How to choose the best cable modem

When choosing the best cable modem, you should consider the following characteristics:

Supported speed

Higher download/upload speed is always a better option. However, the fastest devices usually demand the most money and many people simply aren’t capable of paying that much.

Therefore, try to find the best ratio of speed and price and don’t forget to look a bit more into the future, and try to predict what will be your speed requirements, in a few years and in accordance with that, choose a device that will also be future-proof.

DOCSIS

DOCSIS (Data Over Cable Services Interface Specification) is a telecommunication standard that tells you what your cable modem capabilities are and suggests what its maximum download and upload data transfer speeds are.

In theory, DOCSIS 3.0 should provide a maximum download speed of 1200Mbps and maximum upload speed of 200Mbps, while DOCSIS 3.1 should provide up to 10Gbps download and 1Gps upload speeds.

In other words, choose the device with the standard that supports your demanded speeds and try to fully benefit from every advantage that certain standard brings along.

Certification

Although it may not sound as important as speed, or DOCSIS functionality, the fact is that a lack of proper certification will make the cable modem not worth a dime. If your chosen device isn’t supported by the major cable providers, it is worthless. Even the best cable modems out there will have no purpose, if it can’t be used with Cox, Spectrum, Xfinity, and other operators.
