    What are all the network appliances involved? Switches, router, MoCA adapter, etc...

    Not knowing anything else about your setup, my money would be on the need for a "PoE" MoCA filter.

    Aside from gradual degradation of components, your MoCA setup may have been borderline and some small tweak pushed it over the edge. A "PoE" MoCA filter doesn't just block MoCA signals from exiting the home; it also efficiently reflects MoCA signals back onto the coax plant, strengthening the MoCA signals.

    Also, if some other home in the neighborhood has MoCA active and also failed to install a "PoE" MoCA filter, the MoCA networks could be conflicting.

    Arris Tm722g Cable Modem connected to Apple Time Capsule for WiFi, MoCa adapter is the Bolt. Pretty simple setup.

    Oh, before the Comcast tech arrives, you may want to see if you can check/report your MoCA stats -- assuming you're in the window when MoCA is working -- from a connected Mini (not sure if the BOLT has had its Network Status screen fixed).

    See here for how to check MoCA stats.

    The pre-"PoE" MoCA filter stats might provide insight on being on the edge of the performance cliff, and would, at a minimum, provide for an interesting comparison for after the "PoE" MoCA filter has been installed.

    Thanks so much for this. I'll document the stats tonight. I was expecting that calling Tivo support would have them look at something like this (I didn't know these stats existed), but it was never suggested by the rep to look at these to see the MoCa quality.

    So the pre numbers. First off, I have numbers for two different nodes, is that normal? One PHY rate is 120M, the other was 273M.

    Installation of the PoE fixed my issues. Thanks to @krkaufman, a check of my MoCa numbers showed that there was also a weaker network showing up, probably causing interference. Now with the filter, my Mini only sees one network and its PHY rate increased from 273M to 282M.

    woot, good to hear!

    And good catch re: the additional MoCA node. My first read of that was, yes, you would always have at least 2 nodes total in a MoCA network, but I see now that you may have been seeing 2 "peer nodes" in your MoCA network stats, meaning the "number of nodes" would have been reported as 3 -- when you only had 2 TiVo devices.

    Looks like we can add your tale to the list of examples where a "PoE" MoCA filter was critical.

    Sorry I wasn't clearer. Yes, my Mini reported 3 nodes and 2 peer nodes. Now with PoE, it is 2 nodes and 1 peer node.

    Going back to your earlier comment, yeah, TiVo Support should be aware of the Network Status info and using it to diagnose MoCA issues, both by reviewing the MoCA signal values and, as you've demonstrated, verifying a one-to-one relationship between a customer's devices and MoCA nodes.

    Did anyone ever reply? I am having similar issues. OR, did you fix it?!

    I just started getting the V87 error a few days ago. I have FIOS and use a MoCA network with one Roamio and 2 Minis. One of the Minis just started having the V87 error about every 10 minutes, making the service unusable. This is a configuration that had been working for a couple of years with no problems. HOWEVER, we had moved one of the Minis to a different room. This Mini had an Xbox connected to the Ethernet port, and like I said, had been working for a couple of years. But the problem did turn out to be the Xbox. If I disconnected it, the V87 error stopped. If I connected the Xbox again (to any Mini or the Roamio), the error started again. Maybe an issue with dynamic IP addresses? Not sure, but the router did not show any duplicates.

    Anyway, I was able to resolve the problem by connecting the Xbox directly to the router using an Ethernet cable instead of connecting the Xbox to a TiVo device. Now Xbox can remain connected (to the router) and no more V87 errors on TiVo units.

    FYI, I don't have a POE filter on my network. I asked 2 different TiVo support reps whether I need one with FIOS and haven't received a satisfactory error. From what I've read I don't think I need a POE filter because the FIOS ONT will act like a POE filter, but just wondering if anyone knows for sure?

    A "PoE" MoCA filter isn't required for FiOS to secure the MoCA network, since the MoCA signals can't travel beyond the ONT; however, a MoCA filter installed on the input of the first splitter encountered by the coax coming from the ONT would improve the performance of the MoCA network.

    As for the XBOX, connecting it to a Mini's Ethernet port would serve no purpose, since a Mini can't bridge between MoCA and Ethernet; it's interesting that doing so may create network issues, though. When connected via the Mini's Ethernet port, I expect the XBOX was still communicating via wireless.

    Curiously, others have also reported connecting an XBOX via the Ethernet port of a MoCA client TiVo DVR has created network issues.

    Thanks for the feedback, krkaufman. The info about the PoE filter makes sense, I will pick one up to improve MoCA performance. I'm actually a little stumped by your comment about the Ethernet port on the Mini. It makes sense as well, however, we do NOT have Xbox configured with a wireless connection - if we disconnected the Xbox from the Mini and did not have it connected to anything via the Ethernet port, we had no network connection for the Xbox. I don't know why it has a network connection when connected to the Mini if Ethernet cannot be supported over MoCA, but it does (and did for a couple of years without interfering with TiVo). Regardless, connecting the Xbox directly to the router resolved the issue we just started having recently, and has been working perfectly now for the past couple of days. Thanks again for the info.

    Wish I'd heard you were doing this back when it worked; would have been interesting to test.

    I had constant issues w/ my Fios router and my Mini (losing connection), which was connected to a Roamio via ethernet. For other reasons I switched to a newer Linksys router (around $100) and was still having issues. I tinkered around w/ the settings of the Linksys and set-up a "DMZ" for the IP addresses of the Mini and the Roamio. This allows them to communicate freely around the firewall (based on my limited understanding). That was months ago and we have had no issues since. Just wanted to pass along since it drove me, and my wife, crazy for a very long time.

    For the Fios router I turned off it's wireless capabilities , but let it handle the IP address distribution (the Roamio and Mini are on static IP's). Also, the Linksys has a phone app which lets you reboot the router without having to walk upstairs. A reboot every few weeks does wonders as well.

    My TiVo system appears to be skipping during TV broadcast, going on maybe two weeks now. The broadcast begins to "studder" constantly, eventually dropping-out completely. And this behavior seems to appear usually late in the day (around 06:00pm and later). However during the early day, the broadcast exhibit's mostly "normal" behavior. Naturally, I have bounced (power re-set) router, modem, and main TiVo box on several occasions, but skipping eventually returns. Although on one occasion I bounced the NetGear PowerLine Adapter (for the living room system) and things cleared, but skipping behavior returned the next day.

    On a few occasions, while troubleshooting, I get a TiVo message (paraphrasing): "Network connection too slow, v69, etc.,..". At this point I can only think it must be my router? Or possibly a network switch? (I'm using like three throughout my system)

    I'm using (in Media Room):
    TiVo Roamio Plus-Pro DVR
    Cisco STA1520 Tuning Adapter
    NetGear GS605v4 Network Switch
    NetGear PLP1200 Powerline 1200 Adapter (passes etherNet throughout house, from Media Room)
    Arris TM-1602 Modem
    NetGear AC1900 Smart WiFi Router

    I'm using (in living room):
    TiVo Mini
    NetGear GS605v4 Network Switch
    NetGear PL1000 Powerline 1000 Adapter (receives etherNet from Media Room)

    Also, I'm using etherNet connection for TiVo (obviously), not MoCa. I originally had MoCa set-up, but Spectrum cable technician purposely un-did the separate cable-drop for the MoCa.

    As usual, everything has been working okay for quite a while. This behavior, coincidentally, appeared following record summer heat spell here in Southern California (temperatures up to 116 and 118 degrees), so I wonder? My Media Room becomes noticeably warmer later in the day, I'll have to monitor more closely.

    You’re not using Ethernet, you’re using Powerline. MoCA would seem to be the better way to go.

    You’d also want to look into the IGMP Snooping setting of your Netgear gear. (Though that usually exhibits as an access issue, rather than speed.)

    What “separate cable drop” and what rationalization did he/she supply?
