I have the same problem, but I don’t know a solution. I have the problem
since I replaced my old CPU with a new Ryzen.

Hi,
I didn’t change anything on my laptop or on the ethernet settings etc.
and earlier I didn’t have this problem
It appeared since some weeks and is a new problem.
That’s why I think there should be a solution
Kind regards

Have you by any chance installed/used some virtual machine emulators
recently? Qemu or something similar? The internet suggests the
problematic virbr0 may be created by libvirt which is a dependency of
Qemu.
IIUC, virbr0 is sort of a virtual internet "connection" created
specifically for communication with one's virtual machine(s). Here it
seems Network Manager is confusing virbr0 for the true connection that
it is meant to bring up
Best,
Wojtek

no, I havn’t. I have installed Qemu already long time ago and everything

Hi,
I apologize for my first message, it was not clear.
I should have mentioned to replace <connection name> with the actual
name of the connection (as listed by `nmcli connection`).
Sometimes, my wifi connection (handled by network manager) gets
whimsical and the suggested command fixes it.
However, it does not apply in your case, sorry.

Hi Gottfried,
Sorry, this command I suggested (`sudo herd restart network-manager`)
was incorrect. The one given by Paren, `sudo herd restart networking`,
is the right one. Try it.

And I assume you already tried re-plugging it?

Arnaud surely wanted you to replace the "<connection name>" part with
the name of an actual connection on your system.
It seems a bridge (aka a virtual connection) under the name "virbr0"
somehow got created on your system. You could try running
nmcli connection down virbr0 &&
nmcli connection up enp53s0
Alternatively, you could even try
sudo ip link del virbr0
to remove this mysterious virtual bridge instead of disabling it
> There is no possibility shown to enable networking again, no button

Not even a button to turn it off? Perhaps there's at least some helpful
context menu available when right-clicking?

I guess it tells you that WiFi is enabled in software but also that no
WiFi hardware is available to Network Manager. Which means it's not
going to use WiFi anyway. If you want to also disable WiFi in software
(only practically useful when Network Manager has access to some WiFi
hardware), you can run
nmcli radio wifi off
as per nmcli's manpage.
