FAQ

A modem that is Xfinity compatible has been tested and certified to work seamlessly with Xfinity Internet services, ensuring reliable connectivity and optimal performance for your home network.

Many Xfinity compatible modems are standalone devices that provide internet access only. If you want to create a Wi-Fi network for multiple devices, you will need a separate wireless router or a modem-router combo.

To activate your Xfinity compatible modem, connect it to your coaxial cable and power source, then follow the on-screen instructions at xfinity.com/activate or use the Xfinity app for a guided setup process.

Some Xfinity compatible modems, known as gateway devices or telephony modems, support both internet and Xfinity Voice services. Check the product specifications to confirm voice compatibility.

Owning your own Xfinity compatible modem can save you monthly rental fees, give you more control over your network setup, and may provide access to the latest features and faster speeds compared to standard rental equipment.
