I see no reason that it wouldn’t, but I’m confused why that middle adapter is there at all. Do the 2 coax outlets the outside moca adapters connect to not run back to the main junction?
I drew up the diagram pretty quickly. That middle adapter isn’t there. For the upper right portion, it will go:
Modem/Router > splitter > splitter > MoCA (times two)
If that makes sense.
Right now, in that room, it’s:
Modem/Router > splitter > MoCA
This works rather well. I just didn’t know if adding another splitter layer so I could add another TV would work.
