Netgear CM600 DOCSIS 3 Cable Modem

Netgear released new DOCSIS 3.0 Cable modem – Netgear CM600 DOCSIS 3.0 cable modem provides internet speeds up to 960Mbps with 24/8 Channel bonding.


When Netgear had not produce various models of cable modem but a couple of models, the cable modem market was controlled by major player from Motorola (which is now under Arris umbrella) with its Surfboard series products. Take one as an example Surfboard SB6120 that dominated the market and so did Surfboard SB6140 series, almost no one could grap the domination of Surfboard series. But now, Netgear with its various models of cable modem gradually shares the market of cable modems.

A couple of months or so when Netgear released CM500 DOCSIS 3.0 cable modem to compete with Arris Surfboard SB6183, a new faster model is introduced – the Netgear CM600.  See also comparison between CM500 and Surfboard SB6183 which feature 16/8 channel bonding.

What this CM600 does

Netgear CM600 is a high speed DOCSIS 3.0 cable modem delivering downstream speeds of up to 960Mbps (24x channel bonding) and upstream speeds of up to 300Mbps (8x channel bonding).

Speeds up to 960Mbps is marvelous. Is there any existing cable provider able to deliver speeds of up to 960Mbps to the customer’s premises? I guess no, but the technology evolves so quickly and there is nothing wrong if you have a product that has been prepared with the development of technology in the future.

Do you still remember that many years ago your laptop still used dial-up connection at the speed of only 56kbps through telephone lines. And now almost everyone has forgotten that dial-up connection because existing technology including 3G/4G and broadband internet connections delivering speeds of up to 500Mbps and even faster. So that’s why many vendors offer cable modems with faster speeds than ever before.


Netgear CM600 is one of DOCSIS 3.0 cable modems available in the market today, many models from various vendors come with various channel bonding features. Here are some models that can be compared with CM600 cable modem regarding the number of channel bonding features.
