customer modified code(add print):

#ifdef MOXA_WLAN_LOG

{

           char buf[120];

           sprintf(buf, "MOXA_LOG=Disconnect from "FULL_MACSTR", reason=%d", FULL_MAC2STR(priv->cfg_bssid),reason_code);ç=我們只是把reason code印出來

           woal_broadcast_event(priv, buf, strlen(buf));

}

#endif

Hi, @yao_feng 

Thanks for creating case to us.

1. Customer is using too old driver and FW, it is recommended to use our latest driver and FW to have a try.

2. Whether this issue is only occurred in 2.4G? how about in 5G?

3.If possible, please request customer help to provide me Wi-Fi OTA sniffer logs to check what happened between STA and AP communication.

Best regards,

Christine.
