I was in the need to move all my /etc/NetworkManager/system-connections (see here Move from one (broken) L5 to a new one step #6) to another L5 and all worked fine with one exceptionn: one connection to a Wifi AP where the owner months ago gave me the PSK of the connection. With the new L5 device it did not connect anymore. The small lock picture in the overview of all Wifi AP have had on click a small exclamation mark. I removed the file /etc/NetworkManager/system-connections/MagentaWLAN-TDUZ.nmconnection and restarted the NetworkManager with systemctl restart NetworkManager . It created the file again with a value key-mgmt=sae which I have never seen before. That’s why I changed it with an editor to key-mgmt=wpa-psk and with this at the end it connected. The diff of both versions of the file is
$ cat MagentaWLAN-TDUZ.nmconnection.diff

> key-mgmt=sae
I have here as well the /var/log/syslog of such failling try to connect. Any ideas what caused this and why it worked before with key-mgmt=sae? Did the Wifi router knew something about my L5 which was not there anymore due to the move to the new device?
