Which is around 2.75kms, which is pretty close to Andrew's estimate. You never know.

had open reach out with meaning fault sorted said itr was something to do with a "crimp", could some one please explain what that means ? now sync at 5728

A crimp joins two wires http://adeptnetworks.co.uk/index.php?route=product/p...

Result! .

herer are my line stats at the moment

ADSL Link Downstream Upstream
Connection Speed 5728 kbps 448 kbps
Line Attenuation 40.0 db 21.0 db
Noise Margin 6.5 db 21.0 db

i now only have a variation in noise margin of only 0.4db between day and night (moving between 6.5 to 6.1 ) before the fix my variation could be as high as 7db (moving between 9 to 2 )

i have now been connect at 5728 for 21 hours as yet my ip profile as not risen from 2.5mb,(ip profile before fix) should this happen in the next couple of days or could i have i stuck ip profile?

The maximum period for the IP Profile to rise is five days.

A huge jump can cause it to rise in less than 24 hours, but less than doubling of the connection speed doesn't seem to count as huge.

I think you are looking at 2-3 days in total, so another 1-2 days now. It's highly unlikely it is stuck, and there's certainly no point in contacting support until after 5 days.

It should rise to 5Mbps profile.

Crimp - the way that two bits of wire are joined together

many thanks once the ip has risen ,

is it worth hacking the snr to bring to down by 3db ( have netgear dg834g v4). Would that likely give me an increase of 0.5mb? manyt hanks

Tweaking the SNRM should be safe, but it would be very unlikely to cause the IP Profile to rise any quicker than now. I would leave it alone for now.

If you are confident about how much your noise margin varies 24/7 then maybe try it afterwards - bearing in mind that the next IP Profile step is at 6240kbps sync, so not easily reached, and any sync speed rise increases error rates. The small increase resulting would probably take at least 4 days to raise the profile to 5500kbps.

Unless 6240kbps is reachable and stable, your optimum sync is 5696kbps, as that is the lowest that gets 5Mbps IP Profile. As you are only 32Mbps above that there is no point in trying to drop to it. ADSL Max sync goes in 32kbps steps.
