Smart Modem Gateway VX420-G2H

Follow the instructions below to set up your Smart Modem Gateway (VX420-G2H) for NBN HFC.

First, ensure you have:

  • A message from us advising you to plug in your NBN modem.
  • 2x electrical outlets near your cable wall socket.
  • An Ethernet cable.
  • A coaxial cable.
  • An NBN Connection Box (NCB).
  • (Optional) Up to 4 additional Ethernet cables to connect devices via Ethernet.

An NCB should already be present if your premises has been previously been connected to the NBN HFC. If your NCB is missing, please call our Provisioning Team on 1300 300 509

  1. Connect the power cables from your NBN Connection Box and modem's Power Ports to electrical outlets.
  2. Connect the included Ethernet cable from the UNI-D1 port on your NBN Connection Box to your modem's blue WAN port.
  3. Make sure the electrical outlets for your NBN Connection Box and modem are both on, and press the modem's ON/OFF button.
  4. Allow 15 minutes for your modem to boot up and connect automatically.
  5. Check the lights on your modem. If the Internet light is green, you can start connecting your devices and getting online.

  1. To plug in additional devices via Ethernet cable, simply connect the Ethernet cables to any of the four yellow LAN ports on your modem.
  2. If you wish to use your Internode NBN Phone service, plug a compatible handset into the green PHONE port on your modem.

  1. If you wish to connect your devices via WiFi, you'll find the WiFi name and password on the modem's barcode sticker.

  1. Note: Whenever your modem’s 4G light is lit, that means your modem has automatically connected to the 4G Backup service because your NBN service is unavailable, such as during initial setup or network maintenance.

    Your NBN Phone will not work while 4G Backup is in use.

    Once you're connected to NBN, if you notice the 4G Backup service has turned back on for an extended period of time:
    • Restart your modem.
    • Make sure your modem is plugged in correctly for NBN.
    • Contact us if the issue persists as we may need to investigate a service issue.

Your modem will automatically connect your devices to the best WiFi network possible (i.e. 5GHz). Older devices may only be able to connect to the slower 2.4GHz WiFi. See WiFi Signal .
