Fast, easy, reliable

My internet went down, so I found out that my equipment was alittle outdated (old)! So the first place I looked was for netgear. It's always been reliable and easy to use. Plus that's what I've always used...there's nothing better!

Works Great

Very easy install/activation. Very little configuration. Works with all my previous devices/connections. The Nighthawk app is easy to use and works with my older router and the newer modem.

Perfect For New Internet Speed of 800 mbps

I had to upgrade my old Netgear modem to allow for my new internet speed of 800 mbps. The CM1200 was a very good value option. It is perfect for people who have a separate router and satellite system.

Game Changer!

I've been a long time user of multiple networking devices by Netgear, most recently the Nighthawk AC1900 Modem/Router Combo with Wi Fi 5 capability. Although, I now have dedicated devices for Wi Fi 6, the CM1200 Modem has been a game changer with my Xfinity internet service.

Not quite docsis 3.1...

Works very well most of the time. However I've been having periodic connection issues. The Xfinity service person verified internet and said this modem is not fully up to docsis 3.1 standard, that it is more a 'transition' modem between 3.0 and 3.1. I've had two separate service calls and they've blamed the modem each time. I've had it less than a year and will likely need to replace with a true 3.1 modem.

Performed better than I expected

I finally cut the cord to cable. My xfinity modem/router had weak coverage and didn't want to pay to rent crap equipment. Handles streaming TV's and other devices throughout my home AND yard !

Nighthawk Modem 3.1

Just purchased new modem from Amazon. The setup required us to call our internet provider to set it up (unlike what the directions say about doing it with an Ethernet cord and laptop), but it was fairly quick and easy. It has run smooth ever since.

Terrible modem

Only 1 Ethernet works on the modem, the rest are useless. I called tech support and after 30 min hold they said the same thing. I need to buy a router even with the other ports being available to use.

Great Cable Modem!

Happy to own 3 of these very fast CM1200 cable modems. We don't like paying the cable internet supplier forever for their equipment. These are very reliable and easy to setup units.

Won't accept dialup

The product was highly recommended and I will keep it for future use but now I can not use it because My area has only dial up internet access with local telco your unit doesn't accept that type of feed. A coax input I did not realize that till I tried to install it. I am hoping for better service so I can use your product

NIGHTMARE

Bought this 2 years and Cox couldn't get it to work. Tried again Jan 2025 and once again Cox couldn't get it to work. It's my honest opinion that Cox is the problem. Two good installers and concerned service agents couldn't over come Cox's ignorant world of confusion when it comes to electronic service. I'm back to my CM500 and two full days of trial and error to get my service back working. Do I win the money now?

CM1200

By ermed5

Great router, speeds are good. But this was confusing, as it has 4 separate Gb ports on the back. Thinking 4 separate wired devices could be directly attached, I purchased this unit. I came to realize that these are WAN/LAN ports, and cannot be used for direct connections to devices. A switch must be used after the router, as IP configurations are not available from these WAN/LAN Gb ports. Silly me. $200 mistake.

Nighthawk modem works great ever since I got rid of my internet provider modem!

Take your online experience to unprecedented heights with the NETGEAR Nighthawk CM1200 Multi-Gig Speed Cable Modem, a powerhouse of connectivity designed for the most demanding internet users. Whether you're a hardcore gamer, a virtual reality enthusiast, or a streaming aficionado craving 4K Ultra HD clarity, the CM1200 is engineered to exceed your expectations and elevate your digital life.

Harness the full potential of your internet service with the CM1200's support for link aggregation, which enables true Multi-Gig internet speeds that can transform your online activities. This advanced feature allows the modem to combine two Gigabit Ethernet ports to deliver up to 2Gbps download speeds, provided your internet plan supports such performance. This is particularly beneficial for activities that demand high bandwidth, such as streaming high-definition content, engaging in competitive online gaming, or uploading critical data to the cloud, like security camera feeds.

The Nighthawk CM1200 stands out with its capacity to support up to four public IP addresses (WAN IP) with a Comcast Business account, making it an ideal choice for users who require multiple servers to operate simultaneously. This capability facilitates the running of various home networks, ensuring that your personal and professional digital realms can coexist without compromise.

Compatibility is at the core of the CM1200, offering seamless integration with existing DOCSIS standards. It's ready to go right out of the box with major internet cable services such as XFINITY from Comcast, Spectrum, and Cox, and allows for effortless self-activation, bypassing the need for a service call. The modem's backward compatibility ensures that you can continue to enjoy your current internet service while being primed for the fastest speeds as soon as your provider upgrades to DOCSIS 3.1.

DOCSIS 3.1 technology is a game-changer, offering a significant leap in both download and upload speeds - up to 10 Gbps for downloads and 1 Gbps for uploads. This cutting-edge technology not only reduces latency for a smoother gaming experience but also enhances the performance of high-speed applications like virtual and augmented reality.

The CM1200 is not just about speed; it's also about convenience and security. With support for IPv6, the latest internet standard, you can rest assured that your connections are efficient and future-proof. The modem's sleek design is easy to integrate into your home setup, and despite the availability of four Ethernet ports, it remains user-friendly and straightforward to configure.
