Review: Big improvement so far! - Modem seems to have stabilized my setup. I’ve been having issues with our Motorola MB8611 this is replacing. So far everything is staying connected and I’m no longer seeing modem resets multiple times a day with our xfinity internet. So far so good, will update in the future once I have more time with the device. This device also unlocked higher upload speeds for us, I have included a photo for reference. This is paired with an Orbi RBK963 system and is working flawlessly.

## Questions & Answers

**Q: Why does it say 4x ethernet ports in your description where there is only one**
A: Actually, because Amazon shows the same questions/descriptions for multiple different products.  The CM1200 has four ports, the CM1000 has one.

**Q: With the cm1200 and xfinity residential cable internet, can you use one wan port to your computer for a direct connection and on wan port to router?**
A: Both the CM1150V and CM1200 have 4 Ethernet ports. That does not mean you don't need a router. These four Ethernet ports support future multi-gig services by using link aggregation and two or more different IP addresses. The CM1100 has two Ethernet ports for the same purpose of future link aggregation. If you want a multi-gig cable modem (2.5 Gbps) without the need for aggregation, you'd like the CM2000 or CM2050V with XFINITY voice support. I know NETGEAR does not do a very good job explaining this to potential buyers and I hope this helps someone.

**Q: So, up to 2gbit modem with - drumroll please - 1gbit network ports. not 2.5gbit. which engineer was responsible for this fail?**
A: which "engineer"?  It was probably "beancounters" in marketing.
this CM1200 model has 4 ethernet ports.  but only 2 are functional.
the first 2 ports can be Link Aggregated, to get downloads up to 2 Gbps.
the other 2 ports are mere decoration to trick naive trusting people to buy this model.
not to overlook, Netgear only certifies this model to 800 Mbps with Xfinity.
that's what it says here in the ad.  (and also on Netgear website)

**Q: Can I replace my existing cable modem from Spectrum with this, on my own/ without a service call or having to call customer service?**
A: Replacing your modem does not require a service call, but you will need to call Spectrum customer service, as they will need to activate the modem as an authorized device on their network before it will be able to lock down a connection. You will need to provide them with the unique MAC address of the device - specified on the modem's label. Customer service calls can be irritating, but when I did the same a month or so ago, the tech knew what needed to be done and the entire call, once speaking with the tech, lasted about 5 minutes - little hassle...this time.

### ⭐⭐⭐⭐⭐ Great Modem
*by J***P on December 22, 2025*

Great modem. My internet speed increased to what it should be after setting up this modem. Very easy to set up with my internet provider.

### ⭐ Worked great until it didn't
*by A***X on July 5, 2024*

This modem worked great until the multi-gig function inexplicably stopped working after only a year and a half. Now instead of getting the 1000 Mbps I pay for, I am capped at 100 Mbps. I did not touch the thing the entire time, it just stopped working. I have tried replacing all cords, reset everything, and nothing has fixed the issue. Which made me look into updating the firmware and had me discover that Netgear is a scam. They expect you to pay extra for any amount of tech support. Meanwhile they claim they are unable to update the firmware. So I talk to my ISP (Mediacom), and they claim they are unable to update the firmware and it is the manufacturer who can do that. So back and forth I go between Mediacom and Netgear who both say they can't update anything and that the other should be able to. So here I am with wasted time, wasted money, and a $300 box that can't even put out a wireless signal on its own. This modem is too expensive to not even last 2 years at full functionality. Why does anything related to connecting to the internet have to be the most painful process in all of tech
