How to properly modify sdkconfig ? Change some values, save it and that's it?

As far as why CONFIG_ESP32_WIFI_RX_BA_WIN was reverted back to 16, you’ll need to ask over on the arduino-esp32 github, as a subsequent commit made that change (go to the history view of the file to see the last two commits, or view the blame to see what commits were responsible for what changes).

The change to 16 was due to supporting PSRAM enabled boards. The PSRAM default is 16. I’ve been testing with a slightly adjusted values with near 100% success:
#define CONFIG_ESP32_WIFI_DYNAMIC_RX_BUFFER_NUM 32
#define CONFIG_ESP32_WIFI_SOFTAP_BEACON_MAX_LEN 752
#define CONFIG_ESP32_WIFI_DYNAMIC_TX_BUFFER 1
#define CONFIG_ESP32_WIFI_STATIC_RX_BUFFER_NUM 16
#define CONFIG_ESP32_WIFI_TASK_PINNED_TO_CORE_0 1
#define CONFIG_ESP32_WIFI_TX_BA_WIN 6
#define CONFIG_ESP32_WIFI_NVS_ENABLED 0
#define CONFIG_ESP32_WIFI_RX_BA_WIN 16
#define CONFIG_ESP32_WIFI_DYNAMIC_TX_BUFFER_NUM 32
#define CONFIG_ESP32_WIFI_AMPDU_TX_ENABLED 1
#define CONFIG_ESP32_WIFI_TX_BUFFER_TYPE 1
#define CONFIG_ESP32_WIFI_AMPDU_RX_ENABLED 1

I’ll be submitting a PR to bump to values which are compatible and stable for both WROOM-32 (no PSRAM) and WROVER (with PSRAM) boards.
