Yes, they look fine.  Some PostRS errors, but you may not have rebooted the Hub recently?  Ideally these should be zero.

Do you have a problem with your Broadband?

[sidefx]

Hi thanks for the reply and I did a reboot they are now zero. I did have virgin media out today because my internet was intermittent thinking they'd fixed the issue and not long after they went internet dropped out for 5 mins. It's all ok now but I'll just have to wait and see.  I hope the reboot helps and thanks again.

I do have pre rs errors though anything I should be worried about?

[sophist]

Pre rs errors are nothing to worry about… just the post.

Those power levels are in spec.  -6 to +10.  However there is noise on your circuit i.e. PostRS errors.  Check all connections are finger tight, from the Hub back to the outside as loose connections can cause noise ingress.

Other than this, nothing you can do except phone VM and request an engineer to fix the circuit.
