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. By purchasing your own cable modem, instead of renting equipment from your provider’s drop-off location, you will save money on internet services.

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. Cable modems that cost less than $70 are usually the most affordable. You will be paying off your modem costs with lower monthly internet bills in about half a year. This means that the money you’d have to pay your internet provider in order to rent an older modem is yours to keep.

What internet speed do you need ? What internet speeds are sufficient? Here is a look at our tests to determine the best mesh Wi-Fi routers for greater home coverage. No matter which one you end buying, just make sure you’re getting a modem that’s compatible with your ISP and pick a device that delivers speeds in line with your service plan.

Which Cable Modem is the Best?

The Motorola MB7420 is considered the most reliable cable modem. It works with a wide variety of internet providers, including Comcast, Spectrum and Cox, and it delivers speeds that will serve the greatest number of people (anyone whose internet plan tops out at 300 Mbps). Two-year warranties are twice the length of those for Netgear’s CM500. They also perform well in our tests. It’s a great alternative for bargain-hunters, as it typically costs less than the MB7420.

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

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’ve noticed price drops on many of the best cable modems on this list so be sure to shop around for the best price.

What 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.) A two-year warranty, which is available at a very competitive price for the SB6183, can also be a huge plus.

The white SB6183 measure 5.2 x 5x 2.1 inches. This makes it easy to conceal next to the router, cable box or any other hardware. 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.

It features a small row of horizontal indicator lights. This makes it easy for users to find the SB6183. But, direct sunlight can make it difficult to see the yellow light. You can still glance at the SB6183 to determine if there is an issue with your internet connectivity.

Best Cable Modem Vs. Best Router

Today, modem-router combination seem more popular than standalone cables modems. These hybrid devices can be more appealing than a standalone modem or router. You can accomplish two tasks using one device. But, modem/router combos are not recommended.

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. The router you need to improve the network reach is what you should be looking for.

Why keep them separate? A failure of any component in a hybrid device will result in both the loss of a modem or a router. You can also upgrade your individual network devices more easily, since routers support newer networking features much faster. As you can see, modems are slower to evolve.

Our Test of the Top Cable Modems

Comcast Performance Pro Home Internet Service tests every modem. Once we have run speed tests to verify that modems can deliver their download speeds, our regular networking setup uses the modems to test reliability.

We hook up each modem we review in our reviewer’s home, using it as part of our networking setup. We can verify the modem’s compatibility with our network setup and get an idea of its dependability. Because modem prices are an important aspect of modem shopping, our team monitors retail sites looking for the best deal on the modems they’ve tested.

Image credit to Tom’s guide. We use modems to connect multiple devices, including tablets and smartphones, to test their visibility. It is important to consider how simple the modems can be set up. Since the principal reason for purchasing a cablemodem is to avoid monthly rental fees from ISPs, we place a lot of importance on the length and duration of a modem’s warranty.

If your internet provider allows you to use your modem with gigabit speeds, then the Motorola MB8600 may be the best DOCSIS 3.1 routers available. For gigabit Internet speeds, you’ll need a DOCSIS 3.1modem. However, most cable ISPs will only allow the MB8600 to work with gigabit networks that use the DOCSIS3.0 standard. Sparklight/Cable One is compatible with both DOCSIS3.0 (32×8) as well as DOCSIS 3.1 modems when it offers its GigaOne services.

If you do not have gigabit Internet service or already know that it is available, don’t buy a gigabit modem. 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 Do You Need?

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. The higher it is, the better and faster your internet will be. The modem can support up to 101,000 Mbps. If you have more megabits, your modem will be able to handle more traffic. How many Mbps you need will depend on how many people are in your house and the purpose of your internet use.

While streaming video and games take between 5-10Mbps while large file downloads can take as much as 50Mbps. In general, you’ll want to stick with at least a 50 Mbps modem. You can still use the modem to run multiple concurrent users, a heavy-duty router or multiple computers.

Most modems have Data Over Cable Service Interface Specification. It is the preferred standard for cable companies because it saves energy and speeds up connections. The most current version of DOCSIS 3.1 is available, however, DOCSIS 3.0 can be used for 100 mbps speeds. There are many ways to get internet through your ISP. However, DOCSIS is the most reliable and should suffice for most users.

Netgear Nighthawk C7100V

Consumer Score: 82% gave this product 4 stars and higher.

Voice control makes just about everything better. Although it doesn’t come with this handy feature, Nighthawk C7100 still ranks high among router-modem combos. While it is certainly pricey, you get incredible speed in an easy-to-use package. This modem can reach speeds of up to 996 Mbps and is a great investment for the future. 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. Although this Nighthawk may have the drawback of being dual modem/router, its unique feature includes two phones that are compatible with Comcast. This means the device will only work with Xfinity.

Arris Surfboard SB6183: Consumer Score 84% gave it 4 Stars or More. Compact, simple modem that is affordable.

Surfboards have a long history of being affordable and a well-respected choice. However, when you can find one, it’s one of the best available for such a low cost. The device is very compact and has bright and easily readable lights.

Tom’s Guide praises the Surfboard’s warranty of two years (which is significantly longer than other policies) as well as the Surfboard’s speedy speeds up to 686Mbps, both features which were very competitive with the Surfboard’s prices.

Netgear Cm500

Consumer Score: 98% gave it 4 stars or more Score speeds way above its price point and a simple, elegant look.

We don’t think your modem should be considered a work of art. However, we are concerned about it being an eyesore. The exterior of this model is sleek and elegant, but it can easily get smudged. 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. “[The] Netgear CM500 performed extremely well on a network stressed by running four simultaneous bandwidth-hogging applications, including three large game file downloads on a PC, XBox One, and PS4 Pro and 4K Netflix streaming,” they wrote. While it’s best running at only 300 Mbps or lower, they tested up to 400 Mbps and didn’t have issues.
