I've recently had broadband installed (with fibre to the cabinet). The download speed is only 2 meg as opposed to the predicted 9 meg. The previous owner of the house had several phone sockets installed (on the same phone number). I haven't ever used these phone sockets before but tonight I plugged a phone into 2 of the bedroom sockets and the line sounded extremely crackly in both rooms. I then plugged the phone into the main socket in the lounge and although this line wasnít crackly if I made or received a call, the broadband disconnected when I used the phone. The modem and hub are connected to the socket in my office which is only just across the hall from the main socket. I can make and receive calls fine as long as the phone is connected to the same socket as the broadband.
I tried to test the sockets both with and without filters and the filters made no difference (the broadband disconnected whether a filter was attached or not to the lounge phone).
My question is: are these crackly phone sockets in other rooms slowing down my fibre to the cabinet broadband and if so, is it an easy job for BT to disconnect these sockets? I donít need the use of the bedroom sockets, evidently these sockets must have been fitted before the advent of mobile phones.
It is a bit of a mystery why there is so much interference on my line that is slowing down the broadband Ė is it likely that these other sockets are effectively diluting the quality of the line?
