5 Wi-Fi LED State
After powerring up or resetting the device, the Wi-Fi LED will first blink once to indicate the
bootloader is in initialization process. Following the bootloader initialization, which takes about
4 seconds, the Linux kernel is loaded and starts the bootup process. When the Linux is booting up,
the Wi-Fi LED will light on steadily.It takes about 30 seconds for the Linux kernel to initialize
subsystems.
Once the Linux completes the boot-up process and the Wi-Fi subsystem is ready, the LED switches
off.The LED will have different behaviors according to different Wi-Fi configuration. AI7688H can
operate under 2 different modes, the AP (Access Point) mode and the Station mode. The AP
mode forms a Wi-Fi network that allows your computer to join, and the station mode allows
AI7688H to join other Wi-Fi network formed by other Wi-Fi access points.+
In AP mode
There are 2 Wi-Fi LED states in AP mode:
1. LED is off. It means no client device is connected to AI7688H.
2. LED blinks 3 times per second and pauses 0.5 seconds, and repeats the pattern. This indicates
there is at least 1 client device connected to AI7688H.
In Station mode
There are 3 Wi-Fi LED states in Station mode:
1. LED is off. AI7688H failed to connect to a wireless router and is timed-out.
2. LED blinks twice per second continuously. It indicates AI7688H is connecting to a wireless
router.
3. LED blinks according to data transmission. AI7688H has connected to a wireless router and
the Wi-Fi LED will blink as data is transmitting.
