Wi-Fi LED State
After powering 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 boot up 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
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.
