Thanks I will try that. I would assume I would need to reset the modem or power cycle it after I plug the sidecar and my airport into the different ports?
Power off your XB3 then make the connections to your equipment. Power up the gateway, and then power up your equipment. This should eliminate any odd issues with your Airport not connecting to the Internet (I have one myself and if I don't power cycle in a particular order, it screams at me).
