High latency & Packet Loss

[MauriceMoss]

Recently my connection has been experiencing high latency and dropouts this has gotten particularly bad tonight. Recently VM text saying on the 19th Aug 22 they had planned network work and it might affect my connection. I got the text on 22nd Aug 22 saying this work was now complete but since this time my network has been having random dropouts.
I setup a BQM on the 24th to monitor this and my latency has been higher with only a little bit of packet loss. But tonight it has been frequent packet loss.

I have a Gig1 package

BQM 24th Aug 22 (ignore the big block of packet loss at the start of this graph)
Ignore the packet loss at the start.

Adding BQM graph for 10/11/2022 as issue is still occurring.

[MauriceMoss]

 BQM for 11/11/22.

@Tom_W1 any chance of you looking in to this from your end?

[andrewmm]

Imho 

That's about as good as virgin get 

Great ping and latency, till you try to use it 

[Robert_P]

Hi MauriceMoss,

Thanks for providing us with the BQM's and additional information, when checking the connection for this end there does appear to be some SNR on your Upstream which will require a technician. I will send you a Private Message to get some more details from you in order to arrange this and look forward to hearing back from you.

Rob

[Robert_P]

Thanks for confirming those details MauriceMoss, I have booked a visit for the next available slot which you can view here via the MyVM app. If there are any issues with the date or time please let me know and we can look to alter this to something more suitable.

Please be aware that any changes would result in a delay to the visit as this was the earliest available, there also needs to be someone over the age of 18 in the property at the time of the visit. If there is a problem with this date or time please let me know via Private Message and we can look at alternate dates.

Rob

[andrewmm]

Or to put it another way. 

Take a day off work whilst I send some one who imho won't do much if anything, 

Roll on fibre to premis. No more docis. 

[Matthew_ML]

Hey andrewmm, I understand where you are coming from but we will get the issues resolved for you.

Please do keep me us updated on how the visit goes. Thanks 

[andrewmm]
