The Best Cable Modems of 2023

Jun 25, 2023Jun 25, 2023

Save on monthly fees by investing in a cable modem that's supported by your ISP.

With many Internet Service Providers (ISP) charging monthly fees, you can save money within the first year by investing in a new cable modem and improve your internet speeds with the right one.

Choosing a new cable modem isn't as simple as grabbing any random modem off a shelf. It requires some research to ensure you are choosing the right one to work with your ISP and ensuring it has features that will benefit you.

If you're unsure if a cable modem will work with your internet provider, most ISPs can offer you a list of approved modems. Simply provide them with our list of recommended cable modems, and they will let you know which ones will work with their service.

In addition to saving you money each month, buying your own cable modem can also offer impressive benefits, including improved features, more ports, more channels, and improved maximum download and upload speeds.

If your ISP offers multi-gig connectivity, you might want to consider choosing a cable modem supporting DOCSIS 3.1. Not only will these cable modems offer much higher speeds, but they also offer a more reliable connection, making them a worthwhile investment.

Depending on your needs, you might also contemplate a modem-router combo. This will save you space in your home and be more cost-effective. As the router and modem are connected, they are designed to work together harmoniously, often resulting in improved performance. Having a combo also makes setup and managing your network much easier, as everything is controlled from one device.

✓ DOCSIS 3.1

✗ Expensive

✓ Multi-gig speeds

✗ Only one Ethernet port

✓ Xfinity support

✓ Multiple ISP support

Motorola is well known for making some of the best cable modems on the market, and the Motorola MB8611 is one of its best, offering premium features, albeit at a premium price.

As long as you have an internet plan capable of reaching these speeds, the Motorola MB8611 can hit up to 2.5 Gbps. It also comes with a 2.5 Gbps Ethernet port, although considering the high price, more than one Ethernet port would have been ideal.

The Motorola MB8611 offers premium features such as DOCSIS 3.1, IPv6, and Active Queue Management (AQM), offering higher speeds, reduced ping, and much better latency. While these features might be overkill for some, they are perfect for gamers, streamers, or busy households using a lot of bandwidth.

While the Motorola MB8611 might be a little more expensive than your average cable modem, it offers future-proof connectivity and features, so you won't need to worry about upgrading your cable modem for years to come.

This DOCSIS 3.1 cable modem supports speeds up to 2.5Gbps and features AQM for lower latency.



✓ DOCSIS 3.0

✗ Maximum speed of 686 Mbps

✓ Excellent value for money

✗ Only one Ethernet port

✓ Easy to set up

If you're on a budget but need a cable modem, the ARRIS SURFboard SB6183 is an affordable choice. With DOCSIS 3.0 technology, it can support maximum download speeds of up to 1Gbps—unlike DOCSIS 3.1, which can support up to 10Gbps.

For smaller homes or users who don't do a lot of gaming or streaming, the ARRIS SURFboard SB6183 is a great starting point. It's pretty basic, and as it's not a combined modem/router, you won't be able to connect to Wi-Fi solely with this unit. Still, it supports most major US cable ISPs like COX, Spectrum, Xfinity, etc.

With support for any Wi-Fi router or mesh system, the ARRIS SURFboard SB6183 has two Gigabit Ethernet ports. If you don't need Wi-Fi immediately, you could simply use the cable modem as long as it's plugged straight into your device.

Setup is pain-free—download the SURFboard Central app and follow the on-screen instructions to activate the modem to connect to a Wi-Fi router. However, if you want to get set up straight away with a cable modem and mesh system, there is the option to upgrade to the DOCSIS 3.0 Modem + AC3800 Mesh System. This, of course, does come at an extra cost.

If your home internet speeds are limited to around 300Mbps, the ARRIS SURFboard SB6183 will help you get connected at a budget-friendly price. It may not be packed with features or offer immediate Wi-Fi access, but some users may not need the extra frills.

A cheaper alternative to most cable modems, this DOCSIS 3.0 modem is a great starting point for those on a budget.



✓ DOCSIS 3.1

✗ Expensive

✓ QoS support

✓ Two Gigabit Ethernet ports

✓ Built-in OFDM/OFDMA support

Netgear is known for its solid and reliable routers, but it also offers efficient modems like the Netgear Nighthawk CM1100. This cable modem supports speeds of up to 10Gbps, thanks to its DOCSIS 3.1 technology. It also has two Gigabit Ethernet ports, two OFDM downstream, and two OFDM upstream channels.

If you plan on using a wireless network, the Netgear Nighthawk CM1100 also supports most mesh and Wi-Fi routers. Even if not, though, this cable modem is a beast if you're happy to stick to wired connectivity. If your ISP can provide two IP addresses, you can make use of the modem's multi-Gig speeds. And, if you do get a wireless AC or AX router, the Nighthawk CM1100 supports QoS support so you can prioritize traffic on select devices.

While it does boast built-in support for OFDM/OFDMA channels, the native setup of the Netgear Nighthawk CM1100 should be sufficient. With minimal lag, you can pick up your laptop for streaming or game on your PC. It also supports IPv6, which is useful for advanced users.

Pairing the Netgear Nighthawk CM1100 with a suitable Wi-Fi router like the Netgear Nighthawk RAX120 will net you decent speeds, so if you're in a family home and want to connect multiple devices to your home's network, the CM1100 makes the process easy.

Boasting a stylish design, DOCSIS 3.1 technology, and IPv6 support, this cable modem is a worthy investment if you want access to faster speeds.



✓ 2.5Gbps Ethernet port

✗ Only one 2.5Gbps Ethernet port

✓ 32x8 channel bonding

✓ Easy setup

If gaming is your jam, the Netgear Nighthawk CM2000 is worth considering. It is suitable for plans up to 2.5Gbps and comes equipped with DOCSIS 3.1. This cable modem is also compatible with all major cable internet providers like Xfinity, COX, and Spectrum.

The Netgear Nighthawk CM2000 has one Ethernet port, but when paired with a Wi-Fi router, this cable modem can reach some high speeds, perfect for PC and console gaming. And, with a mesh system, you can get superfast Wi-Fi across your home.

Setting up the Netgear Nighthawk CM2000 is easy, too. Connect your coax cable to the modem and an Ethernet cable to your device. Here you can follow the on-screen setup. Opting for a cable modem will eliminate monthly rental fees and get direct access to your home's network.

If your cable provider only allocates one IP address, the Netgear Nighthawk CM2000 is perfect for your needs. But, if you need more Gigabit ports and want to forego some speed, you could drop to the Netgear Nighthawk CM1100. Still, if you're gaming on one device at a time, the CM2000 will give you that much-needed upgrade.

Don't want to set your cable modem up on your device? You can call your cable modem provider to activate the Netgear Nighthawk CM2000 over the phone. If you run into any trouble, Netgear provides great tech support—they really know what they're talking about.

Suitable for cable plans up to 2.5Gbps, the Netgear Nighthawk CM2000 is the perfect companion to have for larger homes or game-focused devices.



✓ Stylish design

✗ Very lightweight so is prone to tipping over

✓ DOCSIS 3.1

✓ Reasonably affordable

✓ 2.5Gbps and Gigabit Ethernet ports

Stylish cable modems can be pretty hard to come by. But, if the design of your modem is important to you, then the ARRIS Surfboard S33 sets the bar quite high. This cable modem can handle speeds up to 2.5Gbps and two static IP addresses.

If your internet speeds are slower than 300Mbps, it's probably worth investing in an alternative SURFboard modem, like the ARRIS SURFboard SB6183. Spending unnecessary money on a DOCSIS 3.1 modem isn't a wise move for sub-Gigabit connections. But, if your speeds are higher, this is an excellent future-proof investment.

Price is also an important factor; the ARRIS Surfboard S33 is a cheaper alternative to the Netgear Nighthawk CM2000, but will offer similar speeds. Similar to other ARRIS cable modems, this one has a web user interface that you can easily access or download the ARRIS SURFboard Manager app. You won't need either for activation with an Xfinity cable plan, making the process super simple.

In addition to your purchase, the ARRIS Surfboard S33 comes with a power supply, a quick-start guide, and a two-year warranty. It's a little more expensive than a DOCSIS 3.0 cable modem but at the lower end of the price spectrum for DOCSIS 3.1 modems.

With a 2.5 Gigabit Ethernet port and 1 Gigabit Ethernet port, the ARRIS Surfboard S33 is a solid option if you enjoy streaming TV shows and movies, YouTube videos, or games on your laptop or game console. It won't break the bank, but it will forge the way to higher internet speeds and access to a Wi-Fi 6 connection.

Future-proof your home network by investing in the ARRIS SURFboard S33 and get access to DOCSIS 3.1 at an affordable price.
