Yeah will do, thanks
A straw poll of my estate has demonstrated that those who ordered online got offered 2 and those who ordered by phone were told that only 1 was available as we would not be able to achieve the speeds of 2, so, as Saffy said, being a new estate, I suspect there are issues with the online system, possibly making assumptions.
Out of interest, would changing the flimsy RJ11 cable that came with the HH5 for a nice beefy (what looks like cat 5) RJ 11 cable I bought a while back make any difference?
The chappy who came said no, and he also said no point putting cat 5 between the open reach box and the master.
Though, I am more inclined to go with the advice here.
