That carrier load table shows the tones/frequencies that are being used
by your router. The more frequencies used, the greater the bandwidth.
You are currently only using a little over half the available frequencies for
an ordinary ADSL line or about a third of those available if your exchange
is enabled for ADSL2+. I reckon that, if the noise/interference on your
line is sorted out, you ought to get easily more than 3Mbps.

Also, the attenuation for your line is not ridiculously high. The Max speed
calculator on the Kitz site (Linkie) even suggests that you might get as high
as 5 or 6 Mbps.

Have you ruled out the possibility that the noise might be coming from your
internal extensions. Did you test in a master socket where you can isolate
the house extensions from the incoming line completely (NTE5) ?

Both Talk Talk and BT suggest that my phone number should have a max speed of about 3Mbps, which I used to be able to achieve.

Yes, I have tried plugging the router into the BT master socket with no phones, or anything else, connected and using a long Ethernet cable to connect to my computer.

There seems to be almost no difference in the router stats whether it is plugged into the master socket with nothing else connected and my normal setup with the router plugged into an extension socket which is about 1 metre from the master socket and two phones connected.
