Intermittent connection drops – upstream/downstream power issue

I've had this several times over the years, occasionally it gets worse for a day or two at a time then stabilises.
My hub is repeatedly rebooting due to upstream signal loss. The downstream power levels are hitting +8 dBmV, and my upstream power is around 40 dBmV with repeated T3 timeouts and sync timing failures. This indicates noise or a power-level issue on the coax line. I need a technician to check the external line, connectors, splitter, and cabinet.

    At first glance, the reboots don't look to be caused by a bad signal. How is the hub powered - through an UPS? Has the hub been replaced at some point during this issue?

      The hub is just plugged straight into the outlet in the wall. Have tried a couple of different outlets, doesn't seem to affect this issue.
      Hub has never been replaced - could be hardware?
