Q: Did the BT engineer fit a NTE5 split-faceplate master socket?
Answer: No, he fitted nothing new, all he did was disconnect my upstairs line - although he has left the upstairs socket in situ, and all the wiring, but he assured me it's all disconnected (which it is, as there's no dial tone). He probably knew it was all a complete waste of time, and that I'd soon be requesting it all to be put back how it was.
Q: If so, would you get your router stats by plugging into the hidden test socket behind the faceplate, with all phones and any Sky box type things completely disconnected?
Answer: Well, it's not a NTE5, and I thought I'd previously supplied all the router stats & line speeds, when I moved my computer & router immediately adjacent to my existing master socket/faceplate for the 2 day period (5th & 6th of March 2011). But heigh ho ............... here they are again :-

I will also move my router & computer back to the faceplate again sometime this weekend when convenient, and replicate the router stats process. I will have to choose a good time, as my wife has run out of patience with all this; she has no problem sending emails, so she does not understand what all the fuss is about

In summary, I was going to request a MAC number from Orange and switch to O2, however I read somewhere some bad reports about O2 as well. So my strategy is now to find out exactly when fibre optic comes on stream for my postcode, and if it's this year, I will sit tight and in the meantime squeeze as much as I can out of Orange

starting with an up to date router - as mine is 2 years old, as we are on a new contract with Orange (commenced last month), with a different family name on it.
Will be in touch over the weekend ......
