yes i have
yes managed to see stats and obviously connection time very low and the constant restarts have caused the DLM to take action and reduce your connection speed and increase your noise margin in an attempt to stabilise your connection
was quiet line test totally silent?
have you managed to try using test socket with a filter?
I think the quiet line test is ok. I am not using a filter as BT say a filter is not necessary with a smart hub 2. Any ideas?
the quiet line test should be absolutely silent when using a corded phone any noise on line is a problem
you need to use a filter if you connect your hub to the test socket to see if that stabilises your line
which master socket do you have
BT are talking nonsense, a filter, either incorporated into the master socket or external, is required with all hubs.
You need to use a filter if connecting to the test socket in order to provide a conversion from the rj11 plug that doesn't fit the test socket to a phone plug that does.
if you have master 7 then that is newest master and the faceplate just unclips - no screws. if you take off master then you can see the test socket and you need to use a filter as described by @licquorice to enable you to connect the cable from the hub
once connected then repost hub stats and leave hub connected if possible for couple of days and see if now more stable
