Troubleshooting NBN HFC for No connection
- Check your address on NBN®'s Network status and outages page to see if an unforeseen incident or planned maintenance is affecting your connection.
- Locate your indoor NBN Network Connection Box and modem and ensure
that they are connected correctly,
with cables in good condition and plugged in securely.
Note: If you have an advanced setup using a network switch, this device should not be plugged directly into the UNI-D port on your NBN Connection Box as it will cause connection problems. You should have a router connected directly to the Connection Box, and then plug the switch into the router.
- Turn off the electrical outlets for both your NBN Connection Box and modem and leave them off for at least 10 seconds.
- Turn both outlets back on and wait for the box and modem lights to settle, then attempt to view a website.
- Stand next to your modem to rule out any WiFi signal issues. Move further away and monitor the WiFi signal strength.
- If you lose your WiFi connection in certain parts of your home, see our guide on improving WiFi signals.
- Attempt to view a website on a device connected to your modem via Ethernet cable, not WiFi. If Ethernet works but WiFi doesn't, see troubleshooting WiFi No Connection.
- If you can view websites on some devices but not others, see our guide on Browsing issues.
- To investigate your connection issue, we'll need your NBN Connection Box's Serial Number and CMAC Number. These details can be found on the unit's barcode sticker:
