I'll put up some more photos in the morning. I know I have seen some striped wires but need ot check where. From memory I think it could be the master bedroom.
Could the buildeers really have been clever enough to think of putting the master socket in the master bedroom?
If it is that socket then that is the one I messed up on with the orange wire and pulled a (I think) blue/white striped wire out too. The socket no longer works but the other sockets work. I wonder if this could have caused the db change.
I won't hazard a guess until we see your photos.
In my own BT installation a blue/white and white/blue pair run from the external junction box to the first socket, a master, which is an NTE5.
Hopefully the photos will enlighten those of us trying to help you with the wiring.
As Roberto says, the change in attenuation in your case may well be a symptom of faulty/mis wiring.
My plan would be to establish without doubt which is the first socket fed by the external junction box> Ensure that it is a Master "type" socket> Disconnect ALL cabling from it other than the incoming pair > Ensure you still have dial tone! > Connect router and check stats. Once broadband is sorted restore extensions one by one, keeping an eye on router stats
