5.0 out of 5 stars Consistent & Fast Internet Connection
Reviewed in the United States on January 17, 2023
I upgraded to a Motorola MB8611 modem and a new ASUS router in 2021 to fully utilize the speed in my Xfinity plan. I had occasional, brief disconnects from the internet early on. However, these disconnects continued to increase in number over the year until recently it was dropping off several times a day. After checking cables, connection to Comcast, modem resets, etc., I decided to switch out the modem. I had considered the Netgear CM2000 (up to 2.5 gigabits) modem initially but went with the less expensive Motorola since I had used Motorola modems in the past without problems.

The Netgear modem setup was very straightforward as I already had the Xfinity app loaded on my phone from the previous installation. Activation via the Xfinity app took only a couple of minutes and a couple more minutes for the modem to restart. Worked with my router without any issues as soon as I plugged it into that device.

Download speed varies as expected during the course of the day/night, but it usually exceeds the fastest speeds I got from the Motorola. It’s been over a week and, so far, no disconnects! Keeping my fingers crossed…

Added note: I usually decline the Amazon protection plans, but I did add them to the earlier order. Making the claim on the old modem was very simple and quick. I did wait until after the holidays and delivery delays were over to return the old modem, using the prepaid label Asurion had sent me. I was credited with a refund for the full price that I paid for the modem (excluding tax) via an Amazon gift card within just a few hours of dropping the box off at the UPS store.

Update 12/10/2023. It's been about a year since I bought and installed the NETGEAR Nighthawk Multi-Gig Cable Modem (CM2000). Still working flawlessly with no slowdowns or disconnects from the Comcast account.

5.0 out of 5 stars so far so good
Reviewed in the United States on July 3, 2024
significantly better than the provided internet modem. Boosted signal right from the jump. installation was a breeze. I don't have any complaints right now. will update if something comes up. but so far (knock on wood) I've had 0 issues with any NETGEAR tech. I've had the nighthawk router for 3+ years now and never had any issues. so, hoping the same for this modem.

5.0 out of 5 stars Works perfectly--if you know what to do.
Reviewed in the United States on July 9, 2023
This device was set up and working perfectly in 15 minutes--but it is very important to know how to best do it, which I discovered from various online forums. It is designed to work with Xfinity, and is more expensive because it has phone ports, which were important to us. If they are not important to you, buy a cheaper model. Now for the set-up. The most important point in setting it up is to NOT deal with any verbal phone tech support, and it will become clear why. Xfinity's own website describes how to use the mobile phone app for setup--use it. Once you have downloaded the phone app and signed in to it, it allows Xfinity to identify you and know where your service is immediately. In the app, go to Account, Add new device, Your own--and follow the directions. The only input required of you is for the CM MAC number which is on the bottom of the unit. They do not need or want the MTA MAC number--forget about it. It took 8 minutes for their system to identify the device, and about another 6-7 minutes to set it up. That was all, and everything, phone line included, worked perfectly with my correct phone number. Given my previous interactions with Xfinity, I was amazed at how seamlessly this worked. They have gotten their act together--almost. Here's the hooker. I went on the the Xfinity website, and it had immediately identified that I now had my own modem. But I also wanted to call Xfinity to confirm that the old modem/router would be taken off my bill once I returned it--big mistake. Their automated phone tree started off by saying that it had detected a problem with my modem and wanted permission to reset it!!! I shouted no, no ,no and hung up. What I suspect is going on is that the Xfinity answering system and probably any employee you would talk to is operating off a legacy system which does not update immediately, like your account website and whatever infrastructure uses the mobile phone app to set up new equipment. The bottom line is to use the new mobile phone app for any setup and NOT, under any circumstances call for any tech support, verbal or automated, because they are not immediately in touch with the new setup infrastructure. I hope his helps any subsequent customers. With the new setup system, the device worked immediately and flawlessly.

1.0 out of 5 stars Does not presently work well with XFINITY - do not buy
Reviewed in the United States on March 6, 2024
I am in the process of troubleshooting this Modem with XFINITY & Netgear and if successful I will update this review to be more positive.
Presently however, this Modem will only give you 500M (max.) on the Xfinity network, typically less than that.
Apparently there is an issue that is still being worked, as shown below:

>>>>>>>message from XFINITY/COMCAST>>>>>>>>>>>>>>>>
We've identified an issue with your NETGEAR internet modem.

We've noticed intermittent connectivity issues with your internet service and have identified the cause to be a defect with your NETGEAR CM2050V internet modem. NETGEAR is working on a software update that should fix the problem. Because the update may not be available for several months, we have taken steps in the interim to stabilize your connection and provide you with the best possible experience. These proactive measures should resolve your intermittent connectivity issues and provide you with fast speeds, but your modem may not achieve the full upstream speeds included in your Xfinity Internet package until the NETGEAR CM2050V software update is deployed.

No action is required at this time. However, if you want to ensure you're getting the full speeds included in your internet package, you may want to consider these options:

•Lease our Xfinity Gateway, which is a combined modem and WiFi router designed to deliver enhanced coverage and the benefits of our next-generation Xfinity 10G Network. •Purchase a new modem from our recommended device list
