A flashing white light on your Orbi device typically signifies it is in the process of booting up or resetting. During this phase, the device is initializing its system and establishing connections. If the flashing persists for an extended period, it may indicate an issue with the device's firmware or hardware. To address this, ensure the Orbi is plugged in securely, check for any loose connections, and if necessary, perform a reset or firmware update as recommended by Netgear support for seamless operation.
