Appalling latency again, huge amount of uncorrectable errors - something is wrong!!!!

[RJMD]

Once again random ping spikes, stuttering, packet drops etc.  Extract from router:-

Note the huge amount of correcteds and uncorrectables on the 3.1 downstream channels - something is wrong, please sort it out otherwise I'm going to have to apply packet loss to the amount I am paying you...

[RJMD]

Here's the snapshot of the BQM that goes with that router extract:-

https://www.thinkbroadband.com/broadband/monitoring/quality/share/09ed315199112c5066481bccb9abfc6684...

As you can see, large amounts of packet loss towards the end. Please sort!!!

Is anyone going to pick this up?

Hi there RJMD,

Thanks for your post and welcome back to the community.

Apologies for the issues faced, from taking a look here I can see that there is another thread open regarding this issue, have you received a response on there?

Let us know,

[RJMD]

Hi Kain,

Nothing other than being asked to reset the router which achieved nothing.

Hey there @RJMD, thanks for the update.

The spikes and latency issues, is there any pattern to them or are they random?
The reason we ask is - there may possibly be an SNR fault that we don't know of.

Kind regards.

[RJMD]

Hi @Ilyas_Y

No pattern to them, although a couple of weeks ago they were happening regularly at 10 minutes past the hour, then it all started working fine again. At the moment I can see packet drops increasing again, probably because I'm downloading a large file at present. One point to mention, the 3.1 downstream is showing a huge amount of correcteds and quite a few uncorrectables, as below:-

Issue has to lie with networks, but it seems almost impossible to get it escalated to that team. Perhaps I should just end the contract on the basis I'm not getting what I'm contracted to, and go elsewhere?

Thank you for that information. When you aren't downloading anything, how is the service?
