ESP32 randomly disconnecting from WiFi after a few hours – anyone found a stable fix?

Hi everyone,
I’m working on a small IoT project using an ESP32 board, and I’ve noticed that the WiFi connection randomly drops after running for a few hours. The board reconnects sometimes, but other times I need to restart it manually.

I already tried using a stronger power supply and updating the board package in Arduino IDE, but the issue still happens occasionally. Has anyone dealt with something similar? I’m curious if this is more likely a code issue, power stability problem, or maybe a WiFi sleep setting I missed.

Would really appreciate any advice or examples that helped in your projects. dordle
