Comcast XFINITY Approved Modems [Review 2022]

Comcast XFINITY has been in the market for a good time and is among the reputed companies when it comes to providing internet services. Comcast provides its own packages of internet along with a rented modem. Well, there might be a few benefits of using a rented modem provided by your internet provider, but there are a lot more benefits of using a modem that you purchase on your own. 

Using a comcast XFINITY approved modems can cost you around 8 dollars a month, and in case you also have Xfinity voice, then you have to pay another charge for the rented modem. So, overall using their rented modem can cost you around 16 dollars a month and 192 dollars a year.

So, if you are paying 192 dollars every year, then we guess that it will be better for you to spend an equal amount once and enjoy the rest of the coming few years without paying a penny for your modem.

People who understand this calculation and know the advantages of using your own modem instead of a rented one will definitely look for the options compatible with their internet providers. 

When it comes to Comcast, there are more benefits of using your own modem, such as you can customize the internet speed according to your package, you can also purchase a modem/router combo to avoid getting a separate router, you can enhance the stability of the connection, and do a lot of things that your modem allows you to do. 

In addition, a Comcast compatible modem will give you the finest performance if it is DOCSIS 3.1. Even though DOCSIS 3.0 can also work fine, it is somehow recommended to get the latest version. Plus, the speed and channels provided by the modem should be suitable with the Xfinity plan you are using currently. 

Well, apart from all these, the modem that you have to get for your use has to be Comcast approved, or else it will not work with it at all. So, you need to find modems that are approved to be used for Comcast and then look at the other factors.

Comcast-approved modems are numerous in numbers, and many brands give one of the best modems to use. So, to decide which will be suitable for you, the following are the factors on which you can rely and choose:

  • First comes a decision that needs to be made between buying a modem and a modem/router combo. Well, both have their own benefits, and you need both to run the entire system. However, it may be recommended to get both of them separately, but you can go for a combo if you have found the best for you. 
  • Next comes the obvious technology, which is DOCSIS. Well, DOCSIS 3.0. is also not bad, as it can also give you a high speed of up to 1 Gbps, while the 3.1 version can go up to 10 Gbps. So, depending upon your plan, you can get any. 
  • For Comcast, DOCSIS 3.1 is highly recommended as it is the latest one and can be future-proof as well in case you change your mind to enhance the plan. 
  • For DOCSIS 3.0 modems, you have to look at the channels as well. For Comcast XFINITY Approved Modems modems, the channel bonding should be between 8 x 4 and 32 x 8. 
  • So, in simple terms, the modem should have a downloading channel between 8 and 32 and an uploading channel between 4 and 8. Well, to state a fact, the more the channels, the more the speed will be. 
  • Next comes the speed of the modem and the speed of your internet plan. The speed also depends upon the channels and the DOCSIS version.
  • Well, to give you a brief idea of what speed of modem you should choose, the following is the table showing the channels and DOCSIS compatibility with the Xfinity plans:
Xfinity Internet PlanDOCSIS VersionChannels
Performance Starter Plus (50 Mbps)3.0 or 3.1At least 8×4 or more
Performance Select (100 Mbps)3.0 or 3.1At least 8×4 or more
Performance Pro (200 Mbps)3.0 or 3.1At least 8×4 or more
Blast! Pro (400 Mbps)3.0 or 3.1At least 8×4 or more
Extreme Pro (800 Mbps)3.0 or 3.132×8
Gigabit (1200 Mbps)3.1N/A
  • Since DOCSIS 3.1 does not use channels, you can get any. But for DOCSIS 3.0, the channel variation is given as per the internet plan you have. 
  • The type and number of ethernet ports are as important as any other factor. The latest ports can support 2500 Mbps of speed, while some standard ones can support only 940 Mbps of speed. So, if you’re looking for a wired connection, then this factor is more important.
  • Also, if you use Xfinity voice or you are planning to use it in the future, then you need to get a modem that supports Voice over Internet Protocol (VoIP).
