Customer Ratings & Reviews

I had xfinity xb6 and xb8 gateways and where poor performers. I hooked up this netgear cm2050v modem along with my netgear rs700 router and its a great system now. I have the 1gig internet service with home voice and my download speeds are a consent 1180 mbps down and 82mbps up no matter what time of day it is. The modem has the latest firmware upgrade installed in it.

Fast and a bit better looking than most other modems. I have a gigabit service to my home, and using an Eero 6 router I can achieve 800Mbps+ download speeds with this router. There are more than 50 devices on my network and I've never had speed or interruption issues. Really recommend this modem.

xfinity upped my speed to 800. My old modem couldn't handle that speed. This modem is ace's.. Now I get over 800 on two different speed test program. I'm sure to get a few years out of this modem.

My former cable modem/router failed. After consulting with Best Buy, I decided to purchase a separate cable modem and router. The ease of connection was greatly appreciated. The huge benefit is I immediately received a significant increase in my internet speed. I am sold on NETGEAR products and the value received for the money spent. The other intangible is Best Buy consulting. Overall, a great purchase experience.

Was easy to connect. Worked great out of the box. Much faster than my older one.

Easy setup, fast speeds, I would recommend this product.

Great product. I upgraded to this from the CM2000 Cable Model. The CM3000 takes full advantage of the most recent internet cable provider system upgrades. Previously, I was seeing just under 2Gb/s download and 35Mb/s upload. Now, I'm seeing about 2.6Gb/s down and 350Mb/s upload.

I recently upgraded by modem from the Netgear CM1000 to this new model. The setup was very easy (easier than my last unit) and I immediately saw a substantial increase in the download speed from a max of 20 to 200mps and a upload speed of 1ghb! The only downside was the price point. I was previous getting 500mps on the CM1000 at a price point of $150 in 2016. Now to jump to $300 USD seems a bit pricey. I do recommend this product to people like me who need speed at the home for work but defer to others to use a combo unit at $249 or a lower model for a reduced price.

Xfinity finally decided to upgrade the network in our area so we could get faster speeds. The main issue was mostly the upload speed. After the upgrade, I needed a new modem to take advantage of it. I had a CM1000 before and it's been great, so I got this CM3000 to replace it. Upload speed has significantly improved, to the extend Xfinity offers in the plan anyway. Also allows me to prep for other network upgrades to make my stuff multi-gig ready!

So much faster right out the gate. The older model does not support the demand of these extreme speeds. This newer version does the job

I upgraded to the Cm 3000 from the spectrum supplied cable modem and glad I did. I also did upgrade my isp to 1 gig. Matched with the new netgear router my tv views are a lot more vivid and there is no lag in web browsing. These products are a little pricey but they are sure wort it to me and family

This modem is exactly what I needed… I’m paying for 2000/300 download/upload and am getting all of it. I have been Xfinity customer for long time and didn’t want to switch to other services… I am very happy with this modem.

Works extremely well with Spectrum 1000 mbit plan. I have had 0 issues in the first month of using it. Would highly recommend if you need the speed. Make sure you get the CM3000 and not the CM2000. If you have all 2.5 gbit connections between modem, router, and computer you can get 1.2 gbit from the 1 gbit plan from over provisioning.

So far had for 24 hours this is a awesome modem so far i have had no drop in signal no lag everytime i wanted internet it i had it game reduced to no lag the cm3000 is fantastic this is one of the best modems i have had so impressed all i can say is netgear has really fixed the issue from the past madel and this is great hats off love it no more resetting modem so impressed

Easy to set up, works well, app is intuitive, overall a great purchase.

Great modem with fast speeds and easy setup and connections

Excellent modem. No loss of signal or cutting out. Fast, easy to connect.

I recently upgraded my Xfinity plan to 2Gbps. My existing modem, despite advertising with handling 2000Mbps speed, couldn't handle my new internet plan. I purchased this modem, as Xfinity stated this was on their "Next-Gen Speed Tier" list. I plugged it in, followed the Xfinity app's instructions, and viola! Am getting 2.3Gbps consistently!! A bit pricey though...

I have Xfinity for my high-speed Internet. Xfinity did an upgrade in my neighborhood, so I needed to upgrade my modem to this model. I am getting much faster download and upload speeds.

For the most part, I’m noticing a slight improvement in connecting to Xfinity with 90% download/upload capacity. Overall, I believe this Netgear model is of high quality and performance. Xfinity Internet is the usual culprit behind all my connection and speed issues.
