I'm not enough experienced to see that and deactivate it.

The two last blocks are for me useless because I am in IPv4.

# cat /etc/systemd/network/wlp36s0b1.network
[Match]
Name=wlp36s0b1

[Network]
Description=Configuration reseau de la carte Wi-Fi
DHCP=ipv4



Anybody can guide me ?

Thank you !
