ESP32-(S3) WIFI auth timeout

[clinnemann]

Hello everybody,

I am working on a project with the ESP32-S3 which relies on a fast wifi connection. Sometimes the wifi connection time is around 200ms which is very good but sometimes it is around 3,7 seconds.

When the wifi connection time is 3,7 seconds the order of events is always the same:
* Wifi station tries to authenticate towards the access point
* Wifi station does not receive the handshake from the access point within 1s
* Wifi station does a full network scan and searches the SSID
* Wifi station finds SSID (on the same channel as usual)
* Wifi does authentification and everything else without any problems

I have three questions:
* What is the best guess for the fact that the auth process does not go through correctly in the beginning? Why does it work out 1 second later? And this is consistently like it. First time problem. Second time no problem.
* Do you have any advice to get rid of this problem?

Best regards,
Christian
