As per the title , what is an acceptable noise margin in HH5 stats ?
Mine was always running at around 6.3/6.0 but now suddenly it has gone to 6.3/9.8 😞
Accordingly my connection speed has dropped too.
normal is about 6db so if you have now jumped to 9.8db and dropping connection it appears there is a line noise problem and errors which have resulted in DLM increasing noise margin. the result of higher noise margin is as you say reduced conenction speed
try quiet line test
Quiet line test seems normally quiet tbh.
Connection had been very stable since last Openreach visit. The increase in noise margin has dropped my connection speed from 32 to 24.
Looks like this may have been a temporary glitch.
Things seem to be returning to normal. Noise margin 6.0/6.7
Obviously I'll monitor this and see if things stabilise back to where they were.
Oops , spoke too soon. Noise margin back to 8.4 and connection speed dropped again 😞
Can anything be done about this ?
Why would the noise margin begin fluctuating instead of staying around 6 ?

Your connection has reset hence the noise margin increase. Is there any noise on quiet line test as there is an underlying problem causing the resets
