Motorola MB8611 vs Netgear CM2000: Detailed Comparison

Before I came up with this comparison, I individually tested and used both devices for months. I know their ups and downs very well and will put my honest views below.

If needed you can read their individual reviews:

Key Takeaway (Spoiler): Netgear CM2000 is a better choice than Motorola MB8611, as I faced frequent disconnects with MB8611. Some of the users also face firmware-related issues. So, CM2000 is definitely worth the extra money.

That said, let’s get into the details.

Tech Stack

Technically, both are among the top-rated DOCSIS 3.1 modems with a similar maximum speed capacity of 2.5 Gbps. Not only that, both are backward compatible with DOCSIS 3.0 to support maximum internet service plans.

Other than that, both entail the latest IPv6 technology alongside features like low latency mode, low power mode, and turbo modes for gaming.

Tech-wise, there aren’t many differences, so you can expect an almost equivalent performance from them.

Speeds & Performance

As mentioned earlier, DOCSIS 3.1 and a maximum speed cap of 2.5 Gbps mean both have the capability to deliver ultra-fast speeds, provided you have a viable ISP. However, the real-time values might tell a different story.

I paired Xfinity 2 Gbps plan and measured download and upload speeds for both:

For Motorola MB8611, the respective values fared at 1.85 Gbps and 147 Mbps, while it recorded 1.97 Gbps and 169 Mbps for Netgear CM2000. And the wired connectivity with the 2.5G port delivered excellent results for both.

The primary reason was poor firmware optimization in Motorola MB8611, resulting it lacking in the ability to rapidly process the data sent back by the router. Lately, I even faced frequent disconnects, leading to a bad experience.

Ping is important when playing online games, streaming high-resolution media, and web browsing, but gaming hits the worst. So, Netgear CM2000 is a better choice for high-ping involving tasks, especially gaming.

ISP Compatibility

Regarding compatibility with internet providers, both MB8611 and CM2000 support the major ISP providers, including Xfinity, Cox, and Spectrum. But the latter takes the edge by delivering additional compatibility.

Design & Port Setup

Design is the differentiating factor between the two DOCSIS 3.1 modems. Although the port setup is the same, the shape, form factor, shape, and aesthetics of the two are completely different.

Motorola MB8611 Front Look

Motorola MB8611 boasts a minimalistic design with rounded corners and a small footprint. Besides, there are colorful LEDs in the front, which gives the modem a very modern look.

Netgear CM2000, on the other hand rather, looks futuristic with its edgy design. Dimension-wise, at 9.92 x 4.7 x 8.7 inches, it is much larger than its counterpart, which is 7.88 x 7.25 x 2.25 inches.

The modem has more angles and edges around the chassis, making it stand out from others. Besides, it also instills LED lights in the front, but they aren’t as attractive as in the other.

But where MB8611 takes the lead is the mesh side panels that make room for better air passage to dissipate more heat. While a solid chassis in CM2000 with a few gaps doesn’t make it as efficient, I didn’t encounter any performance gaps with it.

Installation and Management

Like most top-tier modems, refreshingly simple and a few-step installation makes them an ideal choice for those who aren’t into these devices much.

Besides that, the respective compatible apps’ simple and clean user interface makes for much easier management.

Hardware & Other Features

Hardware setups of both Motorola MB8611 and Netgear CM2000 are almost similar except for their NAND storage, with 128MB and 256MB, respectively.

Both integrate the same multi-gigabit processor, Broadcom BCM3390V, an upgrade to BCM3390, as seen in the previous modems, Netgear CM1200 and CM1000.

As a result, you can expect a similar performance from both, and there won’t be any major lags or inconsistencies when you are online with tasks like gaming, streaming, and video conferencing.

Frequently Asked Questions

Is the Motorola MB8611 worth buying?

Yes and no. Some units face frequent disconnects and firmware-related issues. However, at around $200, it’s one of the few modems with a 2.5 Gbps port, a minimalistic design, and a two-year warranty.

Is it worth upgrading to CM2000?

Priced almost $60-70 more than MB8611, the CM2000 boasts a much better design with curved edges, solid and matt-black chassis, and better performance and reliability. However, if you are a gamer who also indulges in activities like streaming and video conferencing, MB8611 with AQM support should be fine too.


Comparing MB8611 to CM2000, it’s clear that both are almost identical specs-wise, But the CM2000 turns out to be better. Although not all units face disconnect and firmware issues, it’s wise to invest a few extra dollars and get the ever-reliable CM2000.
