Unlike DSL and dial-up connections, cable modems provide fast internet as standalone devices. They allow your computer to communicate with your ISP to provide fast broadband solutions. As such, you’ll enjoy lag-free gaming and streaming of videos.

Cable modems also eliminate the need to pay rental fees on additional equipment, so not only can they support high-speed internet, they can also save you money in the long run. And, paired with a Wi-Fi extender or two, there's no need for an elaborate, expensive mesh Wi-Fi system.

Here are the best cable modems available today.

FAQ

Q: Are Cable Modems Repairable?

Fortunately, troubleshooting some problems in cable modems is easy, even without technical knowledge or tools.

First, make sure the connections are tight since loose-fitting cables may disrupt your network. Sometimes restarting your computer eliminates bugs that may interfere with your home internet.

Another handy way to fix sudden malfunctions is wiping off dust since a build-up on the internal components causes overheating. You can also buy a Coax cable tester to check if you’re receiving a valid signal from your ISP.

Q: Are Cable Modems Long-Lasting?

How long your cable modem lasts depends on the build quality. High-end cable modems can serve you for over five years and budget-level ones between two and three years.

Most devices that last for several years use premium capacitors and are well-ventilated to prevent overheating.

In addition, you can increase your cable modem lifespan by cleaning it once in a while. It’s a great way to prevent dirt build-up that may interfere with normal operations.

Q: What Key Factors Should I Consider When Shopping for a Cable Modem?

The most critical factor is ISP compatibility as you don’t want a cable modem that doesn’t work with your current service provider. You can find out by checking the listings on your preferred device.

The DOCSIS protocol also affects your buying decision. One with the latest (currently DOCSIS 3.1) allows you to experience super-fast speeds, even in the future.

Other factors include the number of channels, ports, build quality, size, and security standards.
