Hi thanks for your response. It seems really informative, but I had a little trouble understanding a couple of your points.
Firstly, you say that BT have reverted to this cable style (i assume you mean the brown, orange, green, blue one that goes to my master socket) - but you say that it works for telephone but isn't great for ADSL. Why would BT revert to it then? Or do you mean the way in which the wires are connected is not effective for ADSL?
Thanks for your suggestion on how to rewire, although I had difficulty understanding point 4, since I don't have two screws available on the same side that aren't already being used by the solid blue/orange cables. The only screws that would be left would be on opposite sides of the junction box and hence joined together by the strip of metal - which would mean that those last four cables you mentioned would all be joined together?! I tried to draw another diagram of what you described to get a better understanding of it but it didn't clarify anything (no doubt my silly brain's fault!)
Also I'm not exactly sure how I would the attach an ADSL nation faceplate - presumably I would just attach the green and brown to pins 2 & 5 respectively (basically just duplicate what you are describing for the standard BT faceplate)
Although I would really like to better understand what you have just described (I much prefer fixing things myself - thus better understanding how they work) considering my (clearly mediocre) understanding of phone line wiring, proceedings may result in a long period of tinkering and possibly making the problem worse (at which point I wouldn't honestly be able to say to BT that I haven't changed any of their wiring/equipment)
I have a responsibility to my housemates/tenants to keep the internet/phone up and running as best I can within my power - so I think I am going to stick with calling out BT and getting them to rewire and fix the problem.
Since you obviously understand the BT engineering side - would it be sensible to encourage them to lay a nice shiny new wire from the junction box to the master socket? Is it likely to make any difference (bearing in mind all I really care about is broadband speeds rather than whether the extension works) Any tips to avoid them fobbing me off with a cheap fix (I've had that happen before with tradespeople who see a young female and think I won't know any better when it comes to the more technical side of things).
Also, since the wiring problem is before the master socket (hence their responsibility), presumably they shouldn't charge me for fixing it? I really hope they don't since am eating cold beans at the moment due to lack of funds (only reason I am bothering pursuing this is my tenants are bemoaning the speed problems - otherwise I would put up with it to save a potential outlay of money!)
