Upstream power levels quite high:

The HUB reports them a decimal out so are actually what I've posted above.
Downstream levels on some of the channels are quite low (-6 to +10 is in spec).
Lots of errors on some of your downstream channels.
Could you create a BQM (Broadband Quality Monitor) here and post the live link?
This will confirm the quality of your line.
