SH.Hi, Just looking at my line stats and noticed this line –
InterleaveDelay : 0 800 (1/100 ms). It used to be 0 0
what does this mean ?

Is this with a DrayTeK, I forget, if so can you verify if your INP (far end) value has also increased, to say 15?

Yeah with the draytek 130

Looking at your stats and from my memory, looks like your ECI DSLAM still does not support G.inp, I had assumed BT would have sorted this out nationally by now ;-(
INP (Impulse Noise Protection) has been applied to your connection and hence the increase in InterleaveDelay – which means for whatever reason you connection maybe having short electrical impluses from external sources and so the connection has introduced INP to compensate for this interference and hence this has increased the InterleaveDelay which means (simplistically) a very slight delay in terms of time (milliseconds)
Does you connection drop at all ? or has line synch reduced ?

rare drop outs now, slower speed on down stream, increased ping.
What’s all you stats like, can you cut and paste them ?

Looks like you have lost 7Mb is speed and your DS Interleave Depth is 558
Was previously 1, so I assume either modem is being switched on an off regularly or you have an issue with noise on you line.
Is modem near microwave or on a shared power socket, if not you need to have a chat with BT ?
EDIT: has any DSL cables been replaced recently ?

It is not near a microwave, but it is in a shared socket with my Asus router.
EDIT – No

Is your BT cable underground or via Telegraph poles ?

Poles
Interesting, does the outside DSL BT line run via/near any street lights, tree branches or power cables (grid) etc?
Is so then you maybe having REIN / SHINE issues ?

nice video: https://support.zen.co.uk/kb/knowledgebase/broadband-understanding-rein-and-shine
maybe helpful to find REIN/SHINE with an AM radio receiver.

It is approx 2 yards from a street light pole, the street light pole is approx 5 ft lower than the BT pole where the wires connect to it and connect into a box on the pole.
