MKR1000 AND MKR1010 code compatibility

Hardware MKR Family MKRWIFI1010
1

Hello everybody.

I have a proyect running in mkr1000 for a few year without issue .

Now I am migrating the code to a new device mkr1010, but I lost wifi connection easily.

It recovery but after 2 or 3 woork days lost ethernet connection definitely.

IO work when lost wifi connection with the exception of pin 13, which remains activated at high level, this is very strange for me
This always happens, when it loses connection, pin 13 is at a high level, although the code marks output at low level.

Mkr1010 have last firmware and i using last library...

Are there any important differences to take into account between the libraries or any incompatibility?

Thanks.

I have seen a somewhat similar report in the WiFiNINA library's issue tracker:

and the associated forum thread (which contains some advice for how you can write your sketch to be resilient to occasional connection loss):
https://forum.arduino.cc/index.php?topic=664834.0

From reading that, there seems to be a correlation with the use of the "Fritz Box" network hardware. Are you using this also?
