NETGEARNighthawk Cable Modem CM1200 - Compatible with All Cable Providers Including Xfinity by Comcast, Spectrum, Cox | for Cable Plans Up to 2 Gigabits | 4 x 1G Ethernet Ports | DOCSIS 3.1, Black

If you have Xfinity, if you have a phone or tablet connected to the internet through 4g or 5g, you can ignore the instructions in the quick start guide telling you to connect a laptop to the modem to activate the modem. You only need to do this if you have no other way to connect to the internet. Before you disconnect your old modem and router, download the Xfinity app from the app store onto your mobile device. Then, turn Wi-Fi off your mobile device, and proceed to disconnect your old modem and router. Navigate through the Xfinity app to add a device or replace your equipment. Follow-the instructions and your new modem will be "activated" to your Xfinity account.

It was easy and smooth installation process as an Astound customer. I only need to contact the service provider to connect with the modem. No compatibility issue.It has higher speed than my previous Netgear CM500 Cable Modem @ 680 Mbps. Now it is at 850 Mbps range. The size is small and time will tell if it is durable. Will update if it has a short life.

Been working from home for close to 2 years now on a personal device. The company I work for shipped out their own computers and we have been switching to only using the company devices. I paid for the highest possible internet speed from Comcast Xfinity, but the company computer kept freezing every five seconds and was impossible to use. Comcast continuously came out to the house and told me to my face that there was absolutely nothing wrong with the internet and that the problem was the company computer.I replaced the modem provided by Comcast with this Netgear modem, and suddenly everything was fixed, and the company device worked smoothly and I didn't have to worry at all anymore.SHAME ON COMCAST for making me believe that nothing could be done.THANK YOU NETGEAR for SAVING MY JOB THAT I LOVE AND AM GREAT AT. Thank you.To anyone who has Comcast Xfinity - TOSS OUT THEIR BOX OF EVIL and BUY THIS NETGEAR MODEM.

LAST UPDATE: I now have Frontier Fibre Internet. I sold my cable modem and it was still working great when I did. I am still using the TP-Link Deco x20 (x3 nodes backhauled) and my network has been rock solid all along. I still will never go Netgear again.UPDATED REVIEW: TLDR Listen to Reviews, Horrible Customer Service, 90 Warranty ONLY - You Have Pay for Anything After that! Garbage Equipment. Had Two of these Die!!I should have listened to reviews of this CM1200 Cable modem! First modem I got was garbage and after a month of trying to trouble shoot why my new network setup was't working, it turned out to be the modem. So I got that one replaced with a like kind CM1200. Worked OK for the 5 months I've had it, but I didn't realize what torture I have been living with by doing every other day restarts until the unit completely crapped out. Intermittent dropouts of network connectivity, constant reboots of the modem to get it connected again, which progressively got worse and worse until I had to restart the modem at least every 2 hours just to have connection again. I finally got to the point where i bought a competitors modem (Arris SB8200 Cable Modem Only, and LOVE IT!) and I have been actually sleeping at night again. I literally had dreams at night that the network was down and I had to get up to get it working and couldn't. Never lost sleep over something so ridiculous before, but I did. I've had my SB8200 high speed modem for two weeks and its a joy to come home and not have to hear my kids tell my that the internet has been out again for the last 4 hours.Never again Netgear; you have burned me for the last time. ON TOP OF THAT, the whole pay for service on a product that is less than a year old is INSANE!!! This was the service call:"Hi whats your problem""My modem is losing constant network connection.""Is the light on for etc, etc, etc, etc?""Yes, they are all on at the moment, but after a couple of hours, I lose connection even though the lights are on.""Oh, your equipment is fine, so it's not that. But if you want to purchase a service agreement we can forward your issue to our troubleshooting team...."CLICK.... I hung up on that B.S.!WTH is that!!! Company essentially holding me hostage with a $180 piece of garbage paperweight and they wont honor a one year warranty on unless I pay for a service contract. Absolute crap I tell ya. Never again Netgear, never again. I said never!! Stay away from this product, and essentially any of their others. I've had a gaming router of theirs before too, and it had similar issues that I replaced that with a TP Link Deco x20 Mesh Router, and it work awesome. Just dont buy these guys crap, you will regret it in the end.FIRST REVIEW: So the first cable modem I got had to go back. Constant internet drop outs, restarts, reboots, start over! It was a headache for two weeks trouble shooting. I had upgraded my internet service, cable modem and then mesh routers within two weeks. The cable modem/service were first and connection was intermittent. So figured it was my older gaming router and I needed mesh network upgrade for the house and kids demands for connection. Replaced with wifi mesh router and it was a crap shoot for many days. I thought the new router was no good, but then I got a replacement cable modem to rule that out. Turns out my Cm1200 was bad. The replacement has been working great and now I have to update my review on the Wifi routers that I lambasted. Knocked off one star on this cable modem due having to troubleshoot and replace the original purchase. But so far so good. Hope it stays that way.

Does what it’s supposed to. Battery life is good. Signal is good. Quality is good. Haven’t had to reboot. It is compatible .

ISP change their coverage and the old cable modem started to drop out randomly always at the worst time. This one has been in service for more than two weeks and the problem has vanished. Nice configuration and the speed should cover us for a couple of years.

The modem works perfectly with comcast. Even though I had to pay a little extra up front this is a net saver when it comes to cable company rental fees. Have had zero issues using it.

Easy setup, speed is excellent, I been debating on getting my own modem for a long time. I finally did and it was def worth it. The free modem that you get always have issue, and always end up breaking. Its affordable if your debating getting your own modem just do it.
