Hello,
I've upgraded firmware from 3.216 to latest 4.3.25 a few days ago. Since then, my IoT devices keep disconnecting from wifi (I have a bunch of ESP8266 and Wio Terminal arround).
Is there anything I can do to identify the problem and hopefully solve it? Worst case, I'll downgrade the firmware - but it would be a shame.
Thanks a lot for any hint,
Antonio
