About DOCSIS 3.0

Upgrade Your Speed

DOCSIS 3.0 is the next generation of DOCSIS (Data Over Cable Services Interface Specification), an international telecommunications standard that lets cable television operators add high-speed and telephony data to their current cable TV systems.
 

With DOCSIS 3.0, you’ll experience significantly faster speeds, so you can make the most of your online experience. DOCSIS 3.0 also opens the door to new Internet technologies.

XFINITY Speed Plans

When DOCSIS 3.0 becomes available in your area, you may find your Internet speeds automatically increased. You'll also have the option to upgrade to new speed plans.

Upgrade Your Equipment

To take advantage of DOCSIS 3.0, you need a DOCSIS 3.0 modem. DOCSIS 2.0 modems will still work with our speed tiers (except for Blast! and Extreme 50), but you won’t experience the blistering fast speeds now available. We also recommend upgrading to an 802.11n wireless router; 802.11g routers only support up to 20 Mbps. If you lease your modem, router, or gateway device from us, we’ll upgrade it at no extra charge.
 

If you already have a DOCSIS 3.0 modem, you may need to power cycle it to take advantage of our new, faster speeds. Check out how to power cycle your modem.
