Intermittent speed issues.
Again thanks for your help Kevin. 
Ok here we go.
Router is plugged in as follows
MASTER SOCKET - ADSL Filter - router supplied cable - router - LAN cable to PC.

Download speed achieved during the test was - 5.86 Mbps
For your connection, the acceptable range of speeds is 0.6 Mbps-7.15 Mbps.

IP Profile for your line is - 7 Mbps
I have my PN suppled firewall set to LOW
not much readings as of yet...

Chris,
This is really good in some ways, not that it resolves anything! Can you please clarify what kind of faceplate is on you master socket? See here - http://www.plus.net/support/broadband/master-socket-guide.shtml ; Does it just have a single 'hole' for an ordinary phone plug, into which you have plugged the filter?
Is the extension lead plugged into the 'phone side' of the filter or does that wire run off the back of the face plate?
Is any apparatus at the end of the extension wire fitted with a filter?
Are you able to leave the set up as is for the time being? It would be good to get router stats setup to monitor the SNRM and to keep an eye on the error counts.
The current line stats at the master socket are little different to those reported in responses #3 and #31, which to me suggests that there is (assuming nothing comes from the above questions) nothing being contributed by the internal wiring. The latency on the line (BQM graph) is diabolically bad - this could be exchange congestion or the consequence of a high level of retries on the line. I am hoping that the routerstats plotting might shine some light on this.
NTP / Firewall - you said that your PN firewall is set to low - is that "is now low" or "was already low"? Can you check the router logs and see if NTP is being successful? in a CMD (dos) prompt can you try to "ping ntp.plus.net" and confirm that you get a response. If you do not, please note the error and we can follow up on that.
@DCT,
Where next chaps? This link is synching below the maximum for ADSL(1) yet has plenty of SRNM headroom (10dB) and the line's attenuation (18dB) suggests it should go like a steam train if only ADSL2 (21CN) were available. So what's wrong?
Though I understand that "speed banding" is an ADSL2 (21CN?) concept, is this line somehow banded / capped / fixed to 8096kbps?
What are the likely causes of the poor latency? Exchange congestion? Remember this is a Scottish out of the way market 1 exchange with no 21CN serving around 670 residents - I bet it is a bit short on elastic bands!
Is this now a go direct to http://faults.plus.net or are there other things to be checked out first - full copper line test to check balance etc.?
Cheers,
Kevin
