Downstream power levels are high, but just within spec and upstream levels are borderline on one channel and too high on the others.
This will need a tech to visit to sort out the power levels. You can call VM and try to book a visit or wait for the VM staff to get to this thread and they can help you book a visit.

Apologies for your poor connection but both SCA1972 and griffin are correct. Those downstream power levels are borderline high, along with one of the upstreams. The 3 other upstreams are too high.
I've checked and there was a cluster of errors on the upstream network segment 2 days ago though it has been clear since then. I'd like to arrange an engineer appointment for you, so please reply to my PM (purple envelope icon, top right of page) when you can and we'll get an appointment scheduled in for you
