This is all very odd.

I forgot we already had your stats. Are they all from the same socket? Attenuations:-

1) 43/13
2) 39/11
3) 42/6.5 (after the orange wire removal).

Are you using a plug-in phone extension cable in (1) and (3)?

Could this be aol traffic shaping? ie their way of trying to persuade me to switch to their platinum service?

No, traffic shaping doesn't affect attenuation.

It is odd I agree. #1 was in an extension socket. #2 & 3 were in what I think is the master socket. It is normal for me to sync at higher speeds on a weekday morning and for it to reduce in mid-afternoon. I can't say the attenuation rates are likewise because I have never really monitored them.

It is curious though...... I had always put it down to aol and users per modem.

No extension cables are being used.

Just a few thoughts.
1. Do any of your sockets have a pair of the usual BT colour coded wires, probably White with a Blue stripe, and Blue with a White stripe, or are solid colours used throughout?
2. Do you only have one Master, with all the rest being secondary sockets?
3. When you are measuring the router stats have you ensured that nothing else is plugged into any of the sockets?

1. I saw the striped wires in the other sockets. Cannot remember it if was all sockets but in all probability it was.
2. I think so. I remember seeing other codes on the other socket which were different from the code that was earlier identified as being a master socket.
3. Just the phone. But stats with phone unplugged and router rebooted are:

System Up Time 00:01:33

ADSL Link Downstream Upstream
Connection Speed 717 kbps 970 kbps
Line Attenuation 41 db 13 db
Noise Margin 12 db 12 db

The phone is filtered?

Yep, as is the router.

I don't think that is the master, or the wiring has been done wrong. The master should have a pair of incoming wires from BT and then extension wiring with probably 2 pairs.

That seems to show two cables with 3 wires, which isn't right if the incoming BT line is one of them.

Hopefully the BT or ex-BT engineers will agree that ideally two "striped" wires (the incoming BT pair) should directly connect to your Master socket, with the other cabling then feeding your extensions.
How about a photo of the sockets fed by striped wires plus their ident/catalogue numbers if possible? (If you have the MK Logic Plus Extension socket it's probably a K427).
