Interestingly, that did not work for me. I don't have any STBs connected anymore (cut the cord), but the way I have my MoCA network set up is ONT to Router via Ethernet, then Ethernet from Router to a switch. My Motorola MoCA adapter is plugged into the switch with an Ethernet Cable, and a coax cable runs from there to a Holland 8-way MoCA-compliant cable splitter (I replaced the one that was installed with FIOS) Holland 8 way Splitter
