Sometimes wifi module is unable to connect router

Question asked by Jackie Chau on Oct 20, 2015

My Android version is 4.4.3 and my custom target board uses IMX6. I have ported broadcom 43362 driver into, wifi can be ON and OFF. Then I conducted a test as below:

1. input correct password for the selected ssid

2. Wait for the wifi module to connect router

3. Reboot the Android system

Every times when I rebooted the Android, the Android should connect to router automatically. Then I rebooted the Android 30 times and observed the wifi signal shown in the Android system. In these 30 times reboot, there might be 2-3 times wifi module was unable to connect router. the logcat showed as below. In debug console, I could observe that if wifi module is unable to connect router, it will retry to connect again. However, Android didn't reply it. Does anyone face this problem and how to solve it? Thanks.
