FAQ

When choosing an Xfinity cable modem, look for features such as DOCSIS compatibility (preferably DOCSIS 3.0 or 3.1), high download/upload speeds, multiple Ethernet ports, and compatibility with your Xfinity internet plan. Some modems also include built-in Wi-Fi routers for added convenience.

No, not all cable modems are compatible with Xfinity. It's important to choose a modem that is on Xfinity's list of approved devices to ensure seamless activation and optimal performance.

To activate your Xfinity cable modem, connect it to your coaxial cable and power source, then follow the on-screen instructions at xfinity.com/activate or use the Xfinity mobile app. You may need your Xfinity account information during the process.

Some Xfinity cable modems support voice services (telephone), but not all do. If you need phone service, look for modems labeled as 'voice modems' or 'telephony modems' that are compatible with Xfinity Voice.

Using your own Xfinity cable modem can help you avoid monthly rental fees, potentially offer faster speeds, and give you more control over your home network settings. It also allows you to choose a device that best fits your needs and preferences.
