DOCSIS Device Compatibility and Capability

photoThis site provides a list of all currently approved cable modems and EMTA devices. Use this site to ensure your device is compatible with the service level that you subscribe to. For additional information on End of Life (EOL) devices, please review the EOL FAQs.

Comcast strongly recommends customers only purchase devices that include a warranty and/or return policy. Cable modems and eMTAs operate with firmware/software and could make the device defective and inoperable if compromised in any way.
