Best Modem

While the top cable modem may not be something you consider often, it is one that should always be on your mind whenever you see your bill. You can save money by purchasing your cable modem and not paying a rental fee.

Although equipment rental charges may seem absurd, they are not a joke. Some ISPs charge as much as $14 a month when you use one of their modems, and that cost can add overtime. A cable modem that costs less than $70 is often the best, and you can pay your new modem off in half an year with a lower internet cost. The money that you pay to an internet service provider for renting an old modem will stay in your pocket.

How fast internet do you require? What internet speeds are sufficient? Here is a look at our tests to determine the best mesh Wi-Fi routers for greater home coverage. Whatever modem you decide to purchase, ensure it’s compatible and meets your requirements.

Which Cable Modem is the Best?

For most people, the best cable modem is the Motorola MB7420. It is compatible with most internet providers, such as Spectrum, Cox, Comcast, Cox, etc. and offers speeds that are the best for everyone (everyone with an internet service of at least 300 Mbps). Its two-year warranty is twice as long as the warranty for the Netgear CM500, which also performed reliably in our tests. Since the CM500 usually costs less than the MB7420, it’s a worthy alternative for bargain hunters.

Netgear’s CM600 provides faster internet speeds than 300 Mbps. It is reliable and more reliable than high-speed competitors.

The best Black Friday deals on cable modems rarely include modems, however that does not mean you won’t have to spend full price if your modem is purchased in the holidays. We have noticed price drops in many of these top cable modems, so shop around until you find the best deal.

Reasons To Avoid

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. (As of this writing, Best Buy is selling the SB6183.) 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. I find the coaxial cable connector a little close to the power connector. However, this will likely be an issue when you set up the modem.

The SB6183 favors a simple row of vertical indicator lights that are easy enough to spot, though the yellow lighting can be a little hard to see if your modem’s in direct sunlight. However, the SB6183 can be viewed to verify that your internet is working properly.

Best Cable Modem Vs. Best Router

These days, makers of home networking gear seem to favor modem-router combinations over standalone cable modems. The hybrid network devices are more versatile than separate routers and modems, so you could save money by buying one. But, modem/router combos are not recommended.

First, some background: as our modem-vs.-router comparison explains, the two devices serve very different purposes. An internet modem delivers internet connectivity to your house, while best routers connect it wirelessly so all your gadgets (phones, tablets, etc.) can access the Internet. A router is the best option if your current network doesn’t reach the extent you want.

It makes sense to keep these two devices apart. You can lose both your modem and router if any of the components in a mixed device fail. You can also upgrade your individual network devices more easily, since routers support newer networking features much faster. The number of available older models shows that modems develop more slowly.

What We Do to Test the Best Cable Modems

Comcast Performance Pro home internet service tests each modem. To ensure that the modems deliver the download speeds promised, speed tests are performed. We then use modems in regular networking setups to assess their dependability.

In order to test each modem, we hook it up at the home of the reviewer and use it in our network setup. That allows us to verify a modem’s compatibility as well as to get a sense of its dependability. We also track retail websites for the lowest prices on modems that we have tested.

(Image credit Tom’s Book) To ensure that the indicators lights are clearly visible on the modems we use them in our home, which includes multiple tablets, phones, and computers. It is important to consider how simple the modems can be set up. Because the main reason you want to own a cable modem to cut down on ISP monthly rental fees, we weight the modem warranty’s length heavily.

Our Selection

Motorola MB7621 – The modem that’s best for you. Compatible with almost all internet service providers, the MB7621 is compatible with 600 Mbps plans. It’s widely supported, it has a two-year warranty, and it pays for itself in about eight months.

Amazon $90 – Walmart $90 – Best Buy $80 – $90

Motorola MB7621 has the highest internet speeds and is highly reliable. 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. A two-year warranty is included.


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. A DOCSIS 3.1 router is required to ensure gigabit connections from all cable internet providers. Additionally, the Motorola MB8600 supports gigabit internet through networks still using the DOCSIS3.0 standard. Sparklight/Cable One for instance allows you to use both DOCSIS 3.1 and DOCSIS3.0 modems in 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. If they start gigabit service, they might not allow you to bring your modem.

How many Mbps are you able to use?

Mbps, or megabits per second, are just about the most important factor in deciding what modem to get, as the number can make or break great internet service. You will get faster and better internet service if your Mbps is higher. Modems can have anywhere from 10-1,000 Mbps, and the more megabits you have, the more traffic (or greater bandwidth) your modem can handle. You will be able to determine the number of Mbps that your modem requires based on who you are and what your use it for.

Video games, streaming videos and large files take 5-10 Mbps. Downloading larger files takes up to 50Mbps. You should stick to a minimum 50Mbps speed modem. However, the majority of modems will handle enough to power multiple users and a heavy router.

Most modems will also have Data Over Cable Service Interface Specification or DOCSIS technology. It is the preferred standard for cable companies because it saves energy and speeds up connections. 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 V7100V

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

Voice control makes just about everything better. However, it would be hard to beat the Nighthawk C7100 if this feature wasn’t available. 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. This modem is not required for speed now. However, it has a maximum of 960Mbps which will make your life easier and prevent you from needing to purchase a new modem. Although this Nighthawk may have the drawback of being dual modem/router, its unique feature includes two phones that are compatible with 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. However, when you can find one, it’s one of the best available for such a low cost. It is small and lightweight, with bright lights that are easy to see.

Tom’s Guide praised the two-year warranty (which is longer than most policies you’ll find on a modem) and the speeds of up to 686 Mbps features that punch well above the Surfboard’s price range.

Netgear Cm500

Consumer Score: It was rated 4 out of 5 by 98%. This score is a great deal considering the price and its elegant, simple design.

We don’t think your modem should be considered a work of art. However, we are concerned about it being an eyesore. This particular model has a sleek and sophisticated look, though the shiny exterior can easily smudge. Unfortunately, it doesn’t have great ventilation. Keep your CM500 in a cool place to prevent heat buildup. Top Ten Reviews said that the CM500 is competitively priced with higher-quality modems despite it being a low-cost model. They wrote that the Netgear CM500 did exceptionally well in a network with four bandwidth-hogging apps, which included three big game files on a PC and XBox One and also 4K Netflix streaming and PS4 Pro. While it’s best running at only 300 Mbps or lower, they tested up to 400 Mbps and didn’t have issues.

CenturyLink Certified Modems Router FAQs

Understanding modem compatibility Each modem is designed for a particular type of internet technology, and at a given speed. CenturyLink can use different core technologies such as fiber or DSL, depending on where you live and how fast your internet speed is.

It is important to understand why this matters. You can’t use CenturyLink modems unless they are compatible with your particular technology and speed.

The Reasons We Choose Our Favorite Cable Modems

We looked into eight of the most popular modems and then narrowed it down to five based on the following criteria:

Supported speeds

Price and value


Customer reviews

Supported speeds and value are two of our priorities. Because customers will have different preferences based upon their internet speed plans and financial resources, we offer many choices rather than only choosing the top five modems.

We consider each modem the best in at least one of five major categories. These include best value overall and easiest setup, streaming and gaming, gigabit internet plans, and budget-friendly. These are the Arris surfing board SB6183, Motorola MB7420 and Motorola MB7621. We also like the Netgear CM500.
