Purchasing your own modem for Comcast Xfinity is a smart choice, but that does not mean that it is an easy choice. The first thing that you need to consider is whether the modem is included in the list of Comcast approved modems.
You need a Xfinity approved modem or you will not be able to get the most out of your internet services. You also need to take into consideration what you need from a modem and the type of use that you need for your household.
But how can you know what the best choice is? This is what you need to know.
Why To Get Your Own Comcast Approved Modem
If you are renting a modem from Comcast, the time has come for that to stop. Rental fees will add up quickly, and buying a new cable modem would save you money in the long run.
Comcast Xfinity charges $8 a month for modem rentals, but if you have Xfinity voice as well, there is another $8 modem rental fee, meaning you could be looking at $16 a month or $192 a year. If you are paying for that, you can certainly buy one of the modems compatible with Xfinity.
In addition, your own modem and/or Comcast compatible router will give you better control of your security and the ability to choose a modem with the speeds that you need for your home.
Modem vs Modem Router Combo For Comcast Xfinity
When it comes to buying a modem for Comcast Xfinity, you will get to choose between a modem and a modem router combo.
A modem uses a coax cable to connect the cable outlet to the modem, then an Ethernet cable from the modem to your computer. A modem by itself will not give you wireless internet, you will need a compatible router for that.
A Combo Is A Better Choice Than Just A Modem, Because:
- Only one box to plug in, fewer cords
- Cheaper to only have to purchase one modem
- Simpler set-up than separated router and modem
- Takes up less space

Step 1: Plug in the modem. This means to the power outlet as well as the cable port that is in your wall. You need a coax cable to plug it into the cable outlet.
Step 2: Connect one end of the Ethernet cable into the modem and the other into your computer.
