This seems to finally fix/workaround the bug that has been plaguing WPA2 connections.
In my testing (home network, WPA2 Personal), connection time has improved from ~1200ms to ~300-350ms.
The issue seems to be that the underlying WiFi API needs esp_wifi_set_config() to be explicitly called. Perhaps some lwIP settings aren't applied. It might even be a clash with the ARP check config specifically.
This is not specific to Arduino, but it is a band-aid for now. Also tested with esp-idf (PlatformIO) , esp-idf + Arduino component (PlatformIO), Arduino (IDE and PlatformIO).
I'll create an issue on the esp-idf repo soon.
Hopefully helps with #1675, #2798, etc
