Connecting your phone and internet to ADSL

These are the parts you need

Image of a list of parts you need.


Before you begin

Unplug old devices from your phone sockets. Unplug any existing modems, telephones and other devices that use the telephone wall sockets. If you want to use these sockets, make sure you have an ADSL filter installed between the socket and your device (purchase separately).

Set up steps

Plug the ADSL Filter into a phone socket.


  1. Plug the ADSL Filter into a phone socket

    First, you’ll need to find the right telephone socket in your house. If you have multiple telephone wall sockets, try the first socket closest to the front of your house.

    Plug the GREY cable with GREY ends into the back of the modem. Plug the WHITE cable on the other end into the telephone wall socket.

    If you have a telephone wall socket like the one pictured below, you’ll need to purchase an adaptor. These can be found at most hardware or electronics stores.

  2. Plug your Telstra Smart Modem™ into a power outlet

    Plug the GREY power adaptor into the back of the modem. Plug the other end into a nearby power outlet and switch it on. The Telstra Smart Modem will now turn on. When the front light indicator has turned green, you’re good to go. This may take a few minutes.

    Helpful tip! For the best coverage, place the modem in an open, elevated area, allowing for optimal signal and Wi-Fi strength.

  3. Connect your devices

    Via Ethernet cable

    Use the LAN cable with two YELLOW ends, inserting one end into any YELLOW port on the Telstra Smart Modem. Insert the other end into your device’s network port.

    Via Wi-Fi

    Search for the Wi-Fi name and enter the password show on fridge magnet provided with your Smart Modem.

    To update your Wi-Fi details, connect to you home network and open an internet browser window on your device. Type in http://mymodem or The username is admin and the password is Telstra. Once you are logged in, click on the tab marked Wi-Fi. Don’t forgot to click Save once you have made your changes.

  5. Connect your home phone

  6. Use your existing phone cable, inserting one end into your Smart Modem and the other end into your home phone. Check your Smart Modem, and when the PHONE light is on, you’ll be able to make and receive calls. Remember you must always have the modem switched on to make and receive calls.


Oh No! Something went wrong?

  1. Switch it off and back on and then wait a few minutes, you would be amazed how many times this can sort a problem out.

  2. Wi-Fi speed and other reception-related issues can be caused by the placement of your modem. Like your mobile phone, your Telstra Smart Modem needs good 4G reception to work in backup mode.

  3. Make sure your modem is elevated and not placed near items like fridges, fish tanks, microwaves, etc. that can interfere with your Wi-Fi.
