âś… Step 1: Restart your modem or router

Your modem or router is plugged into your nbn Connection Device (NCD).

  • Turn the power outlet off at the wall
  • Remove the power cable from the back of the modem or router
  • Wait at least 30 seconds
  • Plug the power cable back in
  • Turn the power outlet back on
  • Allow up to 3 minutes for the modem to reconnect
⚠️ Important: Do not press the reset button on your modem or router. This can erase your connection settings.

âś… Step 2: Restart your nbn connection device (NCD)

The nbn Connection Device (NCD) links your home to the nbn network at the curb.

  • Turn the power outlet off at the wall
  • Remove the power cable from the back of the NCD
  • Wait at least 30 seconds
  • Plug the power cable back in
  • Turn the power outlet back on
  • Allow up to 3 minutes for the device to reconnect

âś… Step 3: Check for outages

You can check for outages affecting your service using:

âś… Step 4: Check the lights on your NCD

The status lights on your nbn Connection Device (NCD) show whether it is connected to the network.

  • DSL light solid blue – the connection to the network is active
  • DSL light off or flashing – there may be a fault with the connection

If the DSL light is off or flashing, please contact our support team so we can investigate and log a fault if needed.

If both the DSL and Connection lights are solid, the connection to the nbn network is active.
