On http://www.dslchecker.bt.com/ it gives two sets of figures for Downstream, e.g. for me:
Downstream Line Rate(Mbps): Up to 1.5
Downstream Range(Mbps): 0.5 to 2.5
Why the two figures / what's the difference between them?
My actual Downstream (from the homehub stats) is 1.688 Mbps, it used to be 1.8 something a while back though.
