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

[RJMD]

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

Hi RJMD

Thanks for coming back to the thread. 

We've had a check today and cannot see any issues at all, no outages/issues, all levels in spec as well.

Have you gone round all the cabling to ensure it's all finger tight?

Best,

[RJMD]

Everything is tight, everything is configured as it should be. The huge number of corrected and uncorrectables on the 3.1 downstream, is that normal? So corrected showing at 2.8 billion, uncorrected at 194k - I'd say that figure is most definitely not normal, considering the router was only rebooted a few days ago. Can someone confirm?

It is normal for the corrected codewords to be very high. That is by design. The uncorrectables... At least one of the modulation profiles sees some noise. The log can tell us more.

[RJMD]

Do you need anything else from me?

JD

[Steven_L]

Thanks for coming back to us @RJMD, I have looked into this and cannot see any issues with your connection or in the local area.

Would you be able to provide a more recent BQM as the link previously shared is not working any longer?

Regards,

Steven_L

[RJMD]

Still the same issues, what do I have to do to get what I'm paying you handsomely for?

Roll on City Fibre finishing this street off, maybe with some competition Virgin might stop taking its customers for granted and giving them a second-rate service.

JD

[RJMD]

Usual issues, packet loss the minute I try to do anything with my gig connection...  Can this be escalated to networks, it has been ongoing for months and all I ever seem to get is "no problems seen this end", which is no use to me!  Latest BQM below,
