Due to where the master socket in our house is located, and the unwillingness of the owners of the house to request a BT engineer to upgrade the installation so the master socket is relocated, we use an extension cord for our telephone and ADSL modem.
The problem is finding shielded extension cable with the BT connector on it. I came across the solution that using network cable, because it's shielded, is an effective extension cable. The only issue is, I don't know what adapter is needed to convert a BT plug/socket to a network plug/socket. Any takers out there to help me in the right direction?
