What do the LED lights on the front panel of the AC1600 indicate?

The front panel has five LED indicators: Power (solid green means normal operation, solid amber means booting), DSL (solid green means DSL connection active), Internet (solid green means connected to Internet, solid amber means connection failed), WiFi (solid blue means WiFi is enabled, blinking blue means WPS is active), and USB (solid blue means USB device is connected and ready). Each LED status provides specific information about the modem router's state.
