Mini's can't connect with Roamio... is this something I just live with?

    Since day 1 (Dec 2013) I've always had an issue, usually 2-4 times a week, when both of my two mini's "can't connect with Living Room..." (Roamio) (not necessarily at the same time either).
    Over the years, I've researched many "solutions" via this forum, TIVO's website, other online resources, contacted TIVO directly, used Moca off and on, switched back to ethernet, replaced one of the Mini's, had brand new coax installed... and the list goes on. Sometimes I go a couple of weeks or so without this issue but, on average, over the years, it always re-surfaces even if it stops for a few weeks.
    The temporary solution is to reboot the mini and it seems to always then be able to communicate with the Roamio (until next time).
    I'm not asking for any suggestions because I feel pretty certain that over the past 5 years I've dug deep enough to try so many things (and repeatedly) that I'm just tired of trying.
    So, I'm wondering if anyone else out there is in a similar situation and is just living with it, like I am, until the next best thing comes out.

    Per your previous thread... moca errors on mini's ... you indicated years of working connectivity until mid-2017.

    And I hear/understand that you're not looking for suggestions, but... seeing that your signature states "Time-Warner Cable-Austin" and "TA: Cisco STA1520," I have to ask:
    • How are the TA & Roamio each connected via coax to their wall outlet?

    • And do you have a MoCA filter installed on the TA's input port (to protect the TA from MoCA signals, and MoCA from the TA)?

    I have tried it multiple ways when on moca with a splitter at the source (one to Tivo, other to TA) and I've tried a splitter at the Tivo and TA (with splitters that meet MOCA specs). Right now I've switched back on ethernet for the past 3-4 months. When using MOCA in past I had a filter at the initial input point where SPectrums' powered splitter was in the attic (so signal doesn't get out) and I've had one on the TA input. When I was using MOCA I researched and tried various connections and documented results at that time.
    Now, over the years there have been other issues as well that mostly got resolved with new cable runs, or software updates, etc., but this one issue has persisted thoughout.

    A whole post of suggestions/comments you can skip, at your choosing ...

    Either:
    • Many recommend using static IPs for TiVo boxes. I've been using static-leased IPs for our boxes from the beginning, so can't speak to an experience using all DHCP addresses.
    Ethernet:
    • If you're experiencing periodic disconnects, you may want to look into the IGMP Snooping (link) or "green" switch issue that some have encountered. (No clue what network gear you have ... router, switches ... so can't be more specific.)
    MoCA:
    • So, yeah, the DVR must NOT be connected via the TA's RF/STB Out pass-through port if/when the DVR is using MoCA.
    • The MoCA filter recommended for the TA's input is distinct from the MoCA filter required at the cable point-of-entry. You'd have two total MoCA filters installed, one at the PoE and one on the TA's coax input port. (link) It might even be worthwhile having a prophylactic MoCA filter on the modem's input port, as well.
    • What is the brand/model of the provider-installed amplifier? This comment... "When using MOCA in past I had a filter at the initial input point where SPectrums' powered splitter was in the attic (so signal doesn't get out)" ... indicating the amp didn't have a built-in "PoE" MoCA filter, makes me think that the amp wasn't MoCA-friendly, and could be replaced with a model that is. (similar)
    • "with splitters that meet MOCA specs" :: I prefer Holland's GHS-PRO-M series or Verizon's MoCA 2.0-rated splitters.
    • MoCA stats (TX/RX PHY rates and power estimates) reported by MoCA-connected TiVo boxes are useful for gauging the MoCA network's performance.
    • I believe TiVo introduced some MoCA hiccups in a recent update, but I believe those were ironed-out.

    p.s. Yeah, frequent flyer, it seems...

    krkaufman, appreciate the effort...
    I have used static IP's for all Tivo equipment, always have.
    I have also disabled IGMP on router, always have done that too.
    Since I'm not using MOCA I didn't answer those because I prefer use ethernet. I only used MOCA thinking it would help the problem but it made no difference.
    I even moved all of the TIVO ethernet connections directly to my router instead of using a switch.
    I also replaced ethernet cables with known (higher quality).
    If you really want to know the splitter info/POE info I can dig it up but hope to not use MOCA again.

    No worries Re: MoCA; it just wasn't clear from the OP or history what the current configuration was.

    I see you've replaced one of the Mini's, at some point, but has the same Roamio box always been a part of the equation?

    Yes, the Roamio has been a constant.

    I've been rock solid with ethernet since the beginning, I have one mini, 2 bolts and a roamio (previously had a premier too).

    I tried using MoCA once just really to see "if it worked" and I had no issues with it either, I went back to ethernet for two reasons, 1) I'm more familiar with it 2) I already had ethernet jacks everywhere I wanted a TiVO

    Granted I probably have what I'd call an "uncommon home implementation" for my network, it is more like what you'd find at a business. I have all my ethernet home run starting with an RJ-45 jack on the wall, to the basement to a patch panel, from the patch panel I connect to a 48 port switch (cisco) switch. Every run was certified to meet Cat5e performance (helps to be in the business). My CoAX, although not tested, was similarly run, with a female F connector mounted to a plate on the wall to a single splitter in the basement using RG-6, I have no unused CoAX connections on my splitter (unconnected CoAX ports/runs introduce noise)

    One thing you really have to keep in mind is that the Mini requires close to 20Mb/s when streaming live TV and if you have a bad ethernet run (bad cable, port, etc) you will find it difficult to get a reliable 20Mb/s out of a gigabit port.

    Many people here swear that TiVO's don't play nice with DHCP, I have also used DHCP from day 1 on all my devices, I have a 3 1/2 day lease time and also have never had an issue.

    Sorry you are having issues, I truly believe there are 2 very common issues with most home environments
    1) poor cabling with both ethernet and CoAX (eg bend radius exceeded, improper cable termination etc)
    2) low quality consumer grade ethernet switches.

    TimeLord, thanks for the response. While I can't claim any certification on the ethernet cabling I can say this is new cable going to 2 mini's and plus this same thing would happen on coax when I'd try MOCA for a few months. The issues aren't related to streaming, I mean they could be, but when I typically notice the problem when I'm using the Tivo menu to watch recorded tv from one of the mini's. In the case of the mini's and Roamio, I have always had them directly connected to my Netgear router to minimize potential switch issues. Odd, now that I think of it, it's been a week since I've had to reboot a mini, but next week I may have to reboot one/both 2-3 times. I wish this issue only happened on either ethernet or MOCA, one or the other, so I could just stick with one that works all the time.
