Why It's Important to Upgrade End of Life and Unsupported Equipment

This document provides information regarding devices that are no longer supported for XFINITY customers or identified as End of Life (EOL). You can enter device information on mydeviceinfo.xfinity.com to see if a specific device is unsupported or EOL.

What Does It Mean When a Device is No Longer Supported?

A device that's no longer supported/EOL by Comcast is any XFINITY Internet or XFINITY Voice device that needs to be replaced after being made obsolete due to changes in technology. Older equipment such as cable modems were not designed to support the faster speeds and improved security features that are currently available.

For example, we have upgraded our network from the original DOCSIS 1.0 and 2.0 standard to the significantly improved and much more recent standard. If you currently use a DOCSIS 2.0 or a select DOCSIS 3.0 device, you will not be able to enjoy the full benefits of our service such as higher speeds, improved security and better reliability!

In most cases, the modem's manufacturer has stopped providing support for the device. Such support usually includes firmware updates and bug fixes. On occasion, we will identify a device that's defective and is no longer suitable for use with our network.

If a device is no longer supported by Comcast or EOL, this basically means we will no longer install the device, either as a new or replacement device. In addition, it means we no longer recommend that customers purchase these devices, whether new or used. It is also an advance warning that the device will soon need to be replaced.

Devices that are no longer supported include all DOCSIS 1.0, 1.1 and Non IMS devices, which will no longer work on our network or be compatible with our network and/or services.

You can find out if your current device is supported by visiting mydeviceinfo.xfinity.com.
