How to Upgrade Your Modem

Overview

Because outdated equipment and firmware can slow down what would otherwise be a fast connection, you'll want to make sure your network setup is always up-to-date to get the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 mydeviceinfo.xfinity.com 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 mydeviceinfo.xfinity.com 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

If you don't have an Xfinity xFi Gateway, you'll need to periodically check for firmware updates. Generally, you can check for these updates through your router's administration site. For specific instructions, please see your router's user guide.
