BQM analysis?

[Jsquires1990]

Hi anybody able to say whether these BQM snapshots are normal and to be expected, I recently got Sky Glass and as its totally IPTV I need to ensure that the connection is as normal as can be.

Many thanks in a advance 🙏

Just in case the following data is also needed I have supplied the routers upstream and downstream stats.

Cant see images but does your inquiry involve what is discussed here?

https://community.virginmedia.com/t5/Speed/Packet-loss-and-upload-channel-32-qam/td-p/4983921

[Jsquires1990]

Thanks for the speedy reply, they seem to look similar to my BQM's - In the sense that between 4&10 the yellow is high! Thankfully not much red.

Hopefully the images will be approved ASAP

We are all facing the same thing my friend 😞

Hi @Jsquires1990 

As per the other posters, don't worry about the BQM just now as a large volume of customers are seeing teh same psikes at the same times. This is being looked into by the VM Network Teams.

Looking at your stats, they aappear to be good apart form the downstream Pre and Post RS errors

This may be an accumalation over time and not really affect performance. It would be better if yuo reboot the hub and then post those stats again in an hour or two. Resetting the hub will clear the currently showing errors and reset them to zero whhich will help determine if they are an issue.

I also suggest checking all your cabling, especially the white coaxial cable. Make sure it's snug and tight and free from any kinks.

[Jsquires1990]

Thanks Guys. 

I will reset and post the downstream stats again in a bit when not using the internet.

Here are the requested updated stats... I reset the connection about 1.5 hours ago.

Stats look good!

If your BQM is anything like mine then as of 6:00pm today its starting looking bad again.

Yesterday was bad from 3:00pm to 11:00pm.

Yes mine are bad between 4pm and 10pm, I am wandering why we are all seeing this issue. 

Are Virgin hiding a wider issue? - I am troubleshooting IPTV with Sky and they need to know its not a latency issue but sadly Virgin won't say yes or no. And the BQM could be incorrect!

Its a nightmare.
