WiFi Disconnect and Failed Reconnect

[lbussy]

On occasion, the WiFi connection will disconnect and fail to reconnect:

[WiFi-event] event: 5
2023-04-12T14:17:46Z W: WiFi lost connection, reconnecting ..
[WiFi-event] event: 5
[WiFi-event] event: 4
[WiFi-event] event: 7
[WiFi-event] event: 1
[WiFi-event] event: 5
[WiFi-event] event: 4
[WiFi-event] event: 7
[WiFi-event] event: 1
[WiFi-event] event: 5
[WiFi-event] event: 4
[WiFi-event] event: 7
2023-04-12T14:18:03Z N: Reboot request - rebooting system.
[WiFi-event] event: 5
[WiFi-event] event: 3

This seems to be the same as Wifi connection fails - only works after router reboot #8412 in the ESP8266 core for Arduino, and is explained REALLY well in ESP32 STA deauth frame causing reconnect issues (IDFGH-6544) #8192. The tracing tablatronix did here almost mirrors what I saw.

So now, I get to find a more graceful way (e.g. a hack) to recover from this because even if the newer core is better, it exhibits quite a bit more instability.

Thankfully, this results in a controlled restart (under Keg cop control) so it's not horrible. The worst part of it is that the compressor lockout may cause a kegerator to be off while that timeout runs out.

Did you actually fire up wireshark and see the same deauth frame coming through? I ask, as that's something I was experiencing personally earlier, but have not been experiencing since more recent versions of esp-idf (via more recent Arduino framework releases) have been available

I did, and of course I am using the older core.

"Good enough" for now. There is a compile-time define for TRY_WIFI_RECONNECT in wifihandler.cpp if I want to try again. Right now it reboots on WiFi failure.
