So, is this about right or is there something I should be investigating?
Thanks in advance.

Noise Margin: 6.3 dB
Connection Rate: 4391 Kbps
Line Attenuation: 50.0 dB
A bit more information here http://community.plus.net/forum/index.php/topic,96155.0.html
However your speed in the BT test is a bit low - what does this give for Current Line Speed https://portal.plus.net/my.html?action=data_transfer_speed

Thanks for your time tonight.
I've made some small changes to your line which I hope should provide an increase in your downstream throughput speed. Test the line again tomorrow for us and I'm tipping things should have improved

Just run another test and things are a lot better.
@ oldjim, the current line speed via the link you gave is
Estimated line speed:
5Mb (This may vary between 4Mb and 6Mb) - Checked on 2012-05-22 16:50:21
Current line speed:
5.9 Mb
So I would appear to be above what can be expected at the moment.
For info the router status now is:
ADSL Link Downstream Upstream
Connection Speed 6784 kbps 445 kbps
Line Attenuation 43.5 db 25.9 db
Noise Margin 11.9 db 24.2 db

Are you aware of any bursts of disconnections
Perhaps a member of staff can look at the line history

The issue there is to do with the Attenuation - if that's over 30dB we'll usually set the downstream SNR to 9dB or even higher, rather than 6dB as it won't be stable otherwise. I suspect yours is set to 12dB because it's over 40dB, it may well not be stable if the SNR is lower than that.

Mike, can you post your current modem/router ADSL line stats and if there are any error figures CRC/HEC/ES/FEC/RScorrectable - that sort of thing, those as well.

@anotherone... I agree. My default margin is set to 3db, and currently is wonderfully stable. I am on 21CN ADSL2+
