If you want to use esp_wifi_internal_set_fix_rate, please disable WiFi AMPDU TX by:

Re: wifi/event broken in latest 4.0

HI Danny, the example code in IDF v4.0 works well on my side, could you let me know the type of router to which the ESP32 station is connected? Did you correctly configure the password and SSID of your station?
