    I am experiencing, as of the past couple of days, the same "network lost" error with a Mini running 20.6.3.RC15 when watching live TV -- tried the fix above with my Premiere as host and still have the problem with v87 error. Setup had been fine for more than a year.

    What I have tried, no solution yet, must be a bug, everyone please open a case with TIVO so they will know this needs fixed first. Other wise they will just think one or two have the issue Link is below

    1. I have tried this fix also, this is not a fix to the issue, it simply tries to reset the MOCA setup.

    2. Both of my Minis are now on RC15, no change.

    Issue seems to be worse when you put one of the Minis in Standby or if it times out form use and goes to the Push the Tivo button to watch TV

    3. Other says change the MOCA channel to 27 to avoid interference and that fixed some PROBLEM is on RC15 on the BOLT you can no longer change channels so this is no fix. Mine is on MOCA channel 23

    4. My Moca Speed is 280 MPS my TX is -27 and -26 is that too high or low?
    I tried 3 sets of Splitters including Moca Certified splitters and several POE filters from different brands.

    5. OPEN ITEM- Only think left I can think of is all no COAX buying 3 GHZ rated COAX but that will be hard to run through walls.

    6. Temp work around- I did try Ethernet to narrow it down, did not have the issue but Ethernet is not possible in the rooms I need the MINI

    7. Tried Static IPs on both MINIs , did not help

    EVERYONE Please open a Case with TIVO. Here is the link to the form.

    I have recently started having the same problem.

    My set up is completely gig Ethernet. No MOCA. I am seeing it on 2 Mini's Only on live TV, no issue with recordings.

    I am leaning toward bug also, as it has only been happening for the last month or so and nothing has changed in my network.

    Does anyone know exactly where we can find the definition of the error V87?
    If it's a connection to Tivo hosted servers via the Internet, that may have been my problem.

    I ended up replacing ethernet cables, and all network gear in my home LAN, because I'm a network professional, I now have entry level enterprise gear connecting all of this together.

    When that had no effect, I started looking at my Xfinity/Comcast ISP. I did find issues there, I started noticing variable packet loss, that never went away completely. Several service calls and a service-trunk-roll to my home, and the comcast tech agreed that there was a neighborhood network issue and raised a service ticket. This took weeks to resolve, and when they were done, I still had low level packet loss. My personal cable modem was no longer supported, so I upgraded to a new modem on the supported list, and the low level packet loss issue was gone. The modem replacement was 2017/01/20 approximately.

    With so many things going on (plus some personal events that distracted me from this issue), I didn't notice right away when the mini disconnects stopped occurring. I don't believe I've seen this occur since the modem was replaced... I didn't remember this forum post until today, so I'm back here to check in.

    Comcast/Xfinity has dropped many modems from the supported list. In the fall of 2016, I called-in and downgraded my service to Performance Internet (25 down/5 up), when they had automatically upgraded my service to the next tier. The faster tier was actually much worse than Performance, many intermittent issues and flaky speed tests... That should have tipped me off, that there were issues with my modem and the way it was performing on the Comcast network, but it didn't register.

    If I have some time, I may try and block outbound network traffic out of my network and see if I can trigger error V87 and confirm that this is the root cause or not.

    If anyone has any better feedback on this matter, I'd love to hear it.

    I believe V87 signifies a disconnect (insufficient bandwidth or response) between the Mini and its host DVR, and the Internet connection shouldn't have an effect. It's possible that your V87 errors went away if your devices updated to 20.7.1, which supposedly included some fixes related to Mini/host communication.
