I have a base Roamio and a Tivo Stream coming Tuesday. Do both of them need to be wired to the router? I have a Apple Airport extreme and a Apple Airport express currently, with the extreme hooked to the cable modem, and the Express as a (wireless) extension to the network. The express only has connection so if I have to hook both the roamio and the stream up, I am out of luck. We are cutting Directv and going with a Roamio and 3 Apple TV's, I have the HD Antennas hooked up and all is good there.
