Customer Ratings & Reviews

I finally purchase a cable modem several months ago and discontinued renting from Comcast so I don't have to pay a monthly rental fee. I was very please with the performance of this cable modem. It has been running very smoothly for all my connected devices. The cable modem was very easy to set up and the instructions was very easy to follow. I couldn't be more happier with this purchase.

It's difficult to tick all of the boxes regarding an item such as this because part of the proof of any claim of excellence is in the longevity of the device. The Quality portion of this rating is based in part, on my experience with Netgear components in general and an assessment of how 'well made' this particular unit appeared to be when I pulled it out of the box, so, check and check. The value proposition for this device comes down to a price comparison for the features offered, viewed through the lens of the quality assessment previously evaluated ; check again. Finally ease of use. Its setup was really quite easy, except, I had to contact the cable ISP to have them do the necessary cache clearing and resetting of the service configuration on their side. [ugh]. I'm not sure how much of the time spent on that process was so that they could attempt to convince me to convince my client to continue renting a modem from them, but we figured that the ROI is about 16 months or so, compared to the rental, with an expected longevity of at least twice that before we'll consider replacing it, even with inevitable technological advances between now and then. So we declined their several offers to rent. Anyway it was handled and I expect the device to live up to my experience with other Netgear devices. We're happy with it.

Great modem for gigabit speeds. Docsis 3.0 will work fine if slower speeds from ISP. Haven’t had any problems with it. Comcast tried to blame this modem for intermittent drops but after swapping out for their gateway, problems persisted. I was sure the modem was fine but it took a lot of persistance. Make sure you ethernet into the back via 192.168.100..1 (with laptop) to access modem admin mode and verify latest firmware or you won’t get gigabit speeds! You must do a full reset and watch for up and downstream lights to flash together to verify firmware is downloading. Unlike routers, the frmware only comes via ISP but the customer service at ISP (Comcast) have no clue how it happens. Contact Netgear directly for sequence if you can’t get it downloaded. Can be frustrating - wish they would allow user to download latest as they do with routers. Enjoy!

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.

This modem replaced one rented from Astound. It is faster and appears more reliable as it stays connected better than the rental. It was so easy and quick to set up.

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!!

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.

The modem works great and it was a good purchase. Thanks to the employee that helped decide.

Excellent. Works great stay connected and great coverage

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.

This router works really well. I only have 500Mbps, but it works great!

So far the unit is working very well, speed on devices is quicker, less interference on televisions with WiFi 7 router. Just be prepared for some issues connecting with cable company.

This modem is great! I have no issues at all. Easy to install.

Netgear does it AGAIN!! Great Modem, fast, no glitches. Perfect for ALL our families internet needs.

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.

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

Have been using this for 3-4 months now, and have had zero issues. Great connection, and the signal from my router has been consistent as well. Set up was easy, just follow the prompts.

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.

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.

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.
