OK, well at least 2 of your downstream channels are below the minimum -6 dBmV and a few more are very close to going out of range.
Did the installer leave an attenuator in line between the VM cable and the back of the modem? If so try removing it to boost your power levels. If not, then you will need an engineer visit because the next remedy is to put your cable onto a higher power tapping point in the street cabinet.
Sadly I think the BB "help" line call centre just read off a script and have even less of an idea than I do.
I rang and talked to the UK call centre to confirm that I am out of contract, so that is one thing less to worry about.
It is quite annoying to only recently find out that the sparkly new Hub 3 I received turns out to be a bit of lemon....now when folk ask on the forums I follow, which TV/BB provider to choose, my answer will have to change to..." Virgin, unless you like gaming, in which case go with someone else."

Thanks....so I rang Virgin broadband and related the issues.
They said they had sorted the low power while I waited and it was all fine...except of course when I check they are the same levels as before (can't see an attenuator anywhere to remove.)
Apparently there is a problem with high utilisation in my area...which of course is hard to believe given the BQM graph is fairly consistent regardless of time of day
I asked for an older type Hub but was denied.
Anyway they said it will all be fixed by the 23 Feb....well I hope so, I could really do without the aggro of choosing a different BB (and probs TV) supplier.
Thanks again for taking the time to reply.
They can't change power levels over the phone, an engineer has to visit as it involves some work at the street cabinet. VM customer service on the phone is awful, but hopefully a member of the forum team will respond within a few days and arrange an engineer for you. The offshore call centre usually just change your WiFi channel (often making things worse, as they have no idea what channels are clearest in your home) and then say everything will be fine.
The graph looks normal for the Hub 3 with no sign of over utilisation.
