Billion 400G Router

[Mitt]

Hi
My router only shows the green power light, the rest only blink for a few seconds and be off when turned on. Any suggestions as to what could be the problem and how I can troubleshoot it?

What all is plugged in to the router?

I'd suggest reset it. there's a reset button on the back. Just press it with a pin while the router is on. Wait until all lights come on and it will start synchronizing again. If it doesn't work take it to a Telkom Store.
