Hi can anyone advise please
Ive just changed from copper broadband to FTTC however with router plugged in to master socket via a ADSL filter ican get 22 mb with extension wiring connected it drops to 12
Ok so logic says extension cable is u/s but same happens with 52 ft of new cable laid across the floor and with only one of the 3 wires connected.
ie with any extension wiring connected be it 1-2 or 3 wires im at a loss to understand the problem.
Sounds like one of the wires is not connected correctly. Ensure terminal 2 and 5 are really securely in place and punched down really well. Do not connect bell wire, terminal 3.
Ideally just use the master socket, if you had an engineer install they would have made the master socket the fibre connection and installed a filtered faceplate, preventing you from using the extension.
