Customer Ratings & Reviews

Plugged it in, powered on and in less than 10 minutes I was on Xfinity service. No issues in 3 weeks. I have signed up for 150 Mbps service but Speedtest has reported up to 179 Mbps. Soooo much faster than my 12 Mbps DSL service.

I just updated my modem bc I was haveing some lag issues and thought it was my internet company first, but then I noticed that some games ran fine while others were lagish. I bought this one to try out and haven’t had issues since.

Looks rather plain, but it has what you need. Gigabit speed and DOCSIS 3.1.

Netgear has produced a great cable modem that fully utilizes all the enhanced resources in DOCSIS 3.1 I pay for Comcast 300 mbps and on speedtest regularly receive 340 to 370 with this modem. Added bonus no rental fees from Comcast.

I purchased this modem when I switched from Comcast Xfinity to Century Link. I needed a modem that was compatible with the internet provider. It worked well but after doing a more in depth research I leaned that this modem is more than I needed at the time and in the near future. The reason I returned this modem was because Century Link (or some other internet providers) are not all nationwide or provide service in all major or smaller cities. Since I am moving in 2020 to a dogfeeent city having this modem may not be needed it may not be compatible with other internet providers. Also, the DOCSIS 3.1 is a very new technology and by the time this is nationwide standard this modem may be old or obsolete therefore I chose to return it and rent the one from my provider at this time until another unit comes out at a lesser price. For the most, it worked very well and I have no complains of this modem. The “one star” is for the price for the new technology and it’s price tag. I still recommended if you are to stay put in your current location but for someone like me who relocated every 4 years (military) it makes little sense.

Works great! Got it because we needed one with a router built in.

When my old modem died I bought this modem and am very pleased except for one thing. After installing, my internet connection slowed to a crawl. A little troubleshooting found the problem. The only DOCSIS 3.1 modem available came with a Cat 5 cable to connect to my router. ?!?!? Does Netgear know where I can get a Corvette speed limited to 45 mph to go with it? Luckily I had a Cat 6 cable that I was using with the old modem that fixed the problem. Very disappointed on that one point. You can't fit 1gb through a 100mb line.

The nighthawk 3.1 works so much better than the 3.0 i had. Faster down loadsand better streaming. No more wating for the page to loan

This modem is simply amazing. Quiet, fast, and has a slim design that takes up very little space. The only thing odd is after all the packaging and advertising that the modem is compatible with Spectrum Internet, their system cannot find or recognize the modem.

My old cable modem is slow and need a faster modem to take advantage of the new Spectrum download speed for streaming TV. This cable modem work with Spectrum and easy to setup. Couldn't be happier.

Easy setup very fast internet speed on Xfinity. Very happy with this modem.

Works amazingly well for all our internet needs. Speed has been really good and consistent throughout the apartment. Setup was a breeze as well. Highly recommend for your current needs and to be future ready with 3.1.

Had issues with a DOCSIS 3.0 modem and replaced it with this one - since then no issues and have been getting the advertised speed from my ISP. Haven't had to restart this at all since installing it, fantastic modem.

I replaced my not-so-old Netgear DOCSIS 3.0 with this model and it just works. Because it is also a Netgear product and uses the same power plug, I was able to simply replace it and have it up and running in a few minutes. The improved DOCSIS 3.1 hardware definitely works better with my cable system and my connection is more stable and the 1Gbps speed ensures I am getting the most from my subscription.

I purchased this modem so I can future proof my home network. I am so p,eased with this unit. This is the first unit that has never had any lag and I get fadpstwr than advertised internet speeds. This unit is very reliable.

Works great, easy setup and fast shipping. Reliable.

Bought this because I upgraded my internet oeed to 1,000mbps . It is the only one Best Buy carries that can handle that speed. I got an Amazon prime match , so I got it for only $145. Great deal and user friendly. 5 stars

this is a must if you have giga speed internet. it works at advertise. no more connection problem. and it will be best if you pair this with wifi6 router.

We use this in our vacation home paired with the Orbi AC 2200. We couldn't be more satisfied. It's compatible with Xfinity and setup was a breeze. Did it all online. I only wish that it was compatible with Optimum (Cablevision).

It was pass time to replace my modem. I was so happy to find arris would be my router and modem. It was so easy to install. The app online was so helpful with the installation. It is running so much faster. It’s a great product.
