Bringing a modem from another internet provider

Most of the time, you'll be able to use the modem from your previous provider. Otherwise, we'd recommend checking with your previous provider if it is locked.

The modem port you'll need

Modems have 2 different types of ports which are used to connect to the NBN network. These are:

  • A 'DSL' port (uses an 'RJ11' cable) - this is the same as the old telephone cable you would use to plug your home phone into the wall socket.

  • A 'WAN' port (uses an ethernet cable) - this is the same as a cable you might use to plug your PC, PlayStation or other consoles into your modem.

Some modems have both of these ports, and some only have one. Check out the table below to see which port your modem will need to have to connect to your type of NBN technology.

NBN Technology

Port Required

Fibre to the Premise (FTTP)


Fibre to the Node (FTTN)


Fibre to the Building (FTTB)


Fixed Wireless (FW)


Fibre to the Curb (FTTC)


Hybrid Fibre Coaxial (HFC)


Note: If you are connecting via FTTN/FTTB, you will still need to check if your particular modem is ready to use on the NBN (even if it has a DSL port), it should be VDSL compatible. Some older modems (including those used for ADSL previously) may not be compatible with the NBN.

Access to the FTTN/FTTB Network relies on VDSL2 Equipment at the End User Premises. For the FTTB Network, the last segment of the distribution network uses in-building VDSL2 DSLAM infrastructure and copper twisted pair wiring. For the FTTN Network, VDSL2 is delivered to the premises via the local copper distribution network and a copper lead-in.
