AZ-Delivery ESP32DevKitC Wifi reception heavily reduced after update

The problem

Hi there, since the 2024.6 update my sensor installed in my bathroom won't connect to my Wifi router next door anymore. If I bring it closer (within 4m range) everything works smoothly. Never had any issues bevore the update.

I tried two other identical boards to rule out any electrical malfunction: same result. I get a connection only if the sensor can "see" the access point.

I moved the sensor around in the house and tried next to other repeaters - always the same result. As long as I the sensor is very close (within 4m) to the access point, it works.

I also tried to provide the BSSID to the network configuration: no change in behaviour.
