I tried the link and its estimated 33-47 mbps but on my router statisics tested at:-
Broadband Link Downstream Upstream
Connection Speed 27817 kbps 7235 kbps
Line Attenuation 22.6 dB 0.0 dB
Noise Margin 6.1 dB 5.5 dB
PS........I think I will call them tomorrow.
If your Estimated Access Line Speed (EALS) is 33-47 you really should have been talked OUT of taking Fibre max. It's clearly not a suitable product for you.
Max will be available to buy on sky.com on Tuesday, not Monday.
