Customer Ratings & Reviews

The best part about this modem is that it's cheaper, after a year, than paying Comcast to rent theirs. It's future-proofed with DOCSIS 3.1 so if I get 2 or 3 years out of it I'll be happy knowing I wasn't renting from Comcast and putting more money than is necessary into their pockets. Also, it was easy to install and set-up. Works well with my netgear router. Speeds are consistent, but it comes as no surprise that my "gigabit" service from Comcast is not up to par.

Other than the single coax cable in/out-put, the performance is amazing. We coupled this with the Netgear Nighthawk router and it's truly been life-changing. We no longer rent our modem/router combo (that's supposed to be the best of the best) from Cox!! yay! no more wifi drops in my home office; we can play our games and use wifi on our phones in our bedroom now; our PPV UFC fights don't lag or get fuzzy or freeze anymore!!

Great Modem....great speed works well with the router and it replaced us renting from Xfinity. Just as fast if not better than the modem/router combo provided by xfinity.

Wanted to stop renting modem from Comcast.. setup was simple.. just have to call Comcast with mode, serial # and MAC Address ( gather this info from bottom of the unit before you call). They activate it on your account and you’re all set. And this will be future prod to get faster speeds later. I also like the idea of separate Dedicated modem (like this) so I can change and replace my WiFi router whenever newer tech makes sense to upgrade.

I like this modem a lot. It’s compatible with Cox. I get good speeds. I bricked my previous version of this modem because I tried to power cycle it during a Cox outage. You’re not supposed to power cycle during an outage. Lesson learned.

I was tired of paying rental fees on my Comcast modem, so I bought this to replace it (along with a router). The internet speeds I can reach on this are significantly higher than the old router that Comcast provided. Setup was easy, and I was able to do it without having to call for help from my ISP. All in all a good bargain for the results I am getting.

Our goal was to save money, purchase a modem that was compatible with our provider's service platform and had great coverage and speed. The folks at Best Buy recommended this product and I have absolutely no regrets. It was a home run for our needs!

Runs fast and well. Great for it's price. May get a little hot sometimes.

Comcast recommended I get a new modem to accommodate the speed increase to 200 download. Before the modem change I was getting 125 download speed. After I installed the NETGEAR - CM1000 Ultra-High Speed DOCSIS 3.1 Cable Modem - Black, my download speed increased to a consistent 235. The install was very easy and required little assistance from Comcast. Also the modem's software is upgradeable over time to accommodate much higher speeds. It is expensive but it delivers. Highly recommended.

I purchased this DOCSIS 3.1 modem to support an upgrade to gigablast with our ISP. I was already using an Orbi router with 2 satellites to cover our large 3 story home. We now have wifi speeds between 500-850 mbs depending on which room you are in. Our speeds were between 50-150 mbs with the same router and our old DOCSIS 3.0 modem. It was easy to setup and so far we have much higher wifi speed.

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

I bought this to replace a Netgear C7000v2 that had to be reset at least once a day and never got more than 50% of the internet speed available on my service plan. This modem, paired with an OrbiPro, has been rock solid since I installed it 1 month ago. It never needs resetting. It gives me 100%, and often more, of the internet speed on my service plan. Interfaces flawlessly with the OrbiPro wireless router and satellites.

Installed by calling cox communications support. They asked me plug everything in, turn the power on & report what the lights were doing. It took approx 90 seconds for all solid green lights except for the bottom ethernet light which blinks very quickly. Then it was done and I'm back up and running. Ookla Speedtest on cox.com consistently at 180+ on 150 service (previous ARRIS 6183 consistently around 125). 32 channels locked downstream and 4 locked upstream (only 4 available in my area). Firmware V2.01.14.

After getting set up with internet in my home with Xfinity, the techs couldn't get the system working and they left their modem at my home. I was able to get it working, but their modem was not good, so I purchased this one and took theirs back to them. The Netgear modem is excellent and the speeds are great. I have paired it with my Netgear Nighthawk router and they are working terrific together. I highly recommend this modem.

This modem is an absolute powerhouse when it comes to performance. It has dramatically improved my internet and gaming experience. I've seen a remarkable boost in my download and upload speeds.

Works great would recommend high quality would buy again

I have the Comcast/Xfinity Triple Play (Cable TV, Internet and Home Security). I previously had the voice feature but replaced it with the home security because I never used the voice feature and wanted gig speed. This modem is one that allows gig speed. I get well over 900 Mbps on my desktop and over 500-600 Mbps on my iPhone. I also have the Netgear Orbi router to go with this modem. I highly recommend this cable modem. Easy to install too.

This has been a super solid performer. Works perfectly with Spectrum Internet. YMMV. Highly recommend.

So far it's been great. I upgraded from an 8x4 channel and all the additional channels have made a huge difference with our speed and reliability. A bit pricey compared to other modems but the additional channels and the docsis 3.1 support should give you some "future proofing". Plus in all reality it will pay for itself after a while with the money you save on the equipment rental from your ISP.

I bought this modem to replace my existing xfinity router. Set up was a breeze, didn't even have to call xfinity and the instructions are included. The only bad thing for some is that it only has 1 ethernet output, but I am using it with my linksys ea9500 which has many outlets so it wasn't a big deal. The two of these work amazing together and the modem is very small and lightweight. Just make sure you get a router as well if you plan to use WiFi as this is only a modem.
