Netgear CM1000 Review

Netgear, without a hint of doubt, sets higher standards when it comes to networking devices. And while most of their products are show-stoppers, the CM1000 goes one step ahead by being one of the top Gigabit cable modems.

Still, I wouldn’t advise you to take my word for it. Instead, I suggest reading further to learn about its performance and capabilities.

Netgear CM1000 Review: After 3 Weeks of Use

Stacked with the latest standards, this Netgear modem outpaces its close competitors such as ARRIS SB6190 and Motorola MB8600. And that is exactly what I shall validate in the subsequent sections.

Also, just so you know, I tested the Netgear CM1000 as my primary modem for over three weeks, using it with a TP-Link router.

Netgear CM1000 Speed

When paired with Xfinity's 800 Mbps plan, the cable modem complemented the TP-Link Archer AX55 router with exceptional speeds.

Coming to the numbers, at 30 feet from the internet equipment, my MacBook Air witnessed 782 Mbps of download and 33 Mbps of upload speed.

Netgear CM1000 Speed Test

Moving the testing device further at 60 feet, the speeds were dropped. Specifically, the download clocked 151 Mbps, and the upload reached 19 Mbps. These are still good enough and could handle most activities at hand.

I could play games, stream TV, while browsing on multiple devices, and also handle some of the smart-home gadgets. Performance-wise, I have no complaints, the device works as intended.

Compatibility with ISPs

Talking about ISPs, the Netgear CM1000 works swimmingly with most cable internet providers in the United States. Also, Netgear suggests pairing it with internet plans up to 1000 Mbps.

Here's a list of compatible internet providers along with their ideal internet plan:

  • Cox Residential — Gigablast
  • Xfinity by Comcast — Up to 800 Mbps
  • Charter Spectrum — Internet Gig
  • Mediacom — Up to 1 Gbps
  • Optimum — 500 Mbps
  • WOW Internet — 1 Gbps

Ports & Connectivity

Netgear CM1000 Ports

Netgear made sure that you mostly have to rely on a router to make the best use of the internet plans. The solitary Gigabit LAN port justifies the same. However, if you look at the rear panel, you will notice that the slot for coaxial cable is present, as expected.

If you only have one device to work with, you can establish wired connections and get up to 1Gbps speeds without breaking a sweat, provided the ISP permits.

If you wish to learn all the differences between the two, here's a detailed comparison between CM1000 and CM1100 to help you make an informed decision.

Design & Build

Netgear CM1000 Design

The CM1000 assumes a vertical form factor with dimensions fixed at 8.8 x 3.5 x 5.9 inches. Also, it is one of the few perfectly-ventilated modems in the market, and that too with a basal stand in place.

It weighs less than a pound and involves hardened plastic as the underlining structural material. Plus, there are 5 LEDs in play for indicating network conditions.

Hardware & Technology

Driving the Netgear 1 Gig modem is a powerful multi-core chipset. And even though Netgear hasn’t declared other hardware-specifics, you can expect the power-efficient processor to work alongside 512MB of RAM.

Moving further, this is one of the best-rated DOCSIS 3.1 modems with support for 2 x 2 OFDM/OFDMA channel bonding, making it future-proof and ready for multi-gig speeds.

However, the most promising aspect of this networking device is the DOCSIS 3.0 backhaul, with 32 x 8 channels to work with.

And for gig-level connections, DOCSIS 3.0 is more than sufficient. Adding to this is the built-in QoS support that enhances the wireless capabilities of the router that you wish to pair with this modem.

Netgear CM1000 Setup

Setting up and activating the CM1000 cable modem is fast and easy. It also comes with a setup instructions manual that's easy to understand.

Finally, it supports the IPv6 protocol to make configuration quicker and the Quality of Service functionality more impactful.

Netgear CM1000 User Reviews

I was in a situation where my rented Xfinity gateway was piss-poor with the high-speed plans, and invested in this mid-range Netgear CM1000. Pretty happy with the performance.
Ella M
Replaced this over my Cox modem, and immediately noticed the upgrade. I could just sit on my couch and enjoy movies on Netflix throughout the day without any bottlenecks, making it a reliable offering.
Andrew N
This is my first time with a non-rented modem, but its ease of setup and friendly tech support helped me throughout the installation. The app is super functional and also is impressed by the speeds I got.
Zoey P
Would give 4 out of 5 stars to the cable modem. I cut one star for the weakened performance over a distance. But the rest is fine.
Willie V
I got CM1000 after reading this review and I am well satisfied. It performs great with high speeds, supports multiple ISPs (in case if I need to switch a provider), and installation was simple.
Anthony K
This slender-looking modem with ample ventilation helps it stay cool even after continuous heavy usage. Besides, with its minimal design, I don’t have to bother about making much space for it on the table.
Alline R
Aside from its decent performance across all fields, I find its single ethernet port as a shortcoming. I wish it came with at least one additional gigabit ethernet port.
Everett E
I was in awe with its core that combines a multi-gig processor with 512MB RAM and decent flash memory to give my device experience a performance worthy of mention.

Frequently Asked Questions

Is the Netgear CM1000 a modem-router combo?

No, the Netgear CM1000 is a standalone modem that needs to work separately with a router to offer wireless capabilities. And a gigabit LAN port actually comes in handy if you want to pair the modem to the WAN port of the router.

What is the built-in QoS associated with CM1000 used for?

The associated Quality of Service allows the modem to prioritize traffic to the devices that want it the most. With QoS on offer, the modem powers the best quality of transmission to the router and lets the wireless device take it from there.

What are the max internet speeds supported by the CM1000?

The CM1000 can easily support max speeds of up to 1000Mbps, provided you have Cox or Spectrum as the preferred ISP. For Comcast Xfinity, however, you might only be able to churn out 800Mbps at max. I tried connecting it with a Gig-internet plan from Xfinity, which maxed out at 750Mbps.

Verdict

The Netgear CM1000 might not seem like much, but it is a highly resourceful modem. Led by the best DOCSIS standard and a high-speed Ethernet port, the device is minimally effective.

And making things better is the affordable pricing that further justifies the faith most of us have in this modem.
