*Note for nbn services with 4G Backup: 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.
