when its on a llu dsl line that was syncing fine at 13mb for 12+ months that now can just sync at 4 mb ....

Damm ofcom/openreach smoke and mirrors definitions of what is a faulty line.ISP says nothing they can do as the line syncs at an average of >30% of the predicted maximum over a 24 hr period

get ISP to reset line profile? plug your router directly into the master socket, if its still causing problems, try the test socket.

If you are sure its a problem outside of your local house wiring then its going to be a hard battle with BT :S run some calculations online to see what speed you should be syncing at based on your routers line stats.

Can you post your line stats?
 
done all that tried a different router etc etc :( isp reset the profile will not sync above about 4.5mb target s/n ratio now at 12db instead of the previous 6 .

Line sync had been rock solid at 13.5 mb give or take a little for 12 + months till sunday evening when dsl disconnected and refused to resync on a 6db profile could not even hold a 7mb line sync. Phone ISP they reset profile to 15 db line syncs at about 4 mb , they then run 2 24 hr line tests during which the line averages a touch over 4 mb , to which they then say its unlikely they will be able to raise a fault to openreach due to the line being just under the magical 30% of max theroretical sync speed for the length .

Just stupidly annoying that they will not class a 60% drop in line performance on what was a rock solid line as a fault.

Is the decreased SNR the result in a loss of attenuation? If not, then it is a case of increased interference and there is probably not much Openreach can do.
 
Do the quiet line test on the phone, do it for a long time if you get any noise at all then you can raise it as a voice fault.

Be warned tho, the engineer will have to be able to hear the noise too, or you'll be charged.
 
just annoying as hell that they hide behind smoke and mirrors to say there isn't a fault when there was such a drastic drop off in performance , even going as far as re estimating my max line speed so it became lower so the current line speed was then above the magical 30% marker
 
Of course you could always find that the line to your house from the pole has an accident and gets damaged somehow, you know how these young thugs are thesedays... throwing trainers at lines and bringing them down and all that.

:p

There is a fault with the line, that much loss of framing over a 3 hour period is not right.
