Hi,

Are you still facing Belkin router blinking orange problem?
1. Take a pin or pen.
2. Press and hold the red reset button (it will be available in the back or bottom of the router) for 40 seconds.
3. Now Release the button and power off your Belkin WiFi router for 10 seconds and turn it back on.
