i have enclose a graph of my snr from router stats light showing noise on the line , i have been around the house and have had everything turned of and its still there , turned things on one at a time and it makes no difference
the wife has a vibro plate exercise machine that she has not used for a while and decided to have a go , my snr dropped from 9.4 to 7.8 while the machine was on with a decrease in noise on the line , i thought this was a drop in my snr at first but as soon as she turned the vibro plate of the snr jumped again , i got her to switch it on again and the same thing happened till turned of and un plugged from the electric , you will see the 2 times that the machine was on at the end of the graph
Any ideas or comments please

You're probably looking at one of two causes there.
The vibration machine may be causing a frequency that is conflicting with the high frequencies your router is using. Alternately it might be electrical interference.
Either way if possible I'd make sure the machine and the router are as far apart as possible. It may also be worth running power to the machine from an extension connected in another room just to see if it helps rule out electrical interference.

If the steps in the SNRM coincide directly with the switching on/off of the exercise machine then it's definitely chucking out some electrical interference that's affecting part (or all) of the ADSL spectrum. It's worth trying Adam's suggestion, even a different Ring main if you have one, but not only as far away as possible from the Router, but also the phone line.
TBH I'd be surprised if it makes that much difference but anything is worth a try in these situations. How much power does this machine use? It might be worth considering running it from an extension lead that has a Filtered socket on the end. Note Filtered, that's not the same as Surge Suppression.
As for your SNRM graph, it shows you still have some sort of problem with the line and the interference is masking some of the noise variations.

When it crops up bluntly report the noise on the line, and say you are sick and tired of Openreach doing nothing but test the line, say it's ok and not physically looking for the Intermittent break which certainly appears when it's windy. You have had dropped calls, as well as the noise disrupting calls and you expect something to be done.

Are the calls to/from the same phone (could the fault be at their end)
This says how to do it though you need a wired telephone
