Linksys recognizes that a modem isn't supposed to be a centerpiece, and so it makes sense that the design of their CM3008 is designed to work reliably while staying out of your way. The compact design makes it an ideal option for more crowded homes and offices, but they fit everything most users could conceivably need into that small frame.

Its curved, futuristic design will really help it stand out in your home, office, or home office without being ostentatious about it. And while you shouldn't buy a new modem based off looks alone, there are a lot of characteristics to like about this reliable cable modem.

This cable modem is compliant with DOCSIS 3.0 protocol, which doesn't put it among the faster speeds on our list but still puts it in a respectable space. And the LED indicator lights are expressive and simple to understand. But if you have a trouble with your internet access, you don't necessarily need to get customer service on the phone.

Cable Modem Buyer’s Guide

If you’re looking for the best cable modem, you don’t have to rely solely on a reviewer. Our guide breaks down the fundamentals to look for when shopping for you can expand your reach further. We’ll cover the most important specs and answer some of the questions we hear most frequently from our readers.

Manufacturer

Is the company behind your cable modem a big deal? If you don’t plan on doing much research, it can be. Top tier names like Arris, Motorola, and D-Link have built a reputation for making some of the best cable modems around, while younger manufacturers like Zoom Telephonics have really earned a name for themselves in recent years for the quality of their cable modem designs.

If you pick a modem produced by any of these names, you can be relatively assured that you’re getting a quality product, and that’s fine if you just want to replace your existing modem or move away from renting one from your ISP. And the simple fact is, most users won’t notice much of a difference between the different modems listed. But if you’re really serious about getting the most out of your plans or shopping for your workplace, you’ll want to dive deeper than just name recognition.

Ethernet Ports

If you don’t plan on buying a dedicated router and aren’t looking at combo routers with modems built in, the number of ethernet ports available are going to be incredibly important. The ports available determine how many devices you can connect to the internet, and a modem with few ports can be a huge liability in that case.

That said, we almost universally recommend investing in a router. If you have a normal online DSL connection at your home or office, a single port connected to a router will work just fine. Serious gamers or those who want their streaming interrupted can benefit from a modem with extra ports though. Connecting a device directly to the modem rather than connecting it on Wi-Fi results in a faster and more reliable online experience for that device, allowing you to prioritize the consoles, computers, or other products that you use most. But unless you have specialized needs, just stick with a single port modem and a router.

Other Ports

While ethernet ports and the cable port for your modem are going to be the most important outlets to look for when shopping for a modem, some models (particularly modem/router combos and those tailored towards business consumers) come with some additional features as well. The most popular is a VoIP (voice over IP) port. These allow you to make calls from a designated land line without needing a traditional phone plan. Since it’s using the internet instead of a traditional phone line, you don’t need to pay for a separate phone plan, and you can rely on the quality of your modem to get the job done.

You may also find a cable modem with USB ports. These are far more situational but can be useful in office environments. These are most often used to connect a hard drive or a thumb drive to your modem so that you can readily share information to the whole network, but they can also be used to more easily add a printer, scanner, or fax machine to your high-speed internet network.

Download and Upload Speeds

Cable modems have come a long way in terms of how well they can perform. The original dial-up modems were capable of downloading 56 kilobits a second. The best cable modems you’ll find offer a download speed of a gigabit a second, which is the equivalent to 1,000,000 kilobits. Even the most basic entry level modems will provide you with 100 Mbps, and most offer 300 Mbps or more. In other words, the download speeds of 30 years ago are a tiny fraction of what the most basic modem cable can accomplish today.

So how much power do you need? Considering that the average ISP plan offers a rate of 150 Mbps, you can be confident with practically any modem you’ll find here, but if you’re more of a power user, you’ll want to make sure that the maximum supported download speed your modem lists as at least as high as the standards for your provider. Better internet speeds will ensure better streaming and quicker downloads, and getting a modem that can outperform your plan means that you’ll be ready to go if you do decide to upgrade your plans in the near future for faster performance.

That said, just because plans give you a maximum download speed doesn’t mean that you can expect that speed from every device in your network. Devices connected to a Wi-Fi network will typically not offer the same speed as wired connections, and the speeds for each device will be lowered since that bandwidth is being shared across your entire house or office. That’s why it’s important to consider not just the maximum bandwidth you’ll use on any device but the maximum bandwidth you can expect your household to use concurrently when shopping for internet plans and modems.

If you’re looking to determine what speeds you can expect from your modem at a glance, you may want to check what DOCSIS 3.0 cable protocol is supported. DOCSIS 3.0 typically supports speeds of a little over 300 Mbps, while a DOCSIS 3.1 modem will offer a full gigabit download speed at max. Upload speeds are going to be far less important for most users, but they’re still worthy of consideration. In almost every case, the upload speed is going to clock in at about a third of the download speed.

Modem and Router Combinations

Are you fine with a plain modem, or do you need a wireless router/modem combo? The latter certainly comes with conveniences. It allows you to save space by not making use of two separate devices, and you know that you’ll be getting the best out of both the router and modem because they’re built from the same hardware. If you want Gigabit internet for online gaming, you need both a Gigabit router and an equivalent modem. A combination helps you avoid that issue.

That said, if you already have a router that you’re happy with, you should be able to find a close modem that works well for a fraction of the price.

Compatibility With Your ISP

Just because a modem has the speed, features, and functionality that you need doesn’t mean that it’s going to work with your service provider. Any ISP is going to have a list of modems that work for their network, and most manufacturers list the internet service providers and plans they’ve been certified through. If the model you find has been certified for your provider and plan, you should be good to go and be able to get the most out of your modem.

But if your favorite model hasn’t been officially listed, you may not be out of luck. That’s especially true if you’re working with a smaller provider that doesn’t have as much visibility. Certification requires a provider to test each modem manually. There are way too many models on the market to make testing them all feasible, but most should be built to the specifications of a provider. If you’re unsure, be sure to check out reviews and specs for the modem. Even if it’s not officially approved, it may still work. Just be sure to look carefully at reviews, as you may not get the peak performance you’re hoping to find from your modem. Other users can provide you with a deeper analysis.

IP Address Protocol

Whether you’re looking to upload or download data, any device connected to the internet over a Wi-Fi or physical connection is assigned an IP address. This allows it to have its own unique identity and communicate clearly with other servers and devices that make up the larger structure of the internet. The initial protocol used when internet technology was first developed is known as IPv4, and while it works just fine, there’s one major problem – we’re slowly running out of available IP addresses.

That’s where IPv6 comes in. It allows for more IP addresses to be used, and while that’s a big deal for the future of the internet, it won’t matter much to the average consumer. If you plan on having your modem for years and years to come, getting a cable modem that supports IPv6 protocol might be a smart idea, but it won’t make much of a difference to most users.

Customer Service

A failing modem can cut your off from your internet connection, so if you’re not technically inclined, you may want a model that offers customer support. Many models offer a one-year warranty or two-year warranty with purchase.

Frequently Asked Questions

What is the Best Cable Modem to Buy?

We love the Motorola MB8600. While it’s certainly not the cheapest modem around, it’s easily one of the most reliable. It offers incredibly fast download speeds thanks to the channel bonding built in and the inclusion of DOCSIS 3.1 protocol. And not only is it exceedingly quicker than the traditional 300 Mbps download speed modem, but it also offers pretty strong security features.

What is the Best Modem for Xfinity?

That’s a hard question to answer. While the Netgear CM500 is built to handle all the major Xfinity plans, the right choice really depends on your plan, the service in your area, and your personal needs. As long as your model is certified to work with Comcast Xfinity, you can rest easy knowing that it will work to the standards established in its description.

Is it Better to Buy Your Own Modem?

Absolutely. The best cable modem may be more expensive to buy than a month’s modem rent, but it will pay you back dividends sooner rather than later. It’s estimated that it can cost between 120 and 160 dollars to rent a modem, so even the most expensive models should save you money in less than two years. And the fact that you can pick a model that’s more suited to your needs is well worth the upfront cost for most customers.

Should I Upgrade My Cable Modem?

That really comes down to how well your current modem is working. If you currently rent, we highly suggest buying a new modem. Otherwise, check the terms of your existing plan, and then test out the speeds you’re getting from your modem using a free tool like the one that can be found at Speedtest.net.
