Unfortunately I can't advise you on the MoCA connection but an easier solution might have been what is known and EOP or Ethernet over power. Essentially you use the electricity circuits already in your walls like eternity cables. I believe on Amazon.com a pair ran for $50 and $80 for a quad. Very reliable and only require a simple patch cable to go from the router to the outlet plug (which can then support another device for power) and then vice versa from another outlet plug to device such as your gaming systems. Very easy and even more plug and play friendly than MoCA seems to be from your post.
