You are right about the wires. Pure blue and pure white.

Thanks again for taking the time to help

Looks ok to me. You can probably remove the orage (T3) wire. That's the ring wire and is probably not needed (see Kitz's page).

Yes that would seem to be the Master socket. According to an electrical catalogue the 422 is an MK Logic Plus Master Socket and contains the surge protector and capacitor.

Now that we have ascertained which is the Master socket I thought it may be useful to redo the stats as Roberto described above.

System Up Time 00:22:53

00:22:38

ADSL Link Downstream Upstream
Connection Speed 1287 kbps 524 kbps
Line Attenuation 39 db 11 db
Noise Margin 12 db 12 db

The increased speed used to be fairly normal for this time of day on a router reboot.

Here's hoping I can sort this out with your help.

Cheers

Carefully remove the connection on T3 at all sockets. See this page, even though your socket looks different.

Be careful not to disturb T2 and T5 as they do the work, and don't cut the T3 wires, just curl them up a bit so they can't touch anything that matters.

Do I need to do it on all sockets in the first instance or is it sufficient to do it on what we think is the master socket?

Normally sufficient on the master socket, but particularly where unsure of wiring layout, all sockets is worth doing

Right then. All the orange wires on all sockets have been disconnected (was a bit too eager on one extension socket and puled out another wire too but I can fix that when I get the little tool thing.

Line stats now as follows:

System Up Time 00:55:49

00:55:34

ADSL Link Downstream Upstream
Connection Speed 774 kbps 889 kbps
Line Attenuation 42 db 6.5 db
Noise Margin 12 db 12 db

Speed is now down as always haopens on a router reboot mid-afternoon. Not sure what to do next.

Your line attenuation has doubled, this usually indicates a move to ADSL2+

Not always and to explain to the layman, a 3dB change is equivalent to a halving or doubling of the actual signal level.

Line Attenuation 39 db 11 db
Noise Margin 12 db 12 db

To have downstream attenuation at over three times the upstream attenuation is unusual. Suggesting some odd fault somewhere.
