Question on FIOS with Ethernet from ONT and MOCA

I have FIOS and my internet is on ethernet which runs to my can in my master bedroom which contains my coax feed and router that splits to all the rooms in my townhouse. I have ethernet in my bedrooms and kitchen but no line in my family room where my Roamio is located. I purchased the Actiontec MOCA adapter (2) and am trying to figure out how to set it up.



If I connect the Actiontec to the Coax and ethernet ethernet in the can in the master bedroom will enabling MOCA on the Roamio give it an internet connection and allow my mini to work as well? The mini is connected to the ethernet feed in my master bedroom.
