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

An 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 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 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, improved security and better reliability.

In most cases an EOL modem means that the device'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 is defective and is no longer suitable for use with our network.

EOL 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 EOL, it will subsequently move to end of support (EOS) status. This includes all DOCSIS 1.0, 1.1 and 2.0 devices. This means that when a device reaches EOS 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 EOL by visiting the DOCSIS Device Information Center.
