      I recently upgraded to this NETGEAR Nighthawk modem, and it has been amazing. Setup was extremely easy, and it worked perfectly with my Xfinity service right away. The speeds are lightning fast and very stable — I noticed a huge improvement compared to my old modem. The design is sleek and doesn’t take up much space. Highly recommend this for anyone looking for a high-performance modem that supports the latest speeds!

      Modem is perfectly compatible with Xfinity. Activation took maybe 2 minutes and is able to handle my high network speeds. The modem is slim, sleek and looks great.

      5.0 out of 5 stars I purchased the CM2000 for one reason only (Update included)
      Reviewed in the United States on May 8, 2023
      Style: (Discontinued) 2.5GbpsVerified Purchase
      The ISP (which will remain nameless), that I rented my Internet gateway from did not adhere to sound security protocol. I myself, as a cybersecurity professional with more than 10 years experience, am naturally paranoid about weak passwords. This particular ISP limits the variety of keyboard characters allowed for cable modem management passwords, making them easier to crack! In fact, on a few occasions, my passwords were changed without my consent. From that point forward I decided to buy my own cable modem that would allow me to choose the access passwords without character limitations. Now that it is up and running I am beyond happy. My desired security posture is now a reality, and my internet finally achieves 1gb downloads, better than the ISP's cable modem that was supposed to do the same thing. My network is tight security wise, and this Netgear Nighthawk CM2000 helped me realize that. Finally, I had to overcome one technical issue that I thought was generated by the CM2000. After registering my cable modem with Netgear, called tech support. Best dang support I've dealt with in a long time! From one geek to another, we were able to speak the same tech-ease and I learned more about my new CM2000 and the DOCSIS standard than I knew before the call. Found out that the CM2000 was not the culprit, so I called the ISP to handle it, problem resolved. The one setback for Netgear that I thought was serious enough to mention is that as far as firmware upgrades there seems to be tit-for-tat between Netgear and this particular ISP. Either group seems to point the finger at the other when it comes to whose responsibility it is to push out firmware upgrades. I hope, for customers' sake, that these two outfits work out their differences on this. Heavens forbid that there is a security vulnerability that requires a firmware upgrade! I shiver to think about that outcome. Other than that, I am very happy with my purchase.

      UPDATE (6/2025)
      It's been a few years since I pinned the above review of the CM2000. Now it's time for an upgrade from the CM2000 to the CM3000. This is what I've learned: The CM2000 performed honorably for the most part. However over time the status LED lights began to shut off one after the other. Today the only one that is still operational is the Online LED. I understand that there are others who've experienced the same malfunctioning LED issues as well. Other than that I am pleased with its performance, so much so that I am considering purchasing it's more mature cousin, the CM3000. The one BIG issue I have with this consumer-class cable modem is what seems to be the unwillingness of its manufacturer Netgear & my cable service provider Xfinity/Comcast to agree on WHO WILL PROVIDE THE FIRMWARE UPGRADES! This was the 800lb gorilla that otherwise would make the experience with this product a 9/10! Just as with the CM2000, Netgear advises users to access their cable service provider for the firmware upgrade for the CM3000. With both devices Xfinity does not have documentation on its website which gives instructions on upgrading the Nighthawk CM model firmware: https://www.xfinity.com/search?q=Netgear%20cm2000 . Similarly, Netgear support encourages users to contact their ISP for upgrades: https://kb.netgear.com/000036375/What-is-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router . Either way, if there is a need for a future firmware update anyone purchasing this item will risk ending up with an expensive paper weight if both the manufacturer and the ISP refuse to come together and resolve the issue. For this reason I am exploring other cable modem options, ones where firmware updates are available for ISP-approved devices.

      1.0 out of 5 stars Does not work with xfinity!
      Reviewed in the United States on July 14, 2025
      Style: (NEW) 2.5GbpsVerified Purchase
      Summary: This modem does not work for xfinity customers. Maybe in the future the two companies will resolve the issue, but for now, you should avoid. Get the Arris S34 instead.

      Pros: Super fast, when it works.

      Cons: Internet connectivity degrades and then drops for 15-60min every day. The root cause is a firmware issue that causes this for xfinity customers (search for "netgear CM3000 V6.01.03, xfinity" and you will see the widespread complaints). This has been going on since May and neither Netgear or xfinity are owning up to fixing the issue. I wasted hours with customer support on both sides and neither of them had the knowledge to be able to resolve the issue. This is not worth your time.

      Reviewed in the United States on July 13, 2025
      Style: (NEW) 2.5GbpsVerified Purchase
      Why did you pick this product vs others?:
      Does as advertised! At almost 2 Gbps, I'm able to get the close to the maximum speed from my Xfinity Comcast provider.

      Configuration took less time than I expected! However, there's a small gotcha: do not use the Netgear Configuration app and rather, use the router web interface. It's quicker and less prone to errors.

      Once the modem was configured, all I had to do was activate it with my Xfinity app and I was done!

      WOW!!!! I had updated my cable modem back in early 2020 and decided to do a network upgrade recently due to very low transfer rates. I got this as I wanted to have one that supports multi gig transfers just in case it becomes an option from my provider. It was an easy change to the new one but the thing that impressed me the most is I am now getting. I have never seen these network rates ever before! It has been 2 days of super fast connectivity.

      Replacing an xfinity gateway was straightforward, even easy. The Netgear Nighthawk CM3000 is a real winner. Quick like a bunny. I’m very impressed, especially when paired with the Netgear RBK853 Wi fi 6 mesh router. Better upload speeds by far than I am accustomed to seeing, and ping that runs from <10 to <20 ms in a large 2 story house. Starting with >600 Mbps, the loss of download speed at the most difficult reach remains at 450-550 Mbps. I am very pleased with the performance.
