Check the nbn™ box (NTD) Fibre Lead Cable

If the Fibre Optical cable from the wall to the nbn™ box is damaged or not connected you will need further support, select the "NO" button below, otherwise continue troubleshooting.

Restart your nbn™ box (NTD)

First, let's restart your nbn™ box. This resolves any temporary device issue that may have impacted your speed.

  1. Turn off the power to the nbn™ box power supply at the wall outlet
  2. Disconnect the power cable from the NTD connection box for 2 minutes then reconnect the cable
  3. Turn the power back on to the NTD power supply at the wall outlet.

The nbn™ box will take 3 to 5 minutes to come online. Once back on, let's check if your connection has improved. If not, you may need to reset your modem.


Resetting your modem

If restarting your nbn™ box still doesn't fix the issue, we will now try to reset your modem. Sometimes, cache and temporary files can build up, slowing them down.

Remember, resetting your modem will remove any changes you have made to the settings on your modem, including Wi-Fi password changes - here's how to re-apply them

The modem can also take 3 to 5 minutes to come online. If you need help on how to reset the MyRepublic modem please click here.

As soon as your modem is back on, let's now run a speedtest to check if this fixed the issue.

To run a speed test, open  Make sure you choose the Sydney server before clicking GO. The test will only take about 3 seconds to complete. You will be provided with the download and upload results

If this hasn't fixed the issue, you will need some further help.
