Can I connect my BT Hub using a telephone extension lead or socket doubler/splitter?

It's always best to connect your BT Hub to the master socket if you can. This is where the broadband signal is strongest, before it goes through any other home wiring which could cause interference. If this isn't possible, then use a new, high quality broadband ADSL extension lead.

It's always best to connect your BT Hub to the master socket if you can. This is where the broadband signal is strongest, before it goes through any other home wiring which could cause interference. If this isn't possible, then use a new, high quality broadband ADSL extension lead. Please note that this isn't possible for G.fast due to the socket type.

Follow this guidance if your master socket has one socket, like this:

Check your wiring and setup

  • The microfilter must be the first thing connected to the master socket, followed by any other equipment
  • To connect more than one device to your phone line, you'll need a splitter. The splitter must connect to the phone part of the microfilter
  • If you're trying to connect an EE TV box, this connects via Ethernet to your BT Hub. Find out more about setting up EE TV >
  • Some other TV services need a phone line, in which case the TV box must connect to the phone part of your microfilter. Please refer to your user guide or TV service provider for help

Scenario 2: Set-up where the phone is connected near the master socket and the Hub is located further away using an ADSL extension cable. Remember - using extension cables can affect your connection.
