Looks like an upstream noise issue, judging by the varied modulation on upstream channels and large T3 timeout count on upstream channel 2. That would also explain the high downstream post-RS (uncorrected) error counts. That'll likely need a technician visit, I'll flag your post for forum staff to advise, and they can arrange a technician visit if needed.

Also the upstream power levels are too high, and the modulation should all be 64qam.
You should factory reset your hub so that Pre and Post RS errors are set back to zero.
Keep the hub switched on and disconnect any ethernet connections, then push the reset button firmly with a paperclip or something similair. keep it pressed in for around a minute.
Wait around 10 minutes and it should revert to factory settings. You can now reconnect the ethernet cables.
If you previously changed your router password it won't work and you will have to use the one printed on the sticker on the router. You can always change it again by going into the settings
You can also click check service status at the top of this page after performing the reset and run a fault test.
It might be worthwhile checking your cables are all snug and tight with no kinks in them.
You could also set up a BQM monitor atthinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you can post the link straight away.

Thanks for getting in touch and welcome to the Community Forum! I'm sorry to hear about the problems that you've been having.
I've been able to locate your account using your Forum details, and it looks like there might be an issue with your coax (white) cable. Could you please check that the coax cable is securely connected to your Hub, any splitters, and to the wall socket?
Please let me know if these issues persist once this has been checked, and I'll be more than happy to take a closer look.
If the that the coax cables is connected securely to the Virgin Media equipment, any splitters (standard and powered) and to the wall socket. Could
Yes the white cable is securly attached to the wall socket and secure into the back of the hub. I've checked this a few times over the past weeks assuming there could just be a loose cable however the issue does not change.
