In other words POE > Modem > Moca > Moca > eero = fail, but POE > Modem > Moca > Moca > linksys router > eero = success. When I connect the moca adapter to the gateway eero it (the eero) just flashes white for a couple minutes and then turns red however, if I run the moca adapter into my old linksys router and then into the gateway eero it works perfectly. The POE coax runs into my modem, which connects to a Hitron moca 2.5 adapter in the closet and then runs through the building by coax into my apartment where it feeds into another Hitron moca 2.5 adapter, see diagram. My modem is in a closet next to the Comcast box in another part of the building (this is necessary - I can't move the modem).
