What is the DOCSIS 1.0 device replacement program?

Background: Starting in the fall of 2008, Comcast began to upgrade our network to the DOCSIS 3.0 standard.  DOCSIS 1.0 is the original standard for how cable modems work.  Most of the active devices in our network comply with DOCSIS 1.1, DOCSIS 2.0, and now DOCSIS 3.0.  However, a very small number only comply with DOCSIS 1.0, including some that may say they comply with DOCSIS 1.1.  

Benefits of Upgrading to a Newer Device: Upgrading to a device that supports a more recent DOCSIS version will enable our customers to have access to higher speeds, greater reliability, and other benefits. 

Comcast's DOCSIS 1.0 Device Replacement Program: If you have a DOCSIS 1.0-only device that is working on our network now, and your account is in good standing, it will continue to function until January 15, 2010.  However, new or returning customers will no longer be able to use DOCSIS 1.0 device beginning June 2009.  

For our existing customers, we will be in contact with you prior to January 15, 2010, in order to replace your device with one that supports more recent DOCSIS versions, which will improve your high-speed Internet experience.  

If you lease your device from us, it will be replaced at no additional cost, and an easy-to-use, self-installation kit will be mailed to your home.  If you own your own device, you will need to either purchase a new one or you can begin leasing one from Comcast, so that you need not replace one at your cost in the future.  

If you would like to replace your device now, please click here to chat with a customer service representative now, and ask for a self-installation kit to replace a DOCSIS 1.0 device.
