The downstream power and SNR data looks OK, although the reported zero errors are down to a firmware bug, not because there are none.
The BQM shows continuing low level packet loss, which is usually a noise issue, and should be fixable, the latency profile looks unfortunately like there's network congestion. The two are probably separate problems. Check the BQM IP address is the one you have at the moment - normally they are very "sticky" and might not change for years, but mine has changed about three times this year (and that's not counting times the IP address has changed because I've been switching between modem and router mode on the hub).
You can post up the remaining status data for Upstream and for the Network log, which may or may not show more evidence, but fixing the noise fault will probably need a technician visit. As for the apparent congestion, do a search of the forum on the term "over-utilisation", and see what comes up (Parental advisory: It's not good news).
