The Orbi blue light issue can be resolved through a systematic troubleshooting process. Begin by ensuring the Orbi router is properly connected to the modem and powered on. Check for any loose cables or damaged connections. If the blue light persists, reset the Orbi system by pressing and holding the reset button for 10-15 seconds. Allow it to reboot and reconnect to the network. If the problem persists, try updating the firmware of the Orbi router through the admin interface. Lastly, if none of these steps work, contact Orbi customer support for further assistance in diagnosing and resolving the blue light problem.
