Not exactly the same thing, since often the problem with MoCA is the coax and the connecting components between the MoCA nodes. The above test attempts to simplify the connection, in order to verify basic MoCA functionality of the gateway, primarily, but also to demo a successful Mini MoCA connection. If the simple test above doesn't work for connecting a Mini, the MoCA LAN functionality of the gateway is suspect. Speaking of the gateway, I haven't seen that MEB1100 before, but found a great description from @fcfc2 over on another of his haunts, the DSLReports forums, here: Regarding the MoCA WAN issue, the latest Fios Router Arris NVG468MQ comes with a separate MoCA adapter, the Arris MEB1100, which appears to be used exclusively to convert the ONT coax MoCA WAN to the router's Ethernet WAN port on the router. But if that is the case, there is absolutely no reason that Arris MEB1100 could not be used with any brand of router. What possible speed tiers it would support is unknown but it appears that there is a current MoCA WAN adapter out there. I did a quick google search on the Arris MEB1100 but I couldn't find any decent information or specs to see which MoCA standard it supports or much of anything. Absent any additional documentation, though, I'm a bit baffled as to the purpose of the USB cable between the MEB1100 and the Arris 468. Your diagram looks OK, otherwise, aside from the Minis and their associated coax connections being missing. Also, I'm curious as to the specs of the splitters in use; can you provide model numbers for the splitters?
