Can I have a Roamio hooked up to wireless and a Tivo Mini hooked up to moca?

Hooked up my new Roamio just fine to wireless (Cox cable & internet) and it is working great. Now I'd like to hook up a tivo mini. While I realize that the mini needs an ethernet connection, can I create a moca connection and have it work with the wireless Roamio?



I'm not tech savvy as most of you are on these forums. The way I grasp the moca connection is that I have a splitter that splits the cable between internet and TV. The internet cable would be attached to an adapter which in turn would be used to the internet connection to the mini? Do I have it right?



Any help would be really appreciated.
