You probably don’t think about the best cable router very often but you need to keep it in your thoughts the next time your internet bill comes. If you buy your own cable modem instead of using whatever device your internet service provider dropped off, you can probably save money on your internet service by eliminating a needless equipment rental fee.

The equipment rental fee is not only ridiculous but also very serious. You could be charged $14 per month by ISPs to use their modems. And that can increase 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.

What speed internet connection 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.

What is the best cable modem?

Motorola MB7420, for the majority of people is the


“>best modem. It can be used with multiple internet providers such as Spectrum, Cox, Comcast and Cox. The fastest speed available is 300 Mbps. Its 2-year warranty outlasts the Netgear CMS500’s warranty. However, it performed as expected 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.

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. Many of our top-rated cable modems have seen price drops, so make sure you shop around to find the lowest price.

Here are some 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. Best Buy currently sells the SB6183. You can find the SB6183 on sale at a great price.

All-white SB6183 is small at 5.2 x 5. x 2.21 inches. It can be placed next to your router, cable box, or other hardware that you may have. 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 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. The SB6183 is easy enough to check if you have any issues with 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, some history: The modem and router have different uses. Cable modems provide internet connectivity in your home, while routers wirelessly distribute the internet connection to all of your smart-home devices, including phones and tablets. 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. Failure of any one component of a hybrid router or modem will cause the other to fail. Upgrades of individual networking devices are easier because routers allow for more advanced features. As you can see, modems are slower to evolve.

What We Do to Test the Best Cable Modems

We test each cable modem on Comcast’s Performance Pro home internet service. After running speed tests to make sure the modems are delivering their promised download speeds, we use the modems as part of regular networking setup to gauge dependability.

Every modem we test is hooked up in the reviewer’s house. We then use it to set up our network. It allows us both to check a modem’s compatibility, and also to assess its reliability. We also track retail websites for the lowest prices on modems that we have tested.

Image credit to Tom’s guide. We use modems to connect multiple devices, including tablets and smartphones, to test their visibility. We evaluate how easy modems are set-up. And because the primary reason to get your own cable modem is to save on monthly rental fees for ISP-supplied modems, we heavily weight the length of a modem’s warranty.

Our Pick

Motorola MB7621 The most popular modem Compatible with many ISPs, this modem supports 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 from Walmart $80 From Best Buy

Motorola MB7621 provides reliable internet access and supports fast internet speeds for the majority of Americans. The Motorola MB7621 also works with nearly every other non-gigabit cable plan in America, including Spectrum, Cox, Suddenlink and Sparklight/Cable One. This allows you to move ISPs or change them. Because it is a DOCSIS3.0 modem, the MB7621 can support plans of up to 600 megabits each second. It also has 24 downstream channels as well as eight upstream channels. A two-year warranty is included.


Budget Pick

NetgearCM500 Plans up to 300Mbps This former top pick remains a great choice, as long as your service plans are not faster than 300Mbps.

Walmart $46*, Amazon $43 Amazon Best Buy

America has an average internet speed of 180 Mbps. This depends on which survey you select. The Netgear CM500 is recommended if your plan falls within this range, and you do not intend to increase the speed of your internet connection beyond 300 Mbps. Although it has ISP compatibility comparable to the pricier CM600, the CM500’s maximum download speed is 300 Mbps and the CM600 600 Mbps, although Suddenlink certifies it at 500 Mbps speeds. Although the CM500 is known for its reliability, it only comes with a 1-year warranty.

We recommend the CM500 16×4 modems, even if you have a plan that would use a slower modem. 8×4 modems are being dropped by ISPs. This will save little money upfront, but you’ll have to buy a new modem many years before.

There are many buying options

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

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.

Don’t get a gigabit modem unless you already have gigabit service or know it’s available. The extra expense for DOCSIS 3.1 modms may not be worth it unless you are on one these costly plans. And they may not even let you bring your own modem once they do roll out gigabit service.

How much Mbps will you really need?

The most crucial factor when choosing a modem is Mbps. It can be a huge factor that makes or breaks great internet service. You will get faster and better internet service if your Mbps is higher. Modems have speeds of between 10 to 1,000 Mbps. The higher the megabits available, the greater the traffic or bandwidth your modem is able handle. Your modem will need to support the following:

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. However, DOCSIS 3.1 has been the most popular. However, DOCSIS 3.2 works for speeds of up to 100 mbps. 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% given it 4 stars or greater. The two-in-1 has voice control and phone lines.

Voice control can improve almost any situation. Even without this feature, Nighthawk C7100 could easily be ranked at the top of router-modem combinations. Although it’s expensive, the package offers incredible speed and is easy to use. 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. The Nighthawk’s disadvantage is that it can only be used as a dual router modem, but it has two lines of phone service included with it. This means the device will only work with 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. The Surfboard can be found for as low as $199, so it is a good option. This modem is lightweight and bright, making it easy to use.

Tom’s Guide was impressed by the Surfboard’s two-year warranty, which is more than any other modem policy. Also noted were the Surfboard’s high speeds (up to 686Mbps), that are well worth the 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.

Your modem shouldn’t be considered an object of art. But many are worried that it could become 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. It’s recommended to run at 300 Mbps, but they also tested it up to 400Mbps without any issues.
