So here's my setup: Basement data closet has a cable modem/router with 4 outputs. This connects to 4 CAT jacks, which are run to various rooms in my house. Ideally, I want to set up my Airport Extreme in my living room, and have it both broadcast the wifi network, and use the ethernet ports to drive hardline connections for my Apple TV, PS4, and DirecTV box. I want to then use my Time Capsule in my basement to use as a wireless backup, wifi extender for the basement, and use the ethernet ports to hardline my Apple TV, PS3, and DirecTV box for the downstairs TVs. Is this possible? It seems I have to run the Airport Extreme in bridge mode so it doesn't interfere with the router functions of the cable modem. Is there a better way to do this? Any networking gurus able to help me?
