I have my Master BT socket in a cupboard near the main door, with extensions in 3 different rooms. The junction box with cables feeding the rooms is next to my master socket.
Since the cabling in my house is Cat 5e, I am trying to convert extensions in 3 of the rooms to ethernet sockets, using a suitable faceplate. I successfully connected two of them and tested the connections using an ethernet cable tester. Speeds were also optimal, confirming that punchdowns were done correctly.
However, in the third room, when I wanted to repeat the procedure and removed the BT faceplate, I found an extra loose end of cable. At first I thought this was excess cable just stuffed in by the builders, but when I tested them, both appeared to be live... so one was originally connected to the BT socket and another was lying loose inside the faceplate! But my problem is that when I tried to repeat the ethernet connection in this room, my cable tester only lit lights 2 and 5, and skipped the rest. I tried different face plates and keystone jacks, but all to no avail. I am certain the punchdowns are perfect, and the cable tester works fine. Since all cables are behind walls, there is no way to test if there is a damage to this particular cable... although I cant think how this is possible since the other two are working fine despite being farther away from the cable box.
What could I be doing wrong?
And why are there two loose, live ends behind one single extension socket?
