Customer Ratings & Reviews

I bought this on August 16, 2020. It worked fine for 3 weeks and then suddenly my internet keeps on failing. My kids would get logged out from their distance learning and cannot even go online. I have Spectrum 400 MB. If it works, it has crawling download speed of 2-40 MB. I called spectrum 4 different times and they troubleshoot it over the phone but no success. Spectrum tech came in today and did not find any issues with the lines or connection. The issue was this Netgear modem. He replaced the modem and it's back to over 400 MB speed. It was over the 2 week return period per BestBuy so they cannot help me.

Worked fine for a 13.5 months, so out of warranty. I periodically reboot and this time it never came back.

The base could stand to be a bit wider, and also a bit heavier. I'm also a fan of keyholes so that items like this could be hung on a wall. Other than those minor issues, everything seems fine.

This modem worked fine for maybe a week. I would have to unplug it multiple times a day and also reset it after that first week. It was very frustrating since I thought I bought a high end modem only to have issues constantly. I ended up exchanging it for an $80 surfboard and haven’t ran into any issues even though it is the one known for having a bad chip in it. Maybe I had a faulty modem who knows but as of now I am using the surfboard.

Great when it worked, but failed after a few days. Not acceptable for when I am not home to troubleshoot the problem. Went back to my previous slower, but more reliable modem.

Do not buy this. It will last 18 months and then 3 out of the 4 Ethernet ports will stop working.

I bought this as a new unit and it arrived looking new in a new-looking package. Hooked it up and it didn’t work. Called Xfinity twice and paid for one of their techs to come out. He discovered there was a sticker with a MAC address placed over the original MAC address number. We removed it and finally Xfinity could recognize the modem but it didn’t work. Apparently it was defective and someone faked the MAC address sticker for some reason. Horrible experience

This is a well made modem, but it didn’t work well for me. My provider is Comcast and I was able to get it registered. When I was using it there was heavy packet loss with everything I used, around 30 percent. I ended up returning it and renting a modem from the provider.

If you have xfinity, think twice about purchasing this modem. It is not recommended by xfinity and for good reason…too many drops and rwconnection issues

Run don't walk away from NetGear. This modem failed after the 90 day "Free" support. It only lasted 6 months and the network ports all died. When I called to get the "Free" 1 year replacement, I was asked to provide a credit card for $129 support contract. I DID NOT want a support contract. I was then told that I needed the support contract to replace the modem. I now have a useless brick. I will NOT be doing business with NetGear ever again if this is their business model.

I chose this modem because it had multiple ethernet ports. Did not realize that only one can be used at a time. Very annoying.

dud out of the box, i need to use the ports in the back and one works some times tec support is at least an hr wait on hold

Started out with a connection that was equal to the CM600 which is a 4-year older model and a 24x8 channel 3.0. I ended up returning this as the very next day I woke up with no internet and as soon as I called spectrum back and went back to the CM600 my speeds were 230 down and 11.74 up the highest the CM1200 3.1 ever got was 220 down 10.6 up which is very disappointing as this is a 20/20 model and what the CM600 is probably a 2014 model. Obviously they haven't improved much and I have it paired with a r7400 Netgear nighthawk router which runs flawlessly

Died after 13 months. Worked good until it started dropping the connection intermittently, then it dropped it for good.

Bought this December 31, 2020. Today, the 7th of April 2021 it finally died after being unreliable for a couple of weeks. Seemed to work fine for a couple of months, but come to find out the older model Arris modem I replaced it with is also giving me a faster connection. Hard to understand how the same company that makes great home network/wifi routers, NETGEAR, can sell such an unreliable modem under the same Nighthawk brand name.

DID NOT LAST AND HAD TO RETURN, I RECOMMEND JUST GETTING IT FROM THE SERVICER YOU USE A MODEM FROM THEM.

Brand new modem olnly good for 10 months. Netgear will only give you 3 months of troubleshooting. Netgear will not take a lost on nothing even on return products. Netgear is all about the money they can get out of you. And best buy should at least be able to swap this item for up to a year. Not netgear or bestbuy will lose. Just the cuatomer.

While it’s a great unit, for the price it’s just too much for such little performance gain.5

This modem lasted 16 months before refusing to connect whatsoever. Even when the cable tech connected directly to the modem, it refused to send the appropriate signals. Of course, the warranty is already expired, so now I have an expensive paperweight. It appears all of the reviews on here are all shorter term reviews. It was great at first, but these devices should last a lot longer than 16 months.
