I'd like to install another socket in another room while leaving master where it is.
I understand I can remove the face-plate and cable the A and B broadband extension to another socket..but could someone advise which extension socket/wiring details?
If I can only extend the Broadband that's fine. I just don't know which socket to use on the slave/extension.
Are you using a BT Home hub?
Why not just use an RJ11 extension lead plugged into the broadband socket on the front?
Because I want to run the cable externally and into another wall socket
Then you would need to connect to the data extension terminals, shown in blue on this picture. Only two wires are used.
The socket on the right is what I have (mk3) and the one on the left I have one of those too as it happens (spare room)
Can I use another MK3 (data extension <> data extension) so I can use rj11 case or do I require a different type box?
