Support XFINITY Internet Wireless Gateway Guides


The wireless gateway is your all-in-one product that connects your XFINITY Internet and XFINITY Voice, and provides WiFi connectivity for your home, so there's no need for a separate wireless router.

Need help setting up and using your wireless gateway, or want to learn more about the great features included with your Comcast services? No problem.
