i was receiving 12000 downstream on O2 and have been unsuccessful so far in achieving the same on Sky. Apparently, i'm on the gaming configuration and everything possible has been done to speed up my line.

My stats as of now:

Connection Speed 8449 kbps 1105 kbps
Line Attenuation 38.5 dB 23.6 dB
Noise Margin 6.0 dB 8.6 dB

i am off 3500 which is a lot. I don't have a test socket and no extensions.
Any ideas?
