Just looked at my router...
ADSL Link Downstream Upstream
Connection Speed 6139 kbps 1021 kbps
Line Attenuation 44 db 13.5 db
Noise Margin 15 db 8 db
Hmm...
EDIT:
Now i don't want to pretend i know ANYTHING about connection speeds but in theory couldn't they up my line speed as my SNR is at 15 and can be stable at a bit lower than that?
EDIT2:
I rang them up and now i have,
ADSL Link Downstream Upstream
Connection Speed 8969 kbps 1021 kbps
He said that's most likely the max i will get. I'm happy as that's almost double my down and more than double my up

Anyone else near me got this? HU8 area.
