Comcast Xfinity Compatible Modems (2019 List)

Too often internet providers rope their subscribers into renting a modem from them directly, discouraging them to purchase their own.

Comcast Xfinity cable internet is no exception. They will happily rent you a modem for a monthly fee of $10, while you could be choosing from an array of Xfinity compatible modems for yourself.

The issue is that renting a modem is not only costly, but it is not going to get you all of the features that you might need from your modem. Their generic modems do not take into account your house size or even your network size, setting you up for lags in speed and overall frustrated users.

Do not worry, however. It is easy to get your own Comcast compatible modem, when you know what the benefits are.

Reasons To Get Your Own Xfinity Approved Modem

​Eliminate Rental Fees

There is no reason to pay rental fees to Comcast for a modem, when you can own one. Comcast charges $10 a month in rental fees, which quickly adds up to $120 a year. You can easily buy a modem for the same price and get all of the features that you want.

Better Performance

The modem that Comcast supplies might have all that you might think that you want from a modem. But really, you will have far better performance when you are able to choose your own modem. You can take into account what you do online and how many users are on your network at any given time.

Extended Coverage

The amount of coverage you need from your modem depends on your living space and the amount of devices that you have connected to it. ​Best modem router combos are built with the intention of having an extended network, having a range that can go through walls and reach every corner of your house.

  • Lower price tag: You will not have to pay for two separate units.
