Red or off lights on the NBN box usually mean a fault on the network outside your home. The tool below checks whether it's a known outage and tells you exactly what to do — including what to say to your ISP if you need to escalate.
A red light indicates a fault on the NBN network outside your home. Check the NBN outage map at nbnco.com.au/support/network-status first, then contact your ISP to lodge a fault if no outage is listed.
All lights off usually means a power problem. Check the power adapter is firmly plugged in at both ends and the wall switch is on. Try plugging directly into a wall socket instead of a power board. If lights are still off, contact your ISP — the box may need replacing.
Yes, try it first. Unplug the NBN box, wait 60 seconds, plug back in and wait 3–5 minutes. If the red light returns, the fault is on the NBN network and needs to be reported to your ISP.
Visit nbnco.com.au/support/network-status. Note this only shows outages affecting multiple premises — a single-property fault won't appear there.
