Customer Ratings & Reviews

Have Netgear Nightghawk 9000 along with this docsis 3.1 modem with voice. This modem is extremely stable compared to any of the previous Xfinity modems I had to rent from them. Simple setup and admin page is easy to navigate. Ditch renting you will never look back!

I replaced my Xfinity modem with the Nighthawk & am pleased. The modem works well in combination with my Orbi satellite system. Set-up was surprisingly quick.

This is my second nighthawk-first strickly cable modem. Much faster than my preious one and works flawlessly with my eero mesh wifi system

So far so good. Thinner then the older one. Easy to setup if you know what you are doing

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.

Setup went very smoothly no problems, modem working great.

This modem works well if you need voice capabilities.

I upgraded to this CM2050V from a very old Arris telephony model and I have been pleased with this modem’s performance. I also like the sleek design and vertical orientation of the modem. Setup was a bit problematic since the modem would not lock a downstream channel, and the tech support agent from Netgear was essentially useless, but I eventually isolated the issue to my UPS coaxial connections (not sure why it was interfering with things because it worked fine with my Arris modem) but I simply connected the modem directly to my cable wall outlet and it locked a downstream channel just fine and my internet speed stabilized. The aforementioned Netgear tech support agent told me it was normal to not lock a downstream channel and the LED blinking for the downstream channel was normal too (the agent completely contradicted the user manual and followed an obviously scripted troubleshooting procedure delivered with no independent though). Overall I think this was a sound upgrade.

Works great. Extremely fast! Easy to set up and start surfing!

Easy to provision with Comcast, happy with the performance, happy to not be paying a monthly modem rental fee! If you're running your own Wi-Fi router and just need a modem that gets the fastest speeds, this is a great pick, I use this to drive my Unifi Dream Machine Pro and it works perfectly.

This was easy to setup and required only a phone call to Comcast/Xfinity to switch over from my previous Comcast/Xfinity Gateway to this new modem. Granted I had to spend 30 minutes on the phone with Comcast while they updated everything on their end but it was painless. New modem works great.

Took a bit of time for the unit to update and register with Comcast. One thing the instructions don't suggest is to plug the modem directly into the computer, without a router, get the unit registered with Comcast and then, once that is stable, work on your new router (I bought a new Nighthawk RAX70 with this modem when I replaced my Motorola MT7711 Data and Voice modem/router). Once all set up, my speed on downloads increased by over 150 Mbps, and my uploads increased by about 10 Mbps. The Motorola had good range, but the new RAX70 had 3 bars for WIFI signal two houses away. Definitely do the "Try Again" a couple of times with the Netgear app when registering, as there is some definite software updates and handshaking going on in the background as Comcast searches for your device, the device updates and all the processes complete themselves. Be patient and it will be well worth it once done.

Excellent device if you Gbp speed service from your provider and a router that has 2.5 Gbp port. 2 phone lines is a plus. Paired with Netgear RAXE router connected to routers 2.5Gbp port which led light is blue when hooked to 2.5Gbp port. Simple plug and play. If you want speed and that's what your system is built for I highly recommend.

Blazing fast speed and reliable data stream. Rarely ever have to reset this modem. We had to reset the modem supplied by WOW often. We have this paired with a Nighthawk high power router and they work well together. Very happy with this purchase.

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!

Purchased this modem to take advantage of Xfinity 2.5Gig internet service. Within 20 minutes of opening the box I was up and running with my service showing the advertised speed.

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.

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!

. . . 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.

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!
