8.5 Meg, when it is running OK, seems exceptional for 52dB Attenuation.

It's not usually that high, usually between 35 and 45db.

I just looked at the graph again - this is EXACTLY the times my line used to drop connection and sync lower and lower and _{lower and :....}.

You are not in Pompey are you? I wondered that when BT fixed my line, they just swapped cabinet connections around so I got yours, and you ended up with mine!

Ah, that's more like it!

Perhaps that large jump in Attn. is a clue to the issue?

I'm not in Pompey no, I'm in Stoke Would have been funny to find out that did happen though.

I would do a voice only ticket, if there's a well defined voice fault independent of broadband.

Here's the graph from overnight:

There doesn't seem to be any consistency in when it happens and it didn't sync higher than 3000kbps yesterday, had to use my phone to tether most of the evening.

The SNR plot is awful - but what, I wonder, is causing the spikes?

Keep plotting until you have two full days of data

It's definitely external noise but I have no idea.

The plotting continues..

This is around 45 hours worth of plot data:
