This is the problem, from your previous post:
"Upstream 888 (Kbps.)
Downstream 8132 (Kbps.)
Operation Data Upstream Downstream
Noise Margin 16.1 dB 15.0 dB
Line Attenuation 17.3 dB 31.0 dB"
So yes, in a sense, EE fault management where correct when they said your line can only support 8.5Mbps but that is due, at least in part, to the downstream noise margin of 15dB.
