Thanks for your post and for coming back to us with an update on things.
I have checked things this morning and can see the area fault has since been resolved so this is no longer affecting you.
It looks as though there are some errors logged and the power levels need some adjusting. I would like to arrange for an engineer to come to take a look at this for you.
I just need to confirm the address to ensure we are booking the visit on the correct account. I have sent you a private message regarding this. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
I have booked you in for the next available appointment. We cannot confirm the appointment time slot, so to view this please sign in to My Virgin Media here: My VM Just go to My Account > Track your orders.
If the appointment is unsuitable or if anyone living at your property has tested positive for Coronavirus, has been asked to self-isolate or has flu-like symptoms then please reschedule the appointment on the same link.
The engineer came and added an attenuator to fix the power levels. I've checked a few times and power levels seem to stay within spec. For the most part, the big slowdowns have been fixed, however there are still occasional slowdowns (recently to between 10Mbps and 100Mbps).
This test was taken today at 4pm

The power levels are within spec for both upstream and downstream. The speedtest was performed on the Edgerouter, connected directly to the VM hub in modem mode.
Maybe the power levels were only part of the problem, but there is a fault elsewhere?
Thanks for your update and apologies that you are having continued issues.
Taking a look at the account all is looking good. Can you please try re-running the speedtest connecting the Hub directly to the Laptop or PC? This will allow us to rule out a third party router issue. Make sure you turn the Hub off, disconnect the router and connect to the PC or Laptop before turning the hub back on.
You'll also need to ensure the network card on the OC or Laptop is 1GB and that the ethernet cable is cat 6e minimum.
I'm running the speedtests on a Ubiquity EdgeRouter X. Although this device can act like a router, it is actually just a Linux computer running Debian. I'm running commands on it directly though ssh. It is connected directly to the VM hub through a required POE injector.
If the VM hub is capable of running a speed test I am open to try that, but otherwise I'm as close to the network entrypoint as possible.
I was confused for a bit about your next statement - I assume you mean ensure it supports gigabit? 😅 The ERX does indeed support up to 1Gbps. I'm currently using cat5e cable, which should support 1000BASE-T. If there's a known issue with this protocol and VM routers I'm happy to try a higher category cable, although I've never had an issue with gigabit speeds and cat5e before.
If it's any help I've been keeping an eye on my BQM, and the slowdowns seem to correspond with spikes on the graph.
Latency does seem to be the biggest issue - I measure download speed at about 100mbps as mentioned, however it can often take several seconds to load any webpage during this time as it seems to be taking a long time to connect to each domain.
Any other tips I can try? Maybe the VM hub is faulty? Is it possible to perform speed tests or allow BQM pings from the VM router in modem mode, so I can further rule out other equipment?
