The newest gateway's have a 3rd wifi network for the Xfinity Home equipment, and don't need the sidecar.
I can confirm this is correct. The xHome router (called the sidecar router) is really only intended for use when a customer is using their own modem for XFINTY Internet services. If you're using the Comcast supplied XB2 or XB3 gateways, these models have the functionality built into them, making the router duplicative.
