  • CENTURY LINK

Compatibility of the Motorola MB8611 with Major Providers

Most major U.S. internet providers support DOCSIS 3.1 modems, including the Motorola MB8611. However, compatibility can vary based on specific plans, infrastructure upgrades, and regional differences. As of 2026, the following points are relevant:

Comcast Xfinity

Comcast Xfinity generally supports DOCSIS 3.1 modems, including the Motorola MB8611. Customers should verify their local compatibility and ensure their plan includes DOCSIS 3.1 support. The MB8611 is often recommended for Xfinity users seeking high-speed internet.
