Thanks for your replies.
Should add, Huawei AO1 infill and some earlier issues with the migration and left in links allegedly all fixed.
Alex,
That does look a bit much for me, but thanks.
Real,
Never seen comments before re a short line (167m) causing high noise margins.( interesting )
Should I see a 3dB on my short line ?
Is the ipprofile the same as BRAS profile ?
Current BRAS Profile (CVLAN Rate): 79672. Max attainable 89106.0, current noise margin 8db (and has been since the 8th of August)
Plusnet are very active in this fault and I do have a dedicated agent, have checked everything at their end, I do not have fixed IP ( first thing they did was switch to active )
PN have made several requests to OR the check wholesale profile etc but engineers on the ground have no access and getting it passed up the line has fallen on deaf ears.
I have had two lifts and shifts new NTE5 and several routers, PN have asked OR for a remake of the no more than 3/4 intermediate connections between house and cabinet, which they have refused to do, but have done the easy ones at both ends a few times.
Currently, as you say BT/OR are not dealing with speed faults.
Jelv,
Using several browsers, computers and a range of well known available test sites. ( I could list them if you wish ) and as in first post, taking the laptop to a friend on BT 80/20, HH6 and a 250m line it gets good downloads across the board around the 76mB mark, so it looks like the computer and browser are good.
My tests have been carried out with the router at the master socket and all internal wiring disconnected and always with a wired connection, no difference seen.
General...................
I find it very intriguing that speed tests report good download latency but sometimes poor upload with errors, but poor speeds down but very good up !, the lag at the desktop is very noticeable.
We have seen occasional RED line errors but these are not consistent and never there when OR arrive 2 days later.

PN agent previous comments...........
It's got to be a problem with the phone line, big enough to consistently restrict your throughput but small enough that it only very occasionally is evident on testing, as it was on Sunday with the significantly increased error rate. The window for getting an engineer out is too small.
