With my home wifi or mobile AP (hosted from galaxy s8), esp32 always can connect correctly and get dhcp ip. However, here in my job (enterprise wifi), esp32 fail to connect OR fail to get DHCP or connect sucessfully. (random)
Please, help me to find WHY (or solution) to solve this problem. I have enabled all wifi log from menuconfig to help debug:
1. Here, ESP32 can connect to WiFi and receive DHCP sucessfully.
