If you’re accessing XFINITY Internet with an old modem, you’re not taking advantage of our new speed plans. Consider upgrading your modem.
Upgrade Your Modem
If you want to enjoy our faster Internet speeds, such as Blast!, a DOCSIS 3.0 modem is required. You can lease a DOCSIS 3.0 modem from us, buy an approved modem at a retail outlet near you (see DOCSIS Device Information Center for compatible list) or check to see if your existing modem is approved at the DOCSIS Device Information Center.
If you lease a modem through Comcast and have been notified that you are eligible for a modem upgrade, please visit www.xfinity.com/deviceupgrade.
