximum of 400 Mbps as its download speed. That speed, along with smooth browsing during peak hours, is possible because of its 24 downstream channels and 8 upstream channels. This much speed wouldn’t have been possible unless the DOCSIS 3.0 technology.


The lab test shows excellent performance because of increased channel numbers and improved technology. And, it did not fail us in the field test, which is proven by the real users. We connected a lot of devices and a WiFi router, and we experienced supreme performance.


Like all other cable modems, this one is also supported by most of the cable service providing companies. If you are a subscriber of Xfinity, Cox, Spectrum, or any other major provider, you can use this device. Regarding router compatibility, it allows any WiFi router to connect and work perfectly with it.


The CM600 only allows a coaxial cable for the cable and internet connection and an Ethernet cable with Gigabits per second speed. You can connect a router of your choice to this device and enjoy the features of a specialized router.


To understand how easy this device to set up, you need to buy one. The instruction manual is straightforward to understand, and you will be ready to use the internet within minutes. Once you have put your information to the Comcast’s website and register your device, your modem will be reset automatically through the cable connection.

How Worthy is Netgear CM600 Compared to its Features and Performance?

At first, we thought the price is almost similar to some other combos from Netgear. So, this one is a bit overpriced, considering this is only a modem. Then, we tested and got the performance of a high-end router.
