I need help with configuring a new moca for Tivo network in our home - the main Tivo is a Roamio basic 4-tuner and second unit will be a Mini. I have searched and searched through this forum but have not found my exact scenario. I have attached a diagram that shows my current setup. Basically Comcast cable input to house is split 2-ways: one coax to the internet cable modem and the other coax that will be split 2-ways. One coax is already going to my current Roamio. The other coax I will send to the Mini that I just purchased. As the diagram shows, my modem and router and Roamio are all in the same room. My questions to this forum are: How many Moca adapters do I n eed? I am not 100% sure that I need 2 since I'm confused about comments I've seen about connecting router to Roamio via Ethernet. Where would adapter(s) be installed? Please confirm that I would need POE filter and where that would be put? Should I upgrade the splitters (they are just basic ones that cable company provides)? Thanks so much for any advice I can get!
