NBN box or modem showing a red light — what it means.
The light on your NBN Connection Box (NTD/NCD) or your router is red or orange instead of the usual solid green or white.

- The NBN box has lost its upstream signal
- Power interruption has caused the device to restart in a fault state
- A cable between the NBN box and the street has been damaged
- Your service has been deactivated
How to fix it — step by step
-
1. Identify which device has the red light
The NBN box (mounted on your wall) and your router are separate devices. A red light on the NBN box means the problem is with the NBN line itself. A red light only on the router usually means it can't reach the NBN box or the internet.
-
2. Restart the NBN box
Unplug the power from the NBN box, wait 60 seconds, plug back in. Wait 5 minutes for it to fully reconnect before judging whether it helped.
-
3. Check cables
Make sure the ethernet cable between the NBN box and router is firmly plugged in at both ends.
-
4. Check for outages
Look at your ISP's outage page. A red light across a neighbourhood is usually a node or fibre cut.
-
5. Call your ISP
If the NBN box won't come good after a restart and there's no outage, your ISP needs to run a remote line test and potentially book a technician.
