Network log doesn't indicate anything unusual, BQM looks like something is up, and I think the range of downstream power levels is too high, from 3.5 dBmV to 8.1 dBmV, though that's my view, VM are reticent on the permissible range. The upstream looks as though there's something up - it shouldn't have anything like the number of T3 timeouts that are recorded. I'll flag this for forum staff to advise, but be aware that they may wish to query the hub's status, but can only do that if the hub is in router mode. And as soon as you swap modes, the hub will reboot, all of those recorded errors will be reset (and your BQM will stop recording because your IP address will change), and when renegotiating channels the power levels may even out. However, if there's any "looks good from our side" response a polite challenge would be appropriate as to the cause of the latency peaks and the upstream timeouts, and why the hub was letting the downstream power levels spread so far.
See what they advise and we'll take it from there.
