What results do you get from this BT tester?

Download speedachieved during the test was - 1077 Kbps
For your connection, the acceptable range of speeds is 400-2000 Kbps.
Additional Information:
Your DSL Connection Rate :1440 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 1250 Kbps
Thanks for interest
Mike

Your previous BT profile was 750, and has now increased to 1250. This is probably because your connection has settled after a period of instability and as such the DLM (BT's system that monitors the line's stability) has increased to show this.

Quote from: mikesin "why do I have to do all of the analysis on what is going on " was my attitude....
Because, your own internal wiring and equipment (which is a very significant cause of connection and speed problems) is your own responsibility. If you can't be bothered to check a few basic steps, then the problem can reoccur.
Of course, if you could post a few more stats on your line, then it may be possible to increase your speed further, stabilise the line, or find a fault. That's if we can be bothered.

The wiring in my house has been checked on a number of occasions. I havetried relocating the router to the entry point of the BT circuit . I have hacked into my old BT router and run speed tests with that and this has given me BER which shows clean BT line and internal wiring.
So I have been bothered in the past to do all of the things I could - even removing the third wire from the BT circuits but these reconfiguration events get very tedious when it is shown to have no bearing on the erratic speed I am achieving.
So why do i get instability that causes the line speed to fall away and what can I do about this ?
Thanks to Apprentice and Jojo

With the amount of information you have provided so far, nobody can say. Plusnet may be able to infer something from their records but we need to know what your router is up to, as Barry wrote earlier.

Your line is doing the best it can given the noise margin of 7dB
The only possibility of improving it is to try the test socket but it may not make much difference.
You need to be aware that if your router resyncs over night or indeed in the evening the speed will be significantly lower and will drop the IP profile down to 1000 or even 750
You can see the numbers here http://www.kitz.co.uk/adsl/IPprofile.htm#IP_profile_calculated (near the bottom of the page)
At present you have just crept into the 1250 band

"Aug 25 08:21:20 SNTP Synchronised to server: 212.159.13.50 "
" Aug 25 07:21:20 SNTP Synchronised to server: 212.159.6.9 "
my speedtouch does it on an hourly basis.
Is this normal? and can I stop it?
thanks

That is your router checking the time.
A resync is where the router disconnects and reconnects to the internet connection.
When it does that it negotiates the connection speed with the exchange based upon the default noise margin set by the exchange. I assume that yours is 6dB which is the lowest (i.e. best) value so you get the highest speed.
However the noise margin is the margin over the noise on the line (electrical noise not audible noise) and in the evening this background noise increases and reduces the speed it will connect at.
To use an analogy
If you were listening to your radio across a quite room you could hear it easily and understand the words. If the room is full of people chattering then to hear the radio properly you would need to move closer to it.
To explain further - To hear the radio and understand the words the sound from the radio must be higher than the surrounding noise (this is the noise margin) and in the case of the broadband signal the way it overcomes this is to reduce the speed of connection.
