Does my MoCA have to be connected to the cable wire from the street? My current set-up is the box on the side of my home, has a 5 way splitter. The street cable is connected to the splitter and the outs from the splitter are dispersed to the multiple rooms of my house. Can I connect the moCa to any two coax cables and have the ethernet active or MUST moCa #1 be connected to the coax coming from the street?
