NBN CONNECTION BOX LIGHTS
If you’re like me, you’ve been seeing a lot of flashing and clicking from your NBN connection box lately. It’s been quite frustrating, as I’m sure it’s been for many others. Well, I did some digging and found out that there is actually a fix for this issue!
Has Your NBN Box Lights Started Flashing, Clicking or Changed Colour?
If your NBN connection box is flashing and clicking, the first thing you should do is unplug it from the wall. Leave it unplugged for about 10 seconds, then plug it back in. If the problem persists, you may have to call your internet service provider for help.

- ONLINE, DOWNSTREAM and UPSTREAM lights will all FLASH briefly when the Connection Box is powered on. This self-test is a way for you to know that everything’s working correctly without having too much output from your device or wasting energy in case there are issues with how it was set up before!
- If both UPSTREAM and DOWNSTREAM lights are FLASHING but the ONLINE light is OFF, there is no connection to the NBN network. Please call your ISP for assistance.
- If both UPSTREAM and DOWNSTREAM lights are FLASHING and the ONLINE light is ON, a firmware update is in progress. No action is needed – simply wait for the update to complete.
