Use the link below to measure the packet loss from the Hub and your computer to the public internet.

Packet loss that greatly exceeds the figures for the Computer when streaming (to Twitch etc) are not occurring on your connection from home to the public internet.

Once the test begins click on: Run full test to see all the stats ( Latency  / Jitter / Packet Loss / Upstream rate )

Cant run samknows as I have the hub in modem mode.
However the BQM attached is pretty horrid with constant packet loss and the upload is completely unstable.

Try checking with Area faults on 0800 561 0061 or if you have a VM landline 150 as small local faults are not listed on the VM status page.

Post the power levels, Pre and PostRS errors and network log from the Hub.

What Hub are you using and is your connection wired or wifi ?

Once done we can comment.

"Dropping anywhere between 5-10% packets" - do share how that is measured.

Try ...

Once the test begins click on: Run full test to see packet loss / jitter / latency / upstream speeds


Measured with PSPing and when stream running last night I was seeing significant frame / packet drops.

Hi @ThatAngryBrit

Welcome back to the community 

Sorry to hear you're having service issues. I have checked the systems at my side and can see that there is currently an area outage raised. The area outage is due to SNR (Signal noise ratio) causing interruptions and disruption to the signals in the area. You might find that your Virgin Fibre, Voice and Virgin TV services are intermittent, with the picture freezing or disappearing now and then. We are sorry and our engineers are working hard to resolve this for you.

The estimate fix time for this is currently 24th April 2023 at 11:10,  once the outage looks closed/fixed, please reboot your equipment and let us know if you have any further issues. 

Here to help 🙂
