Over the past 10 days or so we have experienced a slow internet connection both downstream and upstream. Also there have been intermittent broadband service outages and an intermittently noisy line.
Here is a screenshot of the noise margin being achieved some minutes minutes ago. The first dip in the middle occurred after a 17070 test when I could hear noise. The outage on the RHS of the graph was spontaneous (as I was typing this) and a subsequent 17070 test revealed noise.
Does the level of Noise Margin variation seem normal ?
I have contacted the BT helpdesk who were helpful and have had two visits by an Openreach engineer. On each occasion the line has been tested and found OK, (although the guy said he was not a Broadband expert and did not comment on the Noise Margin variation) .
Help please !

Hi Many Thanks
The engineer fitted a new socket with a built-in filter.
We use a Billion router and I have tried to obtain the info mentioned - pse see below. Please also see the latest noise margin chart below which illustrates the multiple outages were ongoing up to 25 mins ago .
I have carried out many quiet line tests - some have noise, others are quiet ! The broadband has been working again since yesterday - hurrah. My belief is that there is intermittent noise on the line as can be seen in the Routerstats graphs - currently there are 2 dB variations in the Noise Margin for the downstream connection approx every 10 minutes - whereas the upstream is flat. (See below) My understanding is that on a quiet line the variations in noise margin should be very small ?
