Connection speeds dropped and noisy line

Question

Hi there,
We will be calling BT tomorrow about this as we have had some crackling noise on our phone line over the past few days and the noise margin has shot up and the speed dropped, broadband connections keeps dropping randomly and sometimes the speed drops to 2mb instead of the usual 18-19mb I get.
When I plug the phone directly into the socket I hear no noise on the line at all, when I plug the phone into the ADSL adapter I still hear no noise, when I plug the router into the ADSL adapter I start to hear noise when the router starts to connect up.
Dont have a replacement adapter tonight to test this theory so thought I would throw it out there for experienced users to comment on.
Thoughts?
As I said before my noise margin has went up quite a bit since this issue.

The noise margin will normally fluctuate but only very small amounts. You should find that noise margin is higher about lunchtime and as it get dark and more use the phoenline then noise margin starts to reduce and get lowest about 11/12pm and then the cycle starts again
