Then,
This is my two files :

thanks I have one question
nano /etc/network/interfaces
===================================================
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*
this line is strange, this directory is empty in my case, I will comment out that line?

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# allow-hotplug eth0
# iface eth0 inet dhcp
===================================================

Comment all lines about all of your interfaces you will use with NM.

nano /etc/NetworkManager/NetworkManager.conf
===================================================
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true
===================================================

And set ifupdown to true to all NM to managed all interfaces.
Now your can create a new wired connection in NM with all the
parameters you want.

Bye.
