Currently I only have OTA/Antenna TV. Antenna coax in to a splitter, with one coax line running to the back of the house, while the other line attaches to the Roamio OTA. The Roamio OTA is close to my internet router and is connected to the router by an Ethernet cable. I want to add a mini at the back of the house using a Moca network. It would be difficult (not impossible) to run an Ethernet cable to the location but it currently has a coax connection. I think what I need to do is: (I have attached a sketch of current and proposed connections in a PDF.) I am considering using 2 Actiontec ECB6200's (other recommendations?) Moca devices to establish the Moca network. I think what I need to do is remove the current Ethernet and coax connections from the Roamio OTA. I would add a splitter on the coax that was running to the Roamio and off of one leg I would add an Actiontec and from the Actiontec I would have a coax connect to the Roamio and an Ethernet connection to the Roamio. From the second leg I would attach it to the second Actiontec and then attach the Actiontec via Ethernet to the router. Then the mini will have the required access to the Roamio? Am I on the right track? Any better ways?
