Bernard,

All other clients (Ubuntu 22.04, Win11) on the network do not exhibit this feature (bug?). Taking down (reset) the network is very drastic.

Manfred,

The network is wired, not wireless.

The problem is random and intermittent. It occurred yesterday for the first time in many months.

This morning, on the users screen, just after boot, the problem occurred again for about 1 second. Then the icon filled out and the ? disappeared.

Sorry for wrongly assuming that it is wireless, but there are much more wireless problems than with wired networking.

I would not care too much about the situation in the first few seconds after booting.

In case that the icon becomes greyed out again, can you run the command
sudo dmesg | tail -n 30
to check whether there are any system messages related to the problem?

After a second boot, the problem appeared and did not disappear. It is constant. The web is available.

Here is the dmesg output:

I do not see anything related to networking, except success messages ("eno1: NIC Link is Up 1000 Mbps ...").

Do you advise that I open a bug?

Of course you are free to create a bug report. Yet I am not even sure which package you should select as the target. Is it network-manager or just the network applet?

Questions are kept open for 15 days.

I will give the community more time to reflect on this strange bug.

If the internet works...why care?

If a critical gauge on your dashboard fails, someday you might crash the car.
