A persistent, flashing amber light indicates that any of the several potential conditions may require your attention: • The base station has not yet been configured because it is new, or the reset switch has been set. • You have selected a security configuration that is not recommended. • A new firmware update is available for the base station. • One of several other conditions, such as a disconnected Ethernet cable or invalid IP address has been detected. ref: [https://support.apple.com/en-us/HT202211|AirPort base stations: About AirPort base station status lights (LED)] To find out why your base station's status LED is flashing amber: • Open AirPort Utility • Click on the AirPort base station • Look for a Status setting in the small window that appears. Note: Status only appears if there is an issue or notification. Click on the small amber dot there and another window will open to explain what the "issue" might be.
