The arc display is a hardware abstraction that tells you almost nothing useful for diagnosing problems or evaluating placement. Underneath it is a real number, expressed in dBm, that tells you exactly where on the performance curve your device is operating. Reading that number directly converts WiFi troubleshooting from guesswork into measurement.
