A:Answer This satellite can only talk wirelessly back to an Orbi Router. This is an add-on satellite (extender) for an existing Orbi Router system.
The Orbi Router (sold seperately) can be used in AP mode with a Cable modem Router combo and not change anything with your current setup, but I would consider turning off the wireless and routing functions in the router part of the cable modem and just let the Orbi Router handle the Routing functions instead. Depends on which routing functions you want more, those provided by the existing cable modem/router, or those that could be provided by the Orbi Router.
