Support XFINITY Internet End of Life Devices


This document provides information regarding end of life devices for XFINITY customers.

If you are a Comcast Business customer, please see Ensure you have the most current Comcast Business equipment for end of life (EOL) information for business equipment.

What Does It Mean When a Device is End of Life (EOL) or End of Support (EOS)?

An end of life (EOL) device is any XFINITY Internet or XFINITY Voice device that needs to be replaced after being made obsolete due to changes in technology. Older devices, such as cable modems, were not designed to support the faster speeds and improved security features that are available today.

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

In addition, in most cases an end of life modem means the device's manufacturer has stopped providing support for a device, such as firmware dates and bug fixes. Occasionally, we will find a device that is defective and no longer suitable for use.

End of life 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.

Typically, if a device is identified as end of life, it will subsequently move to end of support (EOS) status, such as a DOCSIS 1.1 device. This means that when a device reaches end of support status, it 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 end of life by visiting the DOCSIS Device Information Center.
