You are missing a downstream channel and your downstream SNR ranges from poor to marginal and is the cause of the high RS errors you are seeing.
Your logs are full as the same entry is repeating, might be worth rebooting the hub.
You will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response.
Thank you for highlighting the problem. Is it possible to get a forum team member to look here quicker? As the account holder (talking on her behalf) has forgotton the password/pin she set up over the phone. However she has an account on myvirginmedia that can be freely used.
Thank you, I haven't had an engineer personally visit me (unless you mean they did an area fix). My internet has been better at times but it's still widely inconsistent... Right now for instance I have a 1.44 mbps download, which is still similar to what i am getting with my phone. Yesterday it was good throughout the day ranging from 10mbps-50mbps, so I was able to do some things with minimal issues but at night it hovered around 2mbps.
