I have following issue but I do not know were I can find useful logs to understand what is going on.
My machine is a very standard Gigabyte Mainboard with integrated Ethernet. Only one NIC is present on the system. The issue started about 3 month ago, I always wanted to investigate but I am too annoyed now, so I really want to solve it.
Take a typical start up: the machine is on a dlan Ethernet were a Devolo 1200 (with a small OpenWRT like OS running on it) is managing the Ethernet interface. When I start up, the system (with wicked as network setup, there is no WLAN on the machine) boots fine. But when arriving at the Plasma desktop you have no network. If you try to restart networking services (e.g. sudo rcnetwork restart) it does but you do not have network. I also tried to restart every wicked service in yast but no network and no error log.
But if you simply reboot the machine all works as expected.
Now I tried this also without a graphical user session, it is the same, so the issue is IMO not bound to Plasma. I thought it might be that this is a timeout with the dlan being in energy saving at the first bood and awaken at the second. But wouldn't wicked wait until the interface has an address? Wouldn't it complain logging clearly in journalctl? Anybody else in the past encountered such an issue?
I would investigate in a console before plasma login. Ie, ctrl-alt-f1, login as root, then find out what exactly is failing. Can you ping the router by IP number? If yes, then investigate DNS and routing. Ping 8.8.8.8, and ping google.com, for instance. If not, is interface up? check logs.
