    Today, some channels weren't working. I got the "searching for signal" error.

    It seemed like channels 718 - 725, at least. Higher channels worked.

    I called my cable company. They couldn't resolve it with a power cycle, so they sent the case to the escalation team. They claimed the escalation team was 24 hours, and would call me back today.

    I doubt it.

    I have a feeling that they'll forget about me, and I'll have to call them back tomorrow.

    I think they'll also try to blame my equipment, since it's not theirs (Tivo).

    They tried to blame my cable card, by saying it was old.

    I haven't had any equipment changes in months, and everything worked yesterday.

    I did set up a MoCA network in September, though. I changed one splitter from 900Hz, to 2050 Mhz.

    The one directly connected to the MoCA filter is less, though.

    Like I said though, I hadn't had any issues until today.

    My signal strength for the tuners is at 81%. I wonder why it's so low.

    I changed one of the coax cables. It raised it to 88%.

    Cable company still hasn't called me back.

    Still, the next time I go to the hardware store, I might buy another splitter and replace the one directly connected to the MoCA filter.

    All channels work now.

    Who is your cableCo and location? You might need a tuning adapter, the channels may be Switched Digital Video.

    I wish this forum had a pop-up message every time you start a new thread, saying something like:
    "If you are reporting a problem receiving cable TV channels, please include your location and service provider in your post."

    A Premiere doesn't have the same AGC circuit as a Roamio or Bolt. My two-tuner Premiere is happy at 78% with a 36dB SNR.

    Good luck with that. Location should be a mandatory entry during registration. Plus you know all TiVo units are the same.

    Good point. Pop-up message should also request TiVo model!

    If your Premiere was happy at 78% for all channels, why was mine unhappy at 80% for some channels?

    Also, it's a bit disappointing that the signal level dropped so much. When I put in the MoCA filter, and replaced one of the splitters, in October, it was at 91-92%. Prior to replacing the splitter, it had been at 87-88%.

    Then yesterday, it dropped it 80%, before I replaced one of the coax cables from the splitter to the Tivo. Then it went back to 88%. Which is better, but not as good as October.

    Tivo Premiere XL4, Xfinity (Comcast), northern California. All channels work again (some weren't working when I created this thread) after I replaced one of the coax cables.

    I've had the same service for years, no changes there. I've had HD service the entire time.

    What is the SNR? I have zero errors on my cable feed.

    Depending on the tuner, 35 - 36 dB. This is after replacing the coax last night.

    I also just noticed that while 3 turners are at 88% signal strength, one is at 92%.
