Ethernet icon showing question mark and staying offline, wifi icon is ok but I am still offline in all applications. Yesterday I had no issue and it does not exist when I boot Windows on the same computer (dual-boot Fedora 39 Gnome and Windows). I tried booting with kernel 6.6.8 and 6.6.6, Gnome and Gnome xorg but it didn’t make any difference.
My command “ping google.com” resulted in this response:
“ping: google.com: Temporary failure in name resolution”

The issue has gone without me doing anything but thank you very much for your support!
The issue re-appeared one day later again, so I had to try your solution anyway - unfortunatelly it lasted just one day. Now I found out that I have the issue also on my other computer connected to the same router. It is running Rhino Linux. So affected are only my both Linux OSes - Windows 11 is not affected… Rhino OS went online after a while without me doing anything. Fedora is still offline.
The same router works flawlessly on Windows 11 (dual boot Windows 11 & Fedora). I never needed before to configure a public DNS provider so I have no idea how to do it right now.
For your information, I found the solution, which helped me, here: Systemd-resolved fails on initial load
