#2. Motorola MB8611 DOCSIS 3.1 Multi-Gig Cable Modem - Best Multi-Gig Modem

Important Specifications

  • Brand: Motorola

  • Internet service provider: Comcast Xfinity, Cox Communications, Charter Spectrum, RCN

  • Connectivity Technology: Ethernet, WiFi

  • Compatible Devices: Personal Computer

  • Item Dimensions LxWxH: 7.25 x 7.88 inches

Product’s Highlights

With 32 x 8 channels, AQM technology, and a 2.5 Gbps ethernet port, the Motorola MB8611 is a highly capable DOCSIS 3.1 modem suitable for Gigabit and Multi-Gigabit connections. The Motorola MB8611 DOCSIS 3.1 modem is an excellent choice if speed is a top priority. It is optimized for high-speed connections of several gigabytes.

When it comes down to brass tacks, this is one of the few high-speed cable modems on the market that is ready for high throughput, future-proof internet plans.

After putting it through its paces on a 1000 Mbps internet connection, I could observe how well it handled traffic, handled congestion, and achieved its stated throughputs.

MB8611 isn't just about the speeds it can handle, though. Rather, there are a number of inherent and physical factors to consider. In the following sections, I will review every feature and aspect I discovered regarding Motorola's premium cable modem.

#3. ARRIS Surfboard S33 DOCSIS 3.1 Multi-Gigabit Cable Modem - Best Warranty

Important Specifications

  • Brand: ARRIS

  • Internet service provider: Suddenlink, Xfinity, Cox, Mediacom, Spectrum

  • Connectivity Technology Ethernet

  • Compatible Devices: Router, Personal Computer, Ethernet connected devices

  • Item Dimensions LxWxH: 5.14 x 1.8 x 4.74 inches

Product’s Highlights

The Arris SurfBOARD S33 was tested with a number of major cable internet service providers and was found to be a reliable DOCSIS 3.1 cable modem.

It's easy to be deceived by its little stature and mild appearance. Don't take this modem lightly. The fastest cable internet plans will have no trouble being handled by its one 2.5 Gbps connection and secondary Gigabit port. The SurfBOARD S33 doesn't resemble a Nighthawk modem in appearance, yet it functions identically to one.

It has you covered on all fronts with its two LAN connections. Your Internet service provider or package must allow for two static IP addresses for you to use both.

Each of the 2.5 Gbps ports can support download rates of up to 2,500 Mbps, making them ideal for high-speed internet connections. That includes the fastest cable internet options on the market right now.

There does not seem to be any link aggregation at this time. This means that each Ethernet port provides its connection and cannot share data with other ports.

It's important to remember that just because the S33 is capable of such speeds does not guarantee that you will experience them.

Things to Consider

  • Confusing status light

  • Design is not for everyone

#4. ARRIS SURFboard SB8200 DOCSIS 3.1 Cable Modem - Best for Comcast Xfinity

Important Specifications

  • Item Weight: 1.43 pounds

  • Product Dimensions: ‎5 x 2 x 5 inches

  • Color: White

  • Batteries: ‎1 Lithium Ion batteries required.

  • Manufacturer: ‎CommScope

Product’s Highlights

ARRIS claims that its SB8200 can accommodate 1 Gbps cable internet plans. But in real-world testing using an active Xfinity Gigabit connection, I was able to get download speeds of 750–800 Mbps.

Thus, this model cannot use Gigabit internet plans to their fullest extent, unlike the ARRIS SURFboard S33. Check out the gigabit modems I suggested if you want actual Gigabit throughput.

However, the speeds were stable, and I was able to access the web from my notebook, my office computer, my smartphone, and the devices hosting my smart home and security cameras. Even though I could only upload at 35 Mbps, I could still download at up to 800 Mbps, which was more than enough for me. I used that time to catch up on TV programs, play video games on my PlayStation 4, and engage in other data-intensive pursuits.

What We Like

  • Two Ethernet ports

  • 32 x 8 channel bonding

  • Link Aggregation support

  • Supports DOCSIS 3.0 fall-back

  • Excellent price-to-performance 

Things to Consider

  • Doesn’t support Gigabit speed

#5. NETGEAR Nighthawk Multi-Gig Cable Modem CM2000 - Best High-Speed

Important Specifications

  • Brand: NETGEAR

  • Internet service provider: Xfinity, Cox, Spectrum

  • Connectivity Technology: Ethernet

  • Compatible Devices: Router

  • Item Dimensions LxWxH: 9.92 x 4.7 x 8.7 inches

Product’s Highlights

There is no muddled port configuration on the Nighthawk CM2000. A single coaxial connector and a power input are provided initially. But the star of the show is the 2.5 Gig ethernet connector, which lets you take full use of the multiple gigabit transfer rates.

Netgear Nighthawk CM2000's multi-gig port lets you connect many devices at once through fast-wired connections. However, a Wi-Fi 6 router should be connected to this modem for optimal wireless performance and to ensure that the network infrastructure can accommodate future needs.

The Netgear CM2000's integrated multi-core CPU collaborates with DOCSIS 3.1 networking technology to provide stable transfer rates and throughput. With 32 x 8 channels in both directions, you can eliminate ping spikes and maintain stable transfer rates regardless of how demanding your online gaming session becomes.

Put on your reading glasses since I've broken up this review of the Netgear C7000 into many parts.

The Nighthawk C7000 takes on a vertical layout, just like the Motorola MG7550, the Arris G34, the Arris G36, and every other combo device I've used or reviewed recently. This device is made out of durable black plastic and has an impressive array of front-facing LED lights.

The Netgear C7000 is compatible with almost every major cable provider in the United States. If implemented, it would work with Xfinity, Cox, and Spectrum's high-speed internet packages. While reviewing the C7000, I used a 500 Mbps Spectrum internet plan for my real-world speed tests.

FAQs

Can I get an Xfinity modem separately?

In order to use your own modem with your Xfinity Internet service, you must purchase one that is compatible with Xfinity's network. Find the right modem for your Xfinity Internet package by consulting the compatibility table above.

best cable modem xfinity

Does Xfinity (Comcast) sell modems?

Xfinity's xFi Gateway (a modem/router combination) may be rented for $14 per month, but buying one will save you money in the long run.

Should I buy my own modem and router for Xfinity?

If you don't want to spend $14 a month to rent a modem/router combination from Xfinity and you're prepared to pay a lump amount upfront for savings in the long term, you should purchase your own modem and router.

Customizing your home Wi-Fi network is a breeze with the Xfinity xFi Gateway and the Xfinity app, but renting may become pricey. High-speed modems and routers, however, are noticeably more expensive than slower models. Renting from Xfinity might be more practical than purchasing your own equipment if you have the Gigabit plan.

Final Words

There are many Xfinity-compatible modems available, but the best cable modem Xfinity is an especially good fit for certain packages. Find the right one for you and enjoy Xfinity's great service every month without paying a dime for a leased modem.
