ESP32 Forum

Hello Everyone, I have a custom hardware board that was using ESP32 WROOM 32d 16 MB. I was using this board in my home for last 1 year and had no problem with WiFi.
Now when many such boards are sent to customer, We find many complaints stating that WiFi keeps connecting disconnecting.
Is there any known WiFi connectivity problem with ESP32 with regards to type of WiFi router that people have. Because there are some people who do not have any problem.

I observe this problem as well. I have an old Apple Airport router and I have five ESP32 Pico kits (v4.1), all running the same software, connected to it.

The intervals are not regular, but roughly once per day or so all of them will simultaneously disconnect and then retry reconnection for about 40 seconds until connection is re-established. I have been researching the issue for quite some time now and have not determined yet why this occurs. Specifically, I've made a couple of different posts in this forum with log messages, but have not received any replies.

Please help to raise the issue on github with all relevant details.

Issue 7286 created.

I found that my connection/ disconnection problem was due a software bug caused by memory leak. So not really anything to do wih Espressif.
