Far too many uncorrected (post-RS) errors on lower frequency downstream channels, which would explain the poor speeds. Given the clustering around 130-180 MHz that's probably noise ingress on a faulty connector, cable, or could be a VM plant fault that's creating noise. It's unlikely to be a faulty hub. Low error counts on higher channels indicate the hub's recently been rebooted, so other than checking the coaxial cable connections to make sure they're properly made and securing nuts are finger tight there's nothing you can do. I'll flag this for the staff to advise.

Thanks Andrew. I used the automated test tool via myVM and it said and engineer visit is required.
Hopefully they will find the problem.

Hi Chaosuk,
Thanks for your post and apologies to see you are having some issues with your broadband services.
Looking at your account I can see that since posting you have already booked an engineer visit. To view this please sign in to My Virgin Media here: My VM
Please do pop back here to let us know how the visit goes and if things are resolved 🙂
Thanks,

Sorted! The engineer came and performed a factory reset on the Hub 3 and it cleared all the errors and speed is back to normal.
I rebooted the hub a few times but never thought to factory reset it.
We had quite a few intermittent power problems in our area just prior to my speed issues so maybe that had an impact.

Hi @Chaosuk,
Thanks for popping back with an update. Glad to hear the engineer was able to resolve things for you.
Don't hesitate to give us a shout should you have any further issues.

Keep your eye on your hub stats - if the postRS errors start to climb again - pop back on here - that is a sign that something is still wrong!
