    There are 392 threads in this sub-forum. 13 of those threads contain one or more posts that have the term "V87" in them. Thats 3.13%.

    There are 7,875 individual posts in this sub-forum. 26 of those posts contain the term "V87" in them. That's 0.33%.

    IMO, that's not numerous.

    You know your wireless is sh***ty, but you seem oblivious to the fact that the coax cables in your house can be making your MoCa network even more sh***ty than your wireless network. :confused:

    Can you run 3+ Chromecasts at the same time, each streaming a different show in 1080?

    That's the type of environment that streaming has to work in where things get a little more complex than how you do stuff in your house.

    Rocket science? Hardly. But setting up one Chromecast (regardless of the network condition) and proclaiming "That, folks, is how streaming is done" is pretty silly.

    I'm a CCIE, idiot. Look it up, just in case you don't know what that is.

    And, just for the record, I never said that Moca and Wireless were the same networks. Of course, they're different. The Wireless network is, or should be, far inferior to it's ability to carry network data, video data, given how poor the signal is in my bedroom.

    The comparision is valid. A not very robust wireless network environment, versus a functioning coax cable environment, at least for the cable signals to my bedroom, which work fine, EXCEPT for the Mini.

    Arguing aside...

    Network issue resolution with moca is usually the same.

    - Splitters and barrel connectors between devices should be rated for at least 1000 MHz and not too old/weathered.
    - Any amps in the way should also be bi-directional 1000 MHz. Ideally they're located at the POE anyway.
    - A POE filter is beneficial.
    - There's always the chance a coax line itself is too damaged, old, or not solidly connected somewhere.

    No problem. Non-abusive attempts to help are appreciated. I would prefer to resolve this issue. I would prefer that the Mini to work, rather than not work.

    On another note, about the cabling in the house. This house was cabled with coax in every room. What that means is there are no amplifiers or splitters in the house.

    The Mini has a single run of cable from the wall to it. The Roamio has a single run of coax cable to it. I have not installed any splitters, nor have I found any. It is possible there are some, as they may have been installed when the house was built. But again, I haven't found any. There may be some in the attic. But again, every room receives cable tv signals, and does it perfectly. I have never had any issues with the TV signal in any of the rooms.

    There was an Actiontec Moca Adapter plugged into the Mini, which has been removed. Plugged in or not, it does not make any difference.

    Wow, completely unnecessary. Nobody knows your expertise, and you certainly did not come across as a "CCIE" in your email thread or lack of professionalism. The folks here are trying to help you.

    About a week or so ago, after a TW service visit for a missing channel on my lineup (whole 'nother issue), I started getting V87 errors on both my mini's and I'm also using MOCA from my Roamio plus. I'd note that my coax in the attic is all fairly new, heavy gauge used for my previous satellite setup.
    The only things that changed during that time frame was:
    1) I received a patch (update) due to occasional V112 errors (fixed V112 errors)
    2) TW Service man replaced my 3 way splitter in attic (5-2040Mhz) with his own 3 way splitter.
    3) TW service man took off my POE filter (which was right before 3 way splitter) since he wasn't familiar with what it was/does.

    So I did these three things:
    1) put back my 3 way splitter that I specifically bought for my MOCA network.
    2) Changed my IP configuration on my Roamio and 2 mini's to static IP's.
    3) Put the POE filter back on where I had it.

    Since then I have not had a single V87 error and nothing else has changed other than the two things I mentioned.
    The fact that I started getting these errors on both my mini's after TW switched out my splitter was my problem in my opinion. My dB signals never really changed but somehow his splitter must have not had the same range (it wasn't labeled) as the one I bought does.

    I think I also read that the POE filter helps by reflecting signals back into your MOCA network instead of letting them 'bleed' outside of your network

    Either way, for the past 3 weeks, no more V87 errors.

    With all due respect to you, I feel that some of the remarks posted here were nothing more than abuse. Yes, there have been some helpful remarks, actually the majority of remarks and comments have been, but some, in particular two, were not, and were very personal. I am a very experienced Network Engineer, and a very experienced Tivo owner. I've had six of them. My comments, up until the remark you referenced, were only about Tivo and some of it's failures, which should be fair comment in this forum.

    But when it becomes personal, yes, I will fight back.

    I too have been in the network and computer support business since 1985. One thing I've learned about these forums is that despite my computer technical background, I have to be thick skinned to get what I need here. Reading posts doesn't convey the same way as if you were face to face and obviously it's much easier to to mis-read intentions.

    The hardest thing for me to recognize is that while I am a really good computer support analyst and respectable network analyst, I might suck at the cable TV and "all things" MOCA infrastructure. Some things that I think should be 'logical' aren't. I don't always understand why some things work and others don't.
    I'm now always ready to accept that some (all?) blame of a particular problem is really on my end (cabling, splitters, etc.) until proven differently.

    Look, reasonable, and reasoned comments like yours are fine. But really nothing short of getting a coax cable tester, and going through the house connection by connection, there's no point. And I might still do that. I used to use them with the old Ethernet coax, but nobody I know has one anymore, but I guess I could buy one, I suppose.

    As I mentioned earlier, there's no obvious splitters or amplifiers, unless they're in the attic, which is covered by insulation. I have not installed any splitters or amplifiers.

    Is it worth it to rip through the attic disturbing all of the insulation searching for a potential problem? Is it worth to run Ethernet cable just to support the Mini? Well, for me no, it's not.

    Bottom line is that Tivo got me again with the Mini. Like the early Premieres and the Slide Remote, the Mini is, another example of a product that kind of works.

    The Mini cost me about $250, and I'm not ripping up my attic or running Ethernet cable just to support it. I'll sell it on E-Bay and take the loss.

    If you don't have a splitter somewhere in the house that concatenates all of the lines, then each room would be on its own isolated segment. Your Mini would have never worked. You would also need a seperate cable company demarc for each room.

    Would TiVo not RMA it for you?

    Yes, I think they will, but I'm not keeping it. Once I get it back, I'll just sell it with the lifetime sub, and take my losses.

    I already bought an old Premiere, which I'll use for now.....I used to have two Premiere's, with cable cards, etc and I sold them both. Wish I hadn't.

    I've said this before... but guys, it's always worth it to run ethernet. Always. Do it. seriously, suck it up and run the ethernet. Not just for your mini... to make your life better for all future technologies too.

    I but a new device, and I don't have to deal with wireless signal, wireless security, blah blah blah. I just plug it in and it works.

    +1, I've been converting all my phone outlets in my house to Ethernet and all is good in my electronics world (TV's, computers, Tivo's, Roku's, etc). My Mini has been flawless since day 1 and streams from 3 different Tivo's (two of them 2 tuner Premiers) with zero glitches so I'm convinced that the mini is well designed for what it does.

    I custom built my home in the late 90s but I did run RG6 quad shield from one point in the cellar to each cable outlet, so MoCA was easy for me, but I had a friend that required outside cable splitters to be removed and the cable run directly into the cellar to get his system to run using MoCA, a real pain.

    Surely there is at least one central splitter somewhere near where the cable service enters the house. You mentioned installing a POE filter. What is the POE filter connected to, if not a splitter? The POE filter should be installed on the input side of the central splitter. If you don't know whether it is or not, it could be hindering more than helping.

    Once you find it, if there aren't enough outputs at the central splitter to feed all TV outlets, then you know there are other splitters someplace else too.

    Some homes/Apt. were built with taps for each cable outlet, saved time and cable but I don't know how such taps would work with MoCA. The POE filter should never be used until your MoCA system is up and running well, then, at you option, install the filter at cable input. I am sure people are not sitting on you cable hoping to lock onto your MoCA signal the second you turn it on. You won't find 1 in a thousand people who even knows what a MoCA signal is.

    I'm getting ready to put my house on the market, and I know the first thing I will have to do, before I even move in, is run Cat5e or Cat6 to every bedroom and living space in the house.... I'm just ready for it. I know my wife is going to want to repaint every room anyways.... so, time to break out the drill, jig saw and fish tape and start running the cables! Patching drywall anymore is second nature with all the work I've had to do on my current house.

    The one thing I haven't had to do in my current house is run ACROSS the joists... just pure luck with how the house is laid out (crawl space and some unfinished attic space), i could always run WITH them. I know this is going to come up at some point in the new house and I'll have to figure out a good way to do it.
