Super fast. Easy to replace Comcast’s modem with Comcast app for setting up new device.. Had to restart modem to finish setting up. No more modem rental$. Netgear warranty is for life. If you register with Netgear. Thanks Netgear!

. . . Xfinity just upped my internet speed to 1+ GB, so it was time to upgrade my years old Netgear Modem that was only rated to 300MB. I have a Google Nest router so I didn't need an integrated router. Also have Xfinity voice, so I need those phone inputs. Yes, the CM2050 is expensive, but it works flawlessly with Xfinity. The key - and this is ESSENTIAL - is to download the Xfinity app. I plugged in the MAC address from the modem into the app, hit SEND and I was up and running in 10 minutes. Downloads are 900MB, upload 40MB. Very satisfied.

So happy to return Xfinity’s equipment and replace with this and eero pro. I’m finally getting the high speeds I am paying for. It’s been six months and I haven’t had a single problem. The X1 modem/router was so unreliable. The new system is A++++

Had The Geek Squad replace the combination Modem / Router from Xfinity and saw an immediate improvement in performance and stability. Paired the Nighthawk with a mesh router and highest speed internet and I’m ready to cut the cord!

I purchased this Netgear Cable Modem on sale $50 off and compatible with my xfinity service. In the future I might need a faster 2Gigs of hi speed connections. So far so good!

I have had unit for a few weeks now set up was easy and works great with Xfinity phone service. would highly recommend for system upgrade and you will save money by not paying Xfinity for their modem.

Needed to replace my ARRIS surfboard modem as it couldn't go above 650mbps. This modem is phenomenal, hasn't skipped a beat - activated easily with xfinity, and I haven't needed a single restart. Works really well with other Netgear products - especially Orbi as the router,

This modem works well if you need voice capabilities.

I purchased this device to be compatible with my high internet speed plan at Xfinity. I'm happy with the purchase, it's an easy set up, and much higher internet speed

This was the only option since I have a cable phone and I did not want a modem / router combination. Setup was very easy and this modem is much faster than my old one that was leased through the cable company. It is also saving me $14 a month in lease fees to the cable company.

It works, but it’s not worth the hype or price. Speeds are fine when it feels like cooperating, but I’ve had random disconnects that require rebooting more often than I’d like for a $300 modem. Setup was straightforward, but stability hasn’t matched the premium price tag. It’s not trash, but it’s not the rock-solid upgrade I expected either. You’re mostly paying for the Nighthawk name and future-proofing with DOCSIS 3.1, but don’t expect miracles if your ISP is mid-tier or your signal isn’t perfect. Decent, but not impressive.

Avoid this modem if you want upload speeds beyond 50Mbps, currently it is not compatible (March 2025). We purchased this unit thinking the claimed 1G upstream meant it would be capable of faster uploads when Xfinity/Comcast made that available in our area. The faster uploads just recently became available in our area but the CM2050v is capped at 50Mbps (Comcast confirmed this to me). We found out the hard way after upgrading to the Gigabit X2 plan and spending hours trying to get the modem provisioned properly. The download speed is present, but our upload tops out at 42Mbps. It appears this was done on purpose by Comcast (after discovering a bug, the firmware was rolled back). This 'bug' has been worked on by both Comcast and Netgear for over a year (their own claims), and there has been no solution. It appears that the only other Voice equipped unit that can do the faster tier upstream is their own rental modem (which I would also avoid for a multitude of reasons, not just the rental fee). Best of luck !

Much better than Comcast modem/router, which regularly needed reset and caused streaming devices to often buffer. This modem consistently measures, using Ookla Speedtest, at 930Mbps on computer connected by ethernet cable. Now no devices experience buffering.

Replaced my old Arris modem that kept slowing down. This Netgear modem is rock solid. It hasn't had any issues with losing connection and consistently delivers over 1 Gb connection. Easy to set up and only took 10 minutes to get my Xfinity service back up and running.

The Nighthawk cable modem is working great. Once it was set up, there are less issues with the older versions.

Used it to replace 4 yr old modem I thought may be causing dropped calls. Easy to install, and it solved the dropped call problem. I recommend it.

Easy setup, Works as promised. Higher speed than the Xfinity-supplied device. Silent. Indicator lights are useful. Altogether a good device.

Very easy setup. Excellent performance My father is older and not very tech savvy. This purchase seemed a no brainer as far as convenience and performance.

This modem is one of the few approved by Comcast/Xfinity if you do not want to use their equipment and also have a landline. I like Netgear equipment in general so was happy it was one of the choices. It was easy to setup following the included instructions although you do need to download the Xfinity and Netgear apps on your smartphone. Performance is better than expected and I am now getting over 900mbs download speed over a cat 5e cable. I also purchased the Netgear Nighthawk AX5 AX4200 Router when I upgrade to this modem.

Now that I have the modem in place 2 month later it works great. However, it took a failed install by me, failed install by xfinity on line assistance, failed install by a tech at my house, and then reprogramming in the xfinity system so that i could finally install the modem 2 months later.
