Ok, 82 year old mother-in-law has a 4-tuner Roamio (not the plus, pro or OTA model). Someone at Tivo should be beaten with a stick for the dumb-ass Roamio naming... The Roamio is hard-wired via Ethernet. No MOCA nor WiFi involved. She has Time Warner cable (on their most basic, cheapest, slowest possible connection). I installed an SB6121 cable modem for her a while ago. It's fed into a DLINK router and then CAT5 to the Roamio. This works fine. The location for the Mini currently only has coax. I could run ethernet to it, but there's only so much effort and tools I want to be dragging up from DC to Buffalo to make this all work... Not to mention fending off the MIL commentary regarding holes being drilled... Easiest solution would be to have the Mini use MOCA, correct? The trick being getting a MOCA network set up, as the 4-tuner Roamio cannot act as a bridge, also correct? The wrinkle is I'm sure she'll soon ask for a 2nd Mini for a TV in another room, also currently served only by coax. So a MOCA network would seem like a better plan that my stringing multiple CAT5 lines all through her basement joists. So what widget am I best served using to create an Ethernet to MOCA bridge for this Mini? Simple is better, I don't want to go through the hoops of using an Actiontec router. Sorry if I've missed this, feel free to point me to the post that explains this particular kind of scenario.
