Cannot disconnect Ethernet
I have been using NetworkManager for long time in Opensuse and disconnecting Ethernet from the applet or with nmcli always worked fine.
But recently I installed arch linux on my notebook with NetworkManager Version 1.24.2-1.
If I now press the disconnect button under the Ethernet-connection (which I called wired_1) in the applet the connection disconnects but after a short time is reconnecting under a new temporal name (enp3s0).
The same happens if I type
nmcli connection down wired_1
in the terminal-emulator.
Is this behavior a regression of NetworkManager or is arch linux the culprit?
