    Setting it up

    The 5G modem connects wirelessly to our 5G network and to your devices, so there are no ethernet cables or extra boxes. Just plug it in where you get the strongest 5G signal at your property, as shown on the modem placement guide in the My Telstra app.

    A strong signal is indicated by the green light on your modem.

    Follow the simple steps in our user guide for a Gen 1 or Gen 2 modem:

    Which version of 5G modem do I have?

    There are currently two different generations of 5G Home and Business modem. Look on the back or base of your modem to find the model number.

    Where should I put my 5G modem?

    The placement of your modem is important to get the best speed and performance.

    Optimal position
    Optimal position

    You should try to set up your Telstra 5G modem: 

    • In the optimal location shown on the modem placement guide in the My Telstra app. The guide includes a map and satellite view to help. 
    • With a view out a window. 
    • On a higher level if you’re in a multi-storey building.
    • In the open, not behind closed doors or in a cupboard.

    A strong signal is indicated by the green light on your modem.

    Don’t place your modem near large metal objects that may block or interfere with its signal, such as refrigerators, microwaves, TVs, or steel-mesh window security screens.

    About your modem

    The lights on the front of your modem are used to indicate connectivity, and each light indicates something different.

    Usually, your Status, Signal, Internet and Wi-Fi lights will be solid green, meaning you have a strong connection to the internet on either a 4G or 5G network. However, sometimes they might be flashing, showing a different colour, or off entirely.

    Check the set up guide for 'What do the LED lights mean?'

    No. Your 5G modem is locked to your location, which means you can only use it to access our 5G network while it’s at that address.

    When moving, you must cancel your 5G Home or Business Internet plan and return your 5G modem to us in good working order.

    Eligibility checks will apply to determine if you qualify for 5G Home or Business Internet at your new premise.  

    Whilst there is some impact to signal strength caused by extreme weather conditions, this is minor and no different to the impact on 4G signal strength.

    Simply unplug it, move it and plug it back in. There’s no need to reset the device. When you plug it back in, your service should come online and your devices will reconnect.

    The antenna inside your device is equipped with a range of smart features that allows it to out-perform most external antenna systems. For that reason, we don’t recommend using an external antenna.

    If you can’t receive adequate signal strength in your location, a professionally installed rooftop antenna may address the problem. Please seek professional advice if you’re considering that option.

    If you need a longer power cord to reach the best position for your device, we recommend using a general-purpose extension cable of an appropriate length.

    We don’t recommend using a low-voltage Male to Female DC Jack extension cable or third-party power supplies, as they may not supply adequate power.

    Most customers connect their devices over Wi-Fi, but if you do need to connect with an ethernet cable, CAT-5e or CAT-6 cables up to 10m long are typically available from IT shops and electrical appliance retailers.

    Using 5G internet

    Sign in to My Telstra and go to Services. Select your 5G Home or Business Internet service to manage it and check data usage.

    To update your 5G modem’s Wi-Fi settings:

    1. Go to in your browser and sign in with your username and password
    2. Select Wi-Fi settings 

    From this interface, you’ll be able to change the Wi-Fi Name (SSID) and Wi-Fi Security Key.

    Keep the new Wi-Fi name and password somewhere secure and private. When you update them, you may be logged out of the network and need to re-enter the new details. If you forget them, you can factory reset the modem to go back to the default settings.

    The default username for your modem is admin. The default password for a Gen 1 modem is Telstra and for a Gen 2 modem it’s your Wi-Fi password.

    We recommend not cancelling your existing internet service while you try 5G Internet to make sure it’s right for you.

    If you haven’t cancelled your existing internet service, you can simply cancel your 5G internet service and return your 5G modem to us in good working order.

    If you already cancelled your previous internet service, you’ll need to order a new one.

    If you cancel your 5G internet service, we’ll ask that you return your 5G modem to us.

    To cancel your service, contact us.

    Once your service is cancelled, we’ll provide you with an eParcel consignment ID. Take that with your modem to an Australia Post store and they’ll take care of it from there.

    We’ll cover the postage, so there’s no cost to you. This is the simplest way to return the modem and allows you to track the return. Telstra stores can’t take returned modems.


    You can run automated tests on your service to diagnose and resolve your query.

    Troubleshoot a problem

    Message us if you’re still having trouble:

    5G Internet can be affected by the location of your modem. The 5G modem placement guide in the My Telstra app predicts the indoor coverage for your modem at the address displayed. It’s as accurate as we can make it, based on what we know.

    Indoor coverage is highly variable and there may be locations where indoor coverage is indicated, but your device may not perform as expected due to local building density, physical structures and building materials.

    For example, the following things may reduce or block indoor coverage: basements, lifts, underground carparks, concrete buildings, tunnels and road cuttings, steel framing and metallic window film.

    It's recommended to place your modem within the optimal location at your address, as high as possible and close to a window.

    If you’re still not happy with your service after placing the modem in the optimal location, message us for support:

    Some older devices are unable to use the latest security features in our modems. If so, you may need to change the Wi-Fi network security mode to WPA2:

    1. Go to in your browser and sign in with your username and password
    2. Select Wi-Fi settings
    3. Change your Wi-Fi network security mode to ‘WPA2’ and Save.

    The default username for your modem is admin. The default password for a Gen 1 modem is Telstra and for a Gen 2 modem it’s your Wi-Fi password.

    Our 5G modems rely on passive cooling and are designed to operate under Australian conditions, so may become warm to the touch under normal operation.

    For passive cooling to work, your modem must be installed upright on a flat surface. If it’s installed upside down or on its side, or airflow to the base is blocked, it may overheat and shut down.

    To avoid excessive heating, the modem will shut down if the internal temperature exceeds 85 °C. This won’t damage the device, but it’s less likely to happen if the device is installed appropriately.
