    I just moved into a new house, and switched to a Roamio OTA connected with an antenna in the attic. I need some help in figuring out how to get the mini's connected.

    Here is my setup.

    Living Room -
    • Roamio OTA connected to a coax that runs into the antenna in the attic.
    • Frontier FIOS router (Arris NVG468MQ) is next to the Roamio OTA. The router is connected via ethernet. This router can be setup as a MoCA bridge.

    Attic -
    • All cable runs to each bedroom conveniently come together right next to the attic access.

    Can I install a 2-way splitter behind the Roamio/Router to send MoCA up to a slitter into the attic? @krkaufman....any chance you can help me out?

    Yep. Though you could also use an antenna/satellite diplexer, rather than the 2-way splitter, to lessen the signal loss. (SAT port to router, VHF/UHF port to DVR; more info >here<)

    As for the splitter in the attic access location, with just one coax run to the DVR/router location you'd be looking at Options 1-3 in the following graphic:

    (If you had 2 runs, Option 4 would be the way to go.)

    Oh, the DVR would be wired via Ethernet to a LAN port on the router, of course.

    Ok...so I setup everything as depicted in Option 3. Everything in option 3 is in the attic. The "to dvr" line from the diplexor is going to the jack behind the TV. At that jack, I have a splitter with one line going to the Roamio OTA and the other going to the Arris NVG468MQ. Is this all correct?

    I cannot get the minis to connect to the MoCA network. Is there a setting on the router that needs to be turned on to enable MoCA use?

    Yes, though, as mentioned earlier, you could have used a second diplexer at the DVR/router location, rather than the 2-way splitter, to surgically redirect the signals to their respective devices, for a bit of signal savings. If the OTA signal is satisfactory, then a splitter is fine (even better, since you then don't have to worry about which port is being used, which can be confusing months/years down the road).

    Good question; likely, but I'll need to check. Do you have access to the router's config UI?

    Also, a quick test to eliminate the coax plant as the issue would be to hook a MoCA adapter or a Mini directly to the router's coax port, using a short coax cable. Once this direct test works, then you can tackle getting things working across the coax plant.

    I only had the one diplexor, so I went with a splitter behind the TV to save some time. The signal stayed the same, so no worries there.


    Yes...I do.

    One step ahead of you on that one! I tried hooking the mini up directly to the router, without success.

    I did change this MoCA setting to enable, without success.

    I still see this on the main summary page.

    I came across this thread. Is it possible that Frontier has disabled this option due to my 500/500mbps exceeding the capability os MoCA?
    Frontier Fios MOCA question...

    Different issue, I expect. I think I covered that >here<.

    My guess is that MoCA is just not enabled by default on the NVG468MQ. (edit: Looking into it.)

    (edit2: Bad guess, per your prior post)

    And accessed the Mini's network configuration page to ensure it was set to MoCA client, "Auto" channel, no privacy, etc?

    I just reset my NVG468MQ to factory default, and was able to connect a TiVo Bridge to it with no problem. It took about 10 seconds for the "coax" LED on the TiVo Bridge to illuminate, indicating a successful MoCA LAN connection. (With the NVG468MQ's 'Coax (MoCA)' configuration page reflecting the status change from 'Down' to 'Up.')

    edit: p.s. And the TiVo Bridge was able to link-up whether I had the NVG468MQ's 'Network Controller' setting enabled or disabled.

    Yeah, disabling 'MoCA PHY Enable' killed my TiVo Bridge's MoCA link ... and re-enabling this setting, it took about 15 seconds from hitting 'Apply' for the TiVo Bridge to re-establish the link.

    edit: p.s. Demerits to the firmware programmers for not listing MoCA status as "Disabled" (rather than "Down") when this setting is actually disabled.

    Great news! I am up and running! Bonehead move....I had the POE filter on the wrong end of the diplexor. Not sure why the mini would not work the first time I connected it directly to the router. I tried again and it worked fine. That lead me back up to the attic to review my connections. Thanks again @krkaufman ! This is the second time in 4 years that you have got me up and running with my minis. I REALLY appreciate it!

    Ah, great to hear!

    And I got some good (and bad) out of it, as well. I finally powered-up a NVG468MQ I'd bought quite a while back (good), but have found my device's firmware to be sub-optimal, per a SNB forums thread discussing the router (link):

    Searching high and low I was unable to find a MoCA statistics page, and the above post explained why. Not sure there's any way for a non-Frontier customer to get a firmware update on one of these.

    p.s. My firmware version: 9.2.0h3d58

    @krkaufman Just curious... in options 3 & 4 in post #2 above, what is the purpose of the POE filters on the splitters as opposed to just using a terminator?

    My failure to definitely lock down which provides better performance, so I've typically kept the "PoE" MoCA filter in place to normalize the configurations.
