I'm not sure what to do? Mini questions.

I updated an older post of mine about my Roamio basic and mini having issues. Currently, everything is ethernet. I'm now contemplating going MocA. But looking at some of the threads, I am left confused. Not to mention other people are having issues with moca as well. :(



Would my Roamio stay on my regular ethernet network??? Or do the roamio and mini have to be on a moca network?



What kind of hardware do I need (this may be the deal breaker)? Do I need a moca adapter for he incoming cable and each device (roamio, mini)?



I'm going to reset everything on my ethernet network one more time today but I am beyond frustrated with everything tivo at the moment. It sucks paying hundreds of dollars and not being able to watch tv in the bedroom. Seems like such a simple task.
