Okay, I've just come off the phone with Eclipse Technical Support, which have stated they have no idea, WHY my speed of Downstream connection has changed, they've complete line tests, intrusive and non-intrusive, and have stated that I'm within th acceptable BT margin of 1.5 to 4 Meg.
They also stated that it's possible because BT have been adjusting the network, that may speed has been sacrificed for someone, that was not getting acceptable speed, and that's why my Downstream speed is halved, or they have put more houses on the network, and that is the reason by Downstream sync has changed. - This was what I was told, not sure if this is true!
They stated, my line is 4.5km, which last time I heard it was 3.7km.
Eclipse will now set my SNR to 3.0 as the target, rather than 6.0.
We will see if speed improves.
