    When watching live TV on my Roamio Plus (6 tuners), I use the INFO button followed by DOWN to show a list of channels that are active on the tuners. Those with a red dot are currently recording, while those with a gray dot are only buffering. Using RIGHT and UP/DOWN lets you select a tuner if you want to switch. Tuners that are in use by a Mini are marked "In use by ...." and can't be selected from the tuner list.

    No, the tuners in the TiVo are always active (ignoring standby). My TiVos are configured so that hitting the TiVo button puts the live TV in a small window in the upper/right corner of the screen, so tuner allocation doesn't change by hitting the TiVo button.

    Use the tuner list, as described above. While watching live TV, hit INFO and DOWN to display the tuner list.

    That last photo reminds me of California a bit. It looks like you might have most all of your electric, catv, phone etc. right in those boxes. The upper right looks like it might be your electric service box where your breakers are located. There is smaller flush mounted box which may have your coax connections. Also, I see a green wire 9normally used for a ground running up along the conduit which may be connected via a clamp to that conduit. Not sure what the other boxes are, looks a bit like possibly phone and or an old Fios ONT.
    In any case, these boxes are the place to explore for your connections. Good luck

    Which of the cables heading left out of the image, the top or bottom cable, is the cable that you followed from around the house?

    And do you have a pic where the coax enters your other upstairs rooms from outside? (I believe you said that you have coax outlets in 3 rooms upstairs, but only one upstairs entry point has been pictured.)


    This doesn't seem correct, from my understanding of previous posts and what I can make out from the images posted.

    Isn't the "downstairs inside splitter" just on the other side of the wall at that entry point beneath the DirecTV device, per your earlier post....?


    p.s. My current (mis)understanding of your cabling...

    The bottom cable is the one I followed around the house. You see an entry point to one room upstairs.

    There's another entry point if you follow the top cable that's heading left. Shortly off-screen is the other entry point.

    The 3rd upstairs room also has an entry point. At some point on the roof, there must be another splitter that has one end go to the 3rd upstairs entry point.


    As to the image you posted:

    https://www.tivocommunity.com/community/index.php?attachments/patchwork-jpg.36204/

    Yeah, there are 3 lines under the eaves. That's why it was confusing to me. One of those might be diverging and going to upstairs room # 3.

    All of those coax lines near the electrical box area are coming from the roof.

    I haven't tried to open one of the electrical boxes again. As I said, I might do it on Tuesday.

    Either I'll be able to open it; or I'll take more pictures of the area to see if we can get any more clues; or I'll have the technician come and figure out how to open it and install the MoCA filter.

    I have the MoCA filter now, it arrived.

    Now that I'm looking at it closely, I just have to ask, to make sure.

    This is NOT a MoCA filter coming from my downstairs wall plate, correct?

    I also don't see anything like that coming from my upstairs wall plate, just a regular coax connector:

    No NOT a MoCA filter, it's just a normal compression fitting.
    Your second photo is just a plastic cover with a hole drilled in the center, then you see 2 different style compression connectors joined with a barrel connector.

    Sorry for the delay. Once I realized that I needed a screwdriver to open the electrical box, and given how weekday evenings didn't have the best lighting conditions, I thought I would wait for the weekend to open the box.

    Here's the big box, with the splitter:

    https://i.imgur.com/M3Jiyo5.jpg

    https://i.imgur.com/pwIp95T.jpg

    So I should put the MoCA filter before it reaches the IN port?

    After I installed it, if I can still watch live TV and get internet, then it means I installed it correctly?

    After I install the MoCA filter, should I change my Tivo settings to use a MoCA connection instead of an Ethernet connection, even though I don't have the Tivo Mini yet? If I do change the settings, can I still verify it's working correctly without the Tivo Mini?

    The MoCA filter's installation should have no effect on tuning/viewing/recording content on your DVR, the XL4, even if installed in the wrong location. The MoCA filter's function is to block MoCA signals from leaving the house, and leaves the CATV/BB signals mostly untouched (w/ just a minimal signal loss). You wouldn't see any effect from an incorrect installation until you attempt to initialize your MoCA network on the XL4 (e.g. an improperly installed MoCA filter might result in the XL4 reporting visibility of MoCA clients that you don't have) or attempt to connect a MoCA client from another location in the home (e.g. the client may not have connectivity to the XL4, may connect to a MoCA node outside your home, etc.).

    The pics don't provide sufficient detail to understand how this device connects to your coax lines (from the roof and the line from the ground). Did you open the other smaller plastic box? Did you trace all coax lines to just the big box? Can't the big box's whole front panel/door be swiveled open, rather than just the lower right panel?

    Can you trace the coax lines connected to this device to where they're coming from... the coax line coming from the ground, coax runs coming from the roof, other? And when you can afford a brief Internet outage, you could try disconnecting either of the output ports from the device and see which output port affects your Internet connection.

    It's possible that this single device provides the main split for your coax plant and, if so, the "PoE" MoCA filter would be installed directly on its input ("IN") port, rather than via a short coax cable:

    p.s. Also, from what I can see from the pics provided, that splitter (actually a "tap") isn't connected to Ground, so that issue remains open; though it appears also possible that the green wire mentioned by @fcfc2 is feeding into the big box via the same opening as the incoming coax cable, and there's a ground block hidden behind the unopened larger panel on the big box. For that matter, it's also possible that a "PoE" MoCA filter is also already (sub-optimally) located behind the unopened panel.

    p.p.s. My current understanding...

    The XL4 will remain connected via Ethernet and will maintain its Ethernet configuration, necessary to bridge the MoCA/coax segment over to the router. When ready to activate MoCA bridging within the XL4, you'll additionlly configure the XL4 to act as a MoCA bridge.

    That said, at any time you could enable the MoCA bridge within the XL4, before or after you install the "PoE" MoCA filter; however, you wouldn't want to leave MoCA active in the XL4 without the "PoE" MoCA filter being in place. (e.g. You could enable MoCA in the XL4 *before* putting the "PoE" MoCA filter in place simply to see if the XL4 is able to see any other MoCA nodes -- e.g. neighbors' gear. These foreign nodes should then NOT be visible once the "PoE" MoCA filter is properly installed.) This extra step isn't necessary, so once you know where the MoCA filter needs to go, it's simplest to just get it in place.

    Without another MoCA node beside the XL4 on your coax plant, the XL4's MoCA bridge will report as down. You'll need a Mini or some other MoCA node reachable on your coax plant to validate the XL4's MoCA bridging.

    Yes, your new understanding is correct.

    Here are more pics from the roof, going downwards.

    I couldn't open the big box's whole panel. The best I could do was tilt it a little toward me, but not actually open it. I could only open the lower right panel on the big box. There's a message that says customer access only for the lower right panel too.

    Here's also the other small plastic box:

    It looks like it would be hard to unscrew to coax here, if I had to.

    My best suggestion for you is to call Comcast and tell them you are using MoCA and need to have them install a MoCA filter for you. It is possible they already have one installed in a drop box or wherever, but even if you have to pay, this is about the only way I can think of for you to get your MoCA working. I would also make it my business to ask the tech where you can get access to your wiring.

    I have my appointment with Comcast set up for September 16th.

    When I made the appointment in August, I asked them about the MoCA filter, but they were unable to provide any information over the phone. They just kept asking whether I had a problem with the service.

    So the pictures I posted in post # 51 isn't enough, or isn't the right place?

    I had a Comcast tech out here about three months ago, I was seeing random pixelation. While checking everything he installed a MOCA POE filter. I said I didn't think I needed it, my Mini's use ethernet. He said I did use MOCA on the Comcast side and their current policy was to install a POE filter in any residence that didn't already have one.

    Thank you. Good to know that from your experience, they knew about the POE filter.

    Hopefully the one that comes to my place can either check if there's one installed, or install the one I will provide.

    Based on the pictures I posted in post # 51, does it look like I already have a POE filter installed?

    Can you see anything that looks similar to the following...

    MoCA filter examples.png

    The "PoE" MoCA filter may be installed behind the portion of the panel you've been unable to open, including the possibility that it is built-in to the ground block (also hidden behind the closed section of the panel;); e.g.. But no way to know for sure without opening the panel, which the tech will be able to do when they arrive.

    The “PoE” MoCA filter’s current location will likely be OK, but the tech should have installed the MoCA filter on the input of the tap (the component over in the customer-accessible section of the panel) for best performance.

    https://www.tivocommunity.com/community/index.php?attachments/big-box-annotated-jpg.36298/


    ... though the tech installing the filter where they did validates the earlier comments that the “PoE” MOCA filter might be hiding behind the unopened section of the panel.
