We have around 80 ESP32 based wireless devices in a center. These devices communicate with our local server which is assigned a static IP. We have a live TCP socket from each of the device to local server. This socket reattempts connection if device doesnt hear from server for 20sec.

This goes on for around 1hr or so and then most of the time situation self resolves. If we restart the access point/router we see improvement in the situation but it does recur. During the period of 'reconnections' even HTTP requests from devices to server start to fail. Pings from server to device IP times out too. We can see in access point that the device ...
