What Is The Best Cable Modem?

Motorola MB7420 cable modem is the preferred choice for most users. This modem works with all internet providers (including Spectrum, Cox and Comcast) and delivers high speeds for most people (anyone who has an internet plan that exceeds 300 Mbps). Two-year warranties are twice the length of those for Netgear’s CM500. They also perform well in our tests. Since the CM500 usually costs less than the MB7420, it’s a worthy alternative for bargain hunters.

Netgear’s CM600 is a reliable internet service that offers speeds exceeding 300 Mbps.

Even though cable modems tend to be expensive, they are often part of Black Friday bargains. However, you don’t need to buy modems during the holiday season. We have noticed price drops in many of these top cable modems, so shop around until you find the best deal.

Why You Should Avoid These Things

The Arris Surfboard SB6183 was once our pick for the best cable modem thanks to its solid performance that will satisfy most home internet customers who don’t pay for high-speed service, though this older modem is harder to find these days. Best Buy sells the SB6183 as of writing. You can find the SB6183 on sale at a great price.

At 5.2 x 5 x 2.1 inches, the all-white SB6183 can be tucked unobtrusively next to a router, cable box and whatever other hardware you have on hand. Although the coaxial-cable connector may be a bit too close to power connector, it is likely that you will have to use this only for setting up your modem.

The SB6183 uses a series of small vertical indicator lights. It is very simple and easy to spot. Yellow lighting might be difficult to detect if your modem is directly in sunlight. You can still glance at the SB6183 to determine if there is an issue with your internet connectivity.

Best Cable Modem Vs. Best Router

Home networking equipment manufacturers seem to favour modem-router pairs over separate cable modems. These hybrid devices can be more appealing than a standalone modem or router. You can accomplish two tasks using one device. However, we would advise against using modem-router combinations.

First, let’s talk about the background. Our modem-vs.router comparison will show that they serve different functions. A cable modem brings internet connectivity into your home while the best routers distribute that internet connection wirelessly, so that all your devices laptops, phones, and smart-home gadgets can hop on the internet. If you’re dissatisfied with the reach of your network, it’s a router, not a modem, that you should be in the market for.

It makes sense to keep these two devices apart. If any part of a hybrid device fails, you’re out both a modem and a router. Because routers are able to support new features faster, it’s easier to update individual devices. Modems evolve more slowly, as you can see from the number of older models still available.

Our pick

Motorola MB7621 This modem is the best for the majority. It works with all ISPs and supports speeds of up to 600 Mbps. The MB7621 is widely supported and comes with a 2-year warranty. It can be used for up to eight months before it costs you anything.

Amazon, $90 at Walmart and $80 at Best Buy

Motorola MB7621 is reliable, supports the fastest internet speeds available to the vast majority of Americans, and offers compatibility with just about every non-gigabit plan from every cable internet service provider in the US including Comcast Xfinity, Spectrum (formerly Time Warner, Charter, and Bright House), Cox, Suddenlink, Sparklight/Cable One, and WOW which gives you flexibility if you move or switch ISPs . The MB7621 works well for plans up to 600 megabits per second, because it’s a DOCSIS 3.0 modem that can handle 24 downstream channels and eight upstream channels. There is also a two year warranty.

Budget Pick

Netgear CMS500 for 300 Mbps plans. If you’re looking to save money, this is still the best choice. As long as 300 Mbps is not exceeded by your current service plan.

Walmart $46* $43 Amazon Best Buy $75

America has an average internet speed of 180 Mbps. This depends on which survey you select. Netgear CM500 is recommended if the plan you have falls in this category and you don’t expect to change your plans beyond 300 Mbps. The CM500 matches the ISP compatibility of the pricier CM600, but its maximum download and upload speeds are lower (300 Mbps on the CM500 versus 600 Mbps on the CM600, though Suddenlink certifies it for 500 Mbps speeds). The reliability of the CM500 is well-known, however it does come with a limited warranty.

Because 8×4 modems no longer work well with ISPs, we suggest 16×4 modesms like CM500. We don’t recommend this as it will cost you less upfront but mean you have to spend years replacing your modem.

There are many buying options

Amazon $160*, $150 From Walmart $169 at Staples

If you already have a gigabit internet plan and your ISP allows you to use your own modem, the Motorola MB8600 is the best of the DOCSIS 3.1 modems that are widely available right now because of its relatively low price and its two-year warranty. To get gigabit speeds with most cable ISPs, you need a DOCSIS 3.1 device. Also, the MB8600 works well on gigabit-speed internet networks that are still following the DOCSIS 31.0 standard. Sparklight/Cable One supports both DOCSIS 30.0 (32×8) or DOCSIS 3.1 modems as part of its GigaOne service.

You should not buy a gigabit-speed modem unless gigabit is already available or you are familiar with it. It is not worth paying for DOCSIS 3.1 modems unless your ISP has gigabit service. You may be unable to bring your own modem if they offer gigabit services.

Which Mbps do you require?

Megabits per second (Mbps) are the main determinant of which modem you choose. This number is crucial as it can determine the quality and reliability of your internet service. You will get faster and better internet service if your Mbps is higher. There are modems that can carry between 10-11,000 Mbps. And the higher your megabits count, the better and faster the internet can handle. What you do with the internet and how many of them are at your home will determine how much Mbps your modem can handle.

Video games, streaming videos can be downloaded at speeds of up to 5-10Mbps. However large files and video may require as high as 50Mbps. At least a 50 Mbps modem is recommended. However, many modems can handle more to support a router with heavy-duty functionality and several simultaneous users.

Modems with Data Over Cable Service Interface Specification (DOCSIS) will have this technology. It’s faster than traditional fiber cables and is more reliable. The most recent version is DOCSIS 3.1. However DOCSIS3.0 provides speeds of up 100 mbps. Although there are several ways you can get internet from an ISP, the best is DOCSIS. Most internet users will be able to use a 3.0.

Netgear Nighthawk c7100V

Consumer Score: 82% gave it 4 stars or more This two-in-one has included phone lines, voice control, and more advanced features.

You can make everything easier with voice control. But even if it didn’t have that nifty feature, the Nighthawk C7100 would still easily rise to the top of the router-modem combos. It is a costly package, but it offers amazing speed in an easily-managed package. This modem will be a good investment as it is capable of 960Mbps. While you likely don’t require such bandwidth now, this amount of Mbps means the Nighthawk has speed to spare and will save you from having to invest in a new modem as tech progresses. The Nighthawk has one disadvantage: it is not a dual modem-router. However, the Nighthawk makes up for this by offering two telephone lines that can be used on Comcast. This also means it is not compatible with any other phone service, but only Xfinity.

Arris Surfboard SB6183 Consumer Score: 84% rated it with 4 or more stars. It’s a compact modem, affordable and easy to use.

This surfboard is very popular. But if you are lucky enough to get one, it will be one of your best options at such a reasonable price. The device is very compact and has bright and easily readable lights.

Tom’s Guide appreciated the Surfboard’s 2-year warranty. This is longer than many modem warranties. The Surfboard’s speeds are up to 686 Mb/s, and this surfboard’s cost was well within the range of the average price.

Netgear Cm500

Consumer Score: 98% of consumers gave it four stars or more. Scores are way higher than its price, and it has a clean, sophisticated look.

Although we do not expect that your modem will function as an art piece, some people worry it might be an eye-sore. While this particular model appears sleek and stylish, its shiny exterior could easily become smudgey. It also doesn’t have the best ventilation, so you will want to keep it in a cool, open area to prevent overheating. Overall, however, reviewers at Top Ten Reviews found that despite the CM500’s low price, it’s competitive with top-tier modems. According to them, the Netgear CM500 “performed exceptionally well on a network that was stressed with simultaneous bandwidth-hogging software, including 3 large file downloads on a PS4 Pro, XBox One, PS4 Pro and 4K Netflix streaming.” Although it is best at speeds of 300 Mbps or less, the team tested 400 Mbps to ensure that there were no issues.
