Get a proper setup….

Reviewed in the United States on January 13, 2024

Interestingly, after I purchased this and called the Internet company for set up, this thing did not really work well. It was connected to my Wi-Fi router, but the signal kept dropping all the time, which was very frustrating.
I called Netgear support and told them, and they helped me set it up…. Or so I thought. However, we still had tons of connectivity problems. I had to call back a second time to get help. At that time it was mentioned to me that I could get Netgear phone support for about $25 for two years… so, I opted to get it. They probably set the poor support up, initially, so people will subscribe. But, oh well. After the second call to Netgear, we still continued to have problems…. So I called the special cust. service number they gave me.
Interestingly, you get what you pay for. When I called this special number, now that I was a subscribed customer, I got a far-superior level of technical support. Come to find out the previous people lied to me, saying my Netgear router was up to date. The guy that I dealt with took care of everything… i mean everything. He changed the an amazing amount of options, and went over everything with a fine tooth comb.. turns out my router was so far out of date, he had to do about 20 updates manually to catch it up. my Internet is now flawless and stays connected all the time.

CM1200 Provides Intermittent Signal - Inconsistent Mpbs, Mostly < 100 Mbps & Frequent < 50 Mpbs

Reviewed in the United States on August 29, 2020

I purchased the CM1200 in August 2020 and received it 8/8/2020. I attempted to connect the device at home as it was replacing the CM500. I have an AC1750 Netgear router that was connected to the CM500 and is now connected to the CM1200. I spent 5 hours the first night working with Netgear and my ISP (Comcast) to setup the device correctly; I was unable to use the activate link and had to call Comcast. While on the phone, Comcast stated because it's a Netgear product, Netgear would have to provide the firmware. However, Netgear's knowledge base states Comcast actually pushes the firmware. It started to feel like I was in the middle between Comcast and Netgear. This should have been an easy experience - plug and play - just like I have done with many other computer hardware.

Once the device was setup, it worked well for about a week. The following Sunday I contacted Comcast again because I no longer was getting internet service. Comcast could not see the modem. We went through normal troubleshooting of a power cycle of both the modem and router. Internet service resumed. A little later, Comcast could not see the modem again. Went through the same steps and it was back.

Comcast sent a technician out on 8/18/2020. They changed connections outside of my place. Also pushed all the service to one cable connection in my place; all other cable wall outlets do not have cable as I'm trying to ensure all the service is going to where I am connecting my internet and TV (I've been in this place for 4 years and did not have this problem previously until recently).

The following Sunday I contacted Comcast again and went through the same steps. The following days I had to restart my modem each morning because I no longer had wifi when I got up to start work. I contacted Comcast 8/27/2020 to further discuss the issue. The first time we went through the normal steps of trying to restart the modem, unplug the modem, attempt to make a connection from Comcast to the modem, etc. Internet service came back... for an hour. An hour later I contacted Comcast again and they pointed me to Netgear. Now I really feel like I'm between Comcast and Netgear and no one taking ownership of the problem.

After speaking with Comcast on 8/27/2020, I entered a support case with Netgear. I contacted them on 8/28/2020 because Netgear apparently does not reach out when a case is entered, it is up to the user to contact them after creating a case online. At 4 PM on 8/28, the Netgear technician had me reset the modem, unplug the modem, unplug the router and then reconnect everything. I explained I do this on a daily basis, but went along. When this was done, internet service returned... as expected. The tech said to monitor the internet for the next couple days to see if the problem persists. I told him I know what's going to happen and that I will be contacting Netgear again before a couple days ends. I asked if they could just send a replacement because I've been dealing with this issue for 3 weeks at this point, and he said just monitor the internet service.

At 8 PM on 8/28 (4 hours after reaching Netgear) I was on the phone again with Comcast because internet service was non-existent. At 8:30 PM I began my hour long hold with Netgear following up on my open case stating what I told the prior technician that I would be calling Netgear back because I would no longer have internet service. We went through similar steps, however this time the technician had me change a setting on the router.

I'm expecting I'll once again be contacting Comcast and Netflix on either 8/29 or 8/30 because the internet is no longer working for me.

At this point, I'm caught between Comcast stating that I'm using my own device and they can't support that, and Netgear saying I have 90 days on my service warranty. Meanwhile, I have intermittent internet issues causing me to use my mobile hotspot to work.

I will say Netgear tech support has been pleasant once I get through the queue, but I've been on hold 30 to 60 minutes each time I call and then another 30 to 60 minutes troubleshooting. I've also had to repeat many details along the way when I call, however, so that's frustrating.

I'm hoping this gets resolved, or I'll have to work with Amazon to return the modem and hopefully get a full refund.

May not work with any internet phone sevice if you have Spectrum.

Reviewed in the United States on August 27, 2023

The specs listed do say that it will not work with Spectrum's phone service. When I activated the Nighthawk cable modem CM1200 and my Ooma phone service. I couldn't get internet service. Spectrum's customer service said it they were getting a signal that the modem was working. They were very patient and tried to reboot and other possible cures until I called it a night. Once I got some sleep and thought about the problem I remembered the phone service warning. Yes the light associated with the Ethernet connection for the Ooma was red. Once I disconnected the phone service everything worked as advertised. My last couple of routers have been from Netgear (Nighthawk X6 AC3200 and R6100. To get those routers to work with the Ooma I have had to route everything through the Ooma before the router. It would not consistently keep working if the Ooma was placed downstream of the Netgear device. Right or wrong I was thought my on going problems were caused by updates Since one of the reasons I bought this cable modem was not to have the restrictions imposed by having everything routed through the Ooma I returned the cable modem. My new router (Asus AX6000 dual band RT-AX88U Pro) has no problem dealing with the Ooma being pluged into it. I liked the Netgear routers but they may have been the source of my aggravation.

Cutting Costs, Boosting Performance, Easy to Install

Reviewed in the United States on January 28, 2024

This modem has proven to be a game-changer in more ways than one. After making the switch from renting a modem from Xfinity, this device not only streamlined my internet experience but also significantly lowered my monthly costs. The setup process was straightforward, and the clear instructions provided with the modem made it easy to get everything up and running in no time. I was pleasantly surprised at how user-friendly the entire installation process was, even for someone not well-versed in tech matters.
