Most residential installers don't put the router in the best place for performance, they put it in the easiest most convenient place for them.

Around here 90% of the time they stick them inside the metal utility box in the laundry room. You could literally not pick a worse spot.

And yes, splitter at TV, one leg to cable box, one to MoCA extender.

Thanks... I'm learning. Good point moving the Comcast gateway to right near the TV. This means I can "drive" the TV directly with an ethernet cable as a second input. However, moving the Comcast gateway to the TV makes it maybe worse wifi strength at the other end of the house where my wife's laptop and printer are. So if the MoCA single box would work that might be the easiest solution. I think I should update my diagram for y'all.
