Return of Upstream Issues

[gary_dexter]

Hello,

Around 6 months ago there was an area issue with capacity/congestion that was resolved under fault reference F008718191 - the thread for this is below:

Update on fault reference F008718191 - Virgin Media Community - 4651268

It seems that there is an issue again as I am regularly seeing packet loss on my connection and BQM, and my upstream channels keep dropping to 16 or 32 QAM - I also had a total loss of service on Friday night for around 15 minutes or so - and when the connectivity was restored the Upstream levels stayed on 16/32 QAM until I got bored checking them and went to bed.

Please can someone investigate why this is happening - another forum member, @Tazz also lives a street away from me is connected to the same Cabinet and is also experiencing the exact same issue - so this is not just localised to my home connection.

His thread on the previous matter is located here: Re: Gig1 Latency issues Bracknell in the evenings - Page 9 - Virgin Media Community - 4476643

Thanks,
Gary

Hello

Just to add to the excellent post by Gary I can confirm we both are seeing the exact same issue as last time found to be a network and not a local issue. Please can we raise this with Networks again?

Gary.... I hesitate to say.... but you have checked for known faults on 0800 561 0061 - havent you 🙂

You know the ropes - but did you try calling it in to see what they say about the connection - if not post up your stats and the BQM link - and I will flag for VM to come and take a look.

[Tazz]

I checked and it says nothing. Connection dropped twice in last hr and all channels were lost and found again. Maybe they are doing works?

From my experience works are you on the local telephone enquiry line.

It seems Gary did not get the drops too:

Back to 32QAM on 2 channels now:

This is still happening.

BQM shows packet loss (almost constantly) and T3 timeouts keep rising.

Hi there @gary_dexter and @Tazz

Thanks so much for your posts and so sorry to hear you are both experiencing these drops. 

Please can you provide a link to an active BQM and the dates and times of the drops? We will look into this and see if networks can provide an further information on what might be causing this. 

Thank you.

Here are some recent BQM snapshots - as you can see it's pretty consistent and the Upstream QAM keeps dropping to 32QAM..

And here are mine. Also seeing drops down to 32 QAM as shown above. Lots of packet loss while gaming too... Cant wait for City Fibre I am outta here as soon as they finish the install in my street.
