the Telephone guy installed a couple of new sockets around the house

What type of sockets? Can you identify them from here http://www.kitz.co.uk/adsl/btsockets.htm ?

also took the stats from my computer which also are below.

What do you mean 'from my computer'? You always take the stats using a PC. It's the router stats you are reading from it. Do you just mean using the non-test socket on the front of faceplate?

If you hang fire a minute I've taken a couple of photos and I'll give you a link to view them in a minute.

I've uploaded 2 photos to the link below. These are the sockets he fitted today. Don't think there is anything wrong with them do you?

No. The faceplate was off. When I say computer I mean I opened the router admin page using the computer. The address for my router is 192.168.0.1 and took the stats from the router status page.

So what's the diff between the 2 sets of readings, Test Socket vs Main Computer? They are both taken from your PC using the test socket, you seem to be saying.

Sockets look good externally, but there could still be wiring faults within them. Worth checking and disconnecting ring wires as suggested.

The "Test Socket" readings were taken when the router was plugged into the "Test Socket" behind the face plate of the socket with the bar across it. The "Main Computer" readings were taken from the router admin page at 192.168.0.1.

Just texted the telephone guy to doubly check he disconnected the bell wire.

I know we are being a bit pernickety here, but please bear with us . The attenuation change is very odd, and you can see there is a significant connection speed difference.

The socket with the bar across it - is that the "1 of these" in your pictures, or a different one that looks the same, or something else? What socket was the "Main Computer" plugged into for the second set of stats?

Still very

There are a no. of factors for taking any stats reading, all of which are common to all readings:

1. The PC/device & browser on which the readings are displayed.
2. The IP addy used to access the router's GUI admin pages - always 192.168.0.1 in your case.
3. The socket the router is plugged into.

You have banged on about 1.) but it will be the same in both cases and it isn't at all important. However, you have never told us 3.) which socket was used for your 'Main Computer' readings. This is most important to know. Or perhaps you said they were also in the hidden test socket, but that can't be the case with such diff. readings.

There must be some difference between the circumstances of taking the 2 readings as the 2 sets of stats are significantly different, particularly the attenuations.

What am I missing?

This is becoming far too complicated.

The picture that says "1 of these" is where the test socket is and where the router was plugged into for the test.

The picture that says "3 of these" is where the computer was plugged into which enabled me to take the stats for the second test.
I do hope that is clear now.
