High latency errors on my network (Superhub in modem mode) - Logs attached

I have my Superhub in Modem mode and have a UniFi setup at home.
Speed 1Gb up / 100Mb down.
 
 
Getting an error every night:
"Primary internet is experiencing high latency. Please restart the modem or contact the ISP if this persists."
 
 
Anyone see any issues in the logs? (obscured the MAC's)

    The details of the signal levels and error counts from the Upstream & Downstream tabs
    would be much more informative to see.

      I just set up BQM, I had to add firewall rule to allow pings so I don't have a lot of data yet (modem mode).

      The symbol rate sets the width of the channel. It may be an attempt by VM to work around some noise issue.

        Should I contact them about it?

    They may know about it, but personally, I would be interested in knowing, if they are working on it. It is a ~20% drop in upstream capacity. Have you noticed, if the QAM levels tend to drop? That will reduce the capacity further. Reduced capacity just makes the matter worse, if there is high pressure on the upstream is the busy hours 🙂
