My brother lives in Newbald, if you dont know where that is, it is here
http://maps.google.co.uk/maps?q=newbald&oe=&ie=UTF8&hl=en&hq=&hnear=Newbald,+United+Kingdom&ll=53.793756,-0.430527&spn=0.304602,0.617294&z=11KC vans had been seen working on the cabinet in Newbald for a while so when I visited my brother I logged in to his router to see what was happening......
upload was still slow at about 767 and only about 9000 downstream but a phone call to technical support ( Becky - very helpful) had this working after a few tweaks:
ADSL Link Downstream Upstream
Connection Speed 15999 kbps 1023 kbps
Line Attenuation 16.5 db 8.0 db
Noise Margin 9.45 db 10.0 db
I am sure that could be tweaked even more on a 6db profile, ( looks to be about 10db) but that is great !
