"Cable unplugged" is gray.

inxi -Fx shows network driver:

Network:   Device-1: Intel Ethernet I219-V vendor: Lenovo driver: e1000e v: 3.2.6-k port: efa0 bus ID: 00:1f.6

It looks like disabled by default.

Can anyone help me to enable this device Ethernet ?

Your last picture is for a USB to Ethernet Device. But your inxi output shows a internal Ethernet Adapter.

Which one is it? Also if you are sure you plugged a Ethernet cable in, try a different one.

I use the docking station for thinkpad.
Ethernet connects with the docking station.

Three weeks ago it worked fine with Manjaro KDE.
Then today it doesn't work

So what happens if you plug it in your ThinkPad directly?

If I plug it in my Thinkpad, then network symbol reacts on the top panel and network manager refrehs the connection automatically, then Ethernet stays off

In this case you need to check the journal. Gnome uses by default the Networkmanager.

journalctl -b -u NetworkManager.service 

I found out that LAN port (Hardware) has the issue. Manjaro Gnome is not guilty.
