@ploog I was just able to connect the two adapters to each other, and the MoCA lights both came on. Then connecting one of them to the current router brought the LAN light online as well. Do they need to connect back to this router long term through the ethernet? It had been my understanding that they only needed to connect to the Coax cable coming from the Fios line (and of course power and their own routers)

I havent been able to find any instructions along those lines so far

@ploog Correct, the caox port of the NVG468MQ is unused. I am planning on having 2 remote goCoax locations in addition to the frontier location

-The current router that connects to Frontier's MoCA adapter is an ARRIS NVG468MQ -The Frontier device is currently set to WAN -I am pretty unfamiliar with all of this so this may be the wrong answer, but currently the ARRIS router has the ethernet cable running from the Frontier MoCA device connected to the 'ONT' port. Aside from that, the remaining ports are all open at this time. -I purchased 2 goCoax WF-803M adaptors. So far, this is all relating to the first one, but I am sure I'll have just as much trouble with the second one, based on my inexperience with this stuff
