Best cable modem 2023

Buying your own Internet modem isn’t just a great way to avoid paying rent from your ISP—by choosing a better model than what your cable company offers, you can unlock better Internet and network performance. And if you’re paying for super-fast Internet speeds, running one of the best cable modems can unlock the performance you’d otherwise waste with a slower model.

Of course, you don’t have to buy the most expensive model. Some (like our favorite, the Motorola MG7700) double as a router and come with dual-band Wi-Fi 5 built in, which is probably all the networking hardware you’ll ever need. Alternatively, for those looking for a cheap and cheerful modem to get out of your ISP rental package, the Netgear CM500 is a very smart and popular choice.

No matter what kind of modem you need, however, this list has something for you. Here are some of the best cable modems you can buy today.

The Motorola MG7700 is one of the most popular third-party modems you can buy, thanks to its combination of excellent features, the ability to act as both a modem and a router to simplify your Internet connection, and its relatively affordable price. While most modern modems tout their ability to support Gigabit+ internet speeds, it’s not something everyone has access to, and there’s no reason you should pay for a feature you can’t use. However, that doesn’t mean the MG7700 is slow. It can support Internet speeds up to 800 Mbps and has four Gigabit Ethernet ports for fast network data transfers and no Internet bottlenecks.

It also has built-in Wi-Fi 5 support, which again isn’t the fastest standard, but it’s more than fast enough for everyday web browsing and video streaming. It is supported by most major ISPs and has useful extra router features such as parental controls and guest network support. You can always add your own router later if you want to improve Wi-Fi performance or coverage, but for most Internet users, the Motorola MG7700 offers everything you’ll need for the foreseeable future.
