Correct only 2 and 5 connected
Home hub connected to Bedroom 2 as explained in previous thread
Moved to hub to main socket (Lounge) and taken new ADSL Line Status
There is very little difference at that point.
There is nothing else you could do at this point without completely disconnecting the extension wiring from the master socket, and see if either the connection speed increases, or the noise margin increases.
I have no doubt that you have the skills to do that, but unless you have the correct IDC tool to reconnect the wires afterwards, there is nothing else you can do to prove that there is not an internal wiring issue.
Its quite possible of course, the general quality of the link may have deteriorated, perhaps due to pickup from an adjacent circuit on the MDF.
As more broadband, and especially Infinity connections are installed, the amout of crosstalk between adjacent pairs can increase. This can reduce the number of usable "tones", or reduce the bitloading on each tone, resulting in a decrease in connection speed.
Remember that the highest frequency used by ADSL max, is about 1.1MHz.
Even if you prove that the speed reduction is something external, its unlikely that even one of the "Broadband Boost" FTs would be able to improve on the connection speed.
The normal process is for them to change the master socket for a filtered one, but that would stop you using the extension socket to plug your home hub into. You would have to run a separate data extension cable.
If its not your wiring, then a filtered master socket would not help.
The purpose of this thread was to try and find the missing 2MB which was stable for 5 months which like BT india I have hit another brickwall, thanks for your help, but one last question.
Any idea who I can contact for further help or even arrange for an engineer to visit
Thanks for the information, yes you are correct I am a long way from fishermead but I am on the direct link from the exchange no cabinets we are the "E" side because when it was the Japanese school they paid to have a direct cable put in so I would have expected to have kept my 6Mb I was getting up till July this year.
BT still insist I pay £100 for a visit, even being a BT pensioner it had no impact on them, so hopefully FTTP may appear one day or even FTTC.
