Because outdated equipment and firmware can slow down what would otherwise be a fast connection, you'll want to make sure your network setup is always up-to-date to get the most out of your Xfinity Internet service.

Like computers and mobile devices, new WiFi equipment models are released regularly. While you don't need to immediately update your equipment to keep your home network running, you could be missing out on improved services if you continue to use older models.

Upgrade Your Owned Modem

If you want to enjoy our faster internet speeds, such as Blast!, a DOCSIS 3.0 or above modem is required. You can rent one of our DOCSIS 3.0 Xfinity xFi Gateways, or you can buy an approved modem at a retail outlet near you. If you own your equipment, be sure to check My Device Info to find out if your equipment is compatible with your internet speed.

If you rent equipment through Comcast and have been notified that you are eligible for an equipment upgrade, please visit www.xfinity.com/equipmentupdate.

Before purchasing a new modem, be sure to check My Device Info for compatible devices..

Benefits of Renting From Us

One advantage of renting an Xfinity xFi Gateway is that we regularly update our firmware automatically, so you don't have to check for new updates. Gateways also support the fastest internet speeds over WiFi to ensure you're getting optimal performance and coverage throughout your home. Learn more about the benefits of renting an xFi Gateway.

Using a Modem and Router

Updating your TV Box FAQS

What happens if I don't replace my TV Box?
If you don't replace your TV Box, you start losing HD channels, or in some cases, all channels.

I have more than one TV Box – how do I know which one(s) must be replaced?
Tune to channel1995on each of your TVs and follow the instructions. It lets you know if a TV Box is compatible with the upcoming changes or needs to be replaced. (TV Adapters – devices that are approximately the size of a deck of cards, don't need to be replaced.)

What happens if I have a DVR?
If you have a non-X1 TV Box, saved recordings will not transfer over and recordings for future programs will need to be reset on your new TV Box.Learn more about setting show recordings.

If you have an X1 TV Box, the recordings that are physically stored on your TV Box and on the cloud will be transferred during your move. Any recordings not available in the Cloud will be lost. These include:

• Recordings older than a year.
• Recordings deleted from the Cloud because they exceeded the current Cloud capacity of 60 hours (150 in some locations*) Cloud capacity.
• Recordings on adult programming and pay per view events.
• Recordings that failed in the Cloud.
  
  

*X1 Cloud DVR storage hours are increasing from 60 to 150. We began launching this update at the end of April 2020 and expect it to be complete by June 2020.
