View information on approved modems for use on all Cox High Speed Internet packages, excluding Gigablast.

Solution

The DOCSIS 3.0 and 3.1 devices listed below meet our service and performance requirements and are certified for use with all Cox High Speed Internet packages, excluding Gigablast.

  • Speeds are not guaranteed and may vary based on individual circumstances.
  • Cox does not promote or endorse any particular device or manufacturer for your use.
  • Review the modem manufacturer’s specifications to choose a device based on your individual needs.
     

If you have a DOCSIS 2.0 device, Cox strongly recommends that you upgrade to a DOCSIS 3.0 device in order to receive optimal speeds. Future speed increases may not be achievable with these devices. To upgrade your device, visit www.cox.com/upgrademymodem.


DOCSIS 3.0

DOCSIS 3.0 devices are required for all new Cox High Speed Internet customers. Current Cox customers should ensure they have a DOCSIS 3.0 device in order to consistently receive optimal speeds. Additionally, Ultimate customers are required to have a DOCSIS 3.0 device with a minimum of 16 x 4 or higher channel bonding to achieve package speeds.


DOCSIS 3.1

DOCSIS 3.1 devices listed below are certified for use with all Cox High Speed Internet package speeds, excluding Gigablast.

  • Cox-certified DOCSIS 3.1 devices are backward-compatible with DOCSIS 3.0 technology.
  • DOCSIS 3.1 service may not be available in all areas.


Special Recommendations for WiFi

  • If your primary Internet usage will be via wireless devices such as laptops, tablets, and mobile devices, Cox recommends a dual band 802.11-AC WiFi modem. Dual band 802.11-AC WiFi modems provides the best in-home WiFi experience.
  • To learn more about WiFi, visit www.cox.com/wifisupport.
