No exception, nothing. tried multiple configuration (1 or 2 core) different frequencies. I can't get this one to connect.
Any idea ?

"Fixed"

I erased my flash and now my wifi works.
I flashed it with my program for the first time yesterday. unused ESP32 chip. tested it. works ok, and today no luck.

We are using 2 different wifi access point that have the same ssid, password, but one is in wpa2 the other in wpa.
Could wifi messed up with the wifi nvs calibration thinking it was the same wifi AP using wrong setting ?

I remember that previously i tried to use WIFI without NVS and it crashed all the time. Can we now disable that ?
