Have you got any phone extensions? It has been a while since I had ADSL and mind is going fuzzy but the max attainable seems poor for that attenuation. Your noise margin is incredibly high which suggests there have been lots of disconnections bringing your speed down. If you have extensions then it could be an internal wiring issue. Do you have appropriate ADSL filters installed for all devices? It could be you have an electrical product that has a noisy transformer/PSU causing issues - some old Sky boxes were notorious for this.

We have had six years of misery, everything in building checked line replaced to pole , rain engineer checking interference , new filters router etc at the end of our tether one engineer that came out said the main cable from the box at the top of the road to our pole was defective but his manager would not allow him to pull a new cable through could this be the reason for these readings ? is there any independant way of checking we no longer trust BT they lie every other sentence

I take it plugging the router into the test socket makes no improvement?

Do you get any crackling on your telephone line when using a corded phone? If so, report a voice fault to BT (don't mention broadband at all).

What router is this? Your SNR margin is high and your sync speed is low. I suggest you try another router.

And given how BT Wholesale operator target noise margins high SNR figure does not suggest a failed router.

If after a reboot or modem/router the margin is still high, suggests high target margin as the result of noise as another poster suggested.

Does the maths for you and you are slow all around.

What is interesting is that the noise margin is a lot higher than the usual targets set, so a router reboot should reveal what that is set to.

Also the ADSL mode seems stuck on ADSL, when there are faster ADSL2 and ADSL2+ modes usually available (unless this is a rural connection with BT IPStream Max Premium service), so trying those modes might reveal some changes of note.

We are in Manchester, southerners may call that rural lol
to answer previous questions have a stack of routers - maybe enough to open a shop have seen so many so called bt engineers over the last six years several have given me different routers just in case
our internet is intentionally strangled by a senior BT tecky to try give us a stable line
are there any independent ways of getting BT's physical cables from box to pole checked in the uk ?

In reply to a post by JOHNRLBOWLING:

No, it's the most well-known city abroad outside London
to answer previous questions have a stack of routers - maybe enough to open a shop have seen so many so called bt engineers over the last six years several have given me different routers just in case
So what router were your stats taken from, a Voyager?
our internet is intentionally strangled by a senior BT tecky to try give us a stable line
Thanks for that rather important piece of information
are there any independent ways of getting BT's physical cables from box to pole checked in the uk ?
No, you will have to get Openreach to do it

It sounds like we aren't going to be able to help much as you are in the middle of a BT investigation and they have hamstrung your connection. That hamstringing in itself could impact on how the stats are displayed.

You haven't answered if you have extensions? Have BT/you tested from the test socket as another poster suggested?

And as has already been answered, only BT can work on the BT network.
