If you’re an internet customer of Comcast, you’re likely to have noted the monthly fee they pay on your modem rental bill.

Your cable modem–the device which takes the Internet signal from Comcast and makes it available to your home devices–is a small, important and efficient machine, but there is no need to lease it.

Yes, most cable modems pay in less than a year, making them an easy choice for both your home network and your wallet.

Whether you’re prepared to drop these fees or just upgrade your modem, check out our shopping guide to get an idea of what’s needed.

The Need for Speed: Docsis Demystified

Comcast has introduced its next-generation broadband distribution system in some areas of the U.S. providing households with internet speeds up to a gigabit which are greater than their comparable megabit level in several magnitude orders. It allows new technologies like 4 K video streaming and high-resolution audio to be built.

Nevertheless, you need a modem to support the right Data Over Cable Service Interface Specification (DOCSIS) rate to experience gigabit downloads.

For daily megabit internet, DOCSIS 3.0 modems are perfect. If you have only a few home users and you just don’t need cutting-edge speeds, a DOCSIS 3.0 modem is more than sufficient.

With gigabit Internet speeds, DOCSIS 3.1 modems are required and can accommodate multiple devices that access large amounts of data at the same time. Usually, DOCSIS 3.1 modems are compliant with DOCSIS 3.0 networks so that you can easily connect existing devices.

Wireless Routers in Modems

In addition to providing your home with internet service, most Comcast modems also include built-in wireless router features to provide Wi-Fi. These all-in-one solutions reduce the need for a separate wireless router capable of saving both money and counter or desk space.

In other words, most people use the following two criteria to buy a separate third-party Wi-Fi router.

Potential Wi-Fi upgrades: When you purchase a modem with an integrated wireless router and plan to update your Wi-Fi later on, you will end up having to buy a new wireless router. You can buy your own wireless router and update to your own timetable.

Security

If a security vulnerability warning arises (such as the 2017 WPA2 Wi-Fi password security flaw), it is up to the manufacturer of the wireless router to patch the problem. For wireless routers from third parties, you may hope to easily fix serious critical flaws.

By contrast, Comcast’s patch track record is poor, which means that you can remain subject to security threats for a long time.

Comcast certifies most cable modems from third parties, but its xFi services, including parental controls and network management systems, operate only on leased modems. Examine third-party implementations if you want access to xFi apps.
