I can accept that everything may be in spec, but the network log is quite definitive and shows synch failures and downstream channel loss faults at 11:05, repeatedly around 11:30, then again after 13:20, then again at 14:34, and again at around 17:50. Other than producing a spikey picture, I'm not sure how a BQM helps.
@whosagooner Have you physically checked all VM coax connections in the house? Undo them, wipe them, and redo them with the nuts finger tight, remembering that the hub takes about 7 minutes to come back on line after the connection is interrupted. You can also try a pinhole reset of the hub. If you're feeling ambitious you can do the same coax connection check in the brown plastic omnibox outside usually found outside on your wall. Other than those, nothing else you can do, and if the problem continues then it's either a faulty hub (rare, but does occur), noise on the line (common), or a network equipment fault (less common). All of those last three require VM to investigate and fix.
I assume the hub's main LED is showing white (other than possibly looking like a reboot sequence when trouble occurs)?
