Thanks for your help, am new to this forum and TiVO. I have an OTA Roamio, connected to the antenna and the network connection is wireless. I need to connect a Mini in the basement. I have spent a couple of days researching as I generally try and find the answer myself rather than pester others, but alas, I have located conflicting information and would like to get accurate info to go forward. I am also sure that my initial "simple" question will lead to others depending on the answer. I have attached a diagram for clarity. The simple first question is can I attach a single MoCA bridge as in the diagram, OR does the bridge need to connect at the router? ( am guessing router ), the followup is in either case with the mini MoCA attached, will I experience issues with a wireless ethernet connection to the Roamio? The Issue I have to deal with is that each of the grey areas in the diag are "rooms" I cannot add physical cables ( coax or cat5 ) as the house is a multilevel nightmare.
