It seems YaST is not able to change network settings because NetworkManager controls this. Maybe you can include a button to directly start this NetworkManager from this message, then I don’t have to search for it.
The Ethernet network card is not working. I don’t know if this is because of a miss configuration or there is an issue with the driver. I’m using DHCP and I don’t know what there can be wrong in configuration for it because there is nothing to do for DHCP. The network chip is a Realtek RTL8125B 2.5Gb with B whereas YaST shows it as 8125 without a B.
I do not quite understand here what you want. In YaST > System > Net work Settings, maybe the first thing you choose is between Eicked or NetworkManager. When NM is chosen (you could have done that during installation, but you have done it), YaST reminds you of that when you nevertheless try to change the Wicked configuration (which is useless).
NetworkManager (the server program) should be started “automatically” at boot when the choice for it is made. I doubt a special button is needed for that (and I do not understand what you searched for and where you found it).
And AFAIK, the user that starts a GUI will be presented by an icon for the client part, but that depends on de desktop chosen.
About Network Settings and Network Manager:
I see that the network is not working and so I look for the network settings like I do with Windows. But YaST did not show me all network settings instead it reports that NM controls the network. From post #4 I understand that NM is a server process without a GUI. So which GUI is used to check the network settings?
During installation I only change settings which are necessary, e.g. set network to DHCP. Most settings are YaST default. I don’t think that I have change between NM and Wicked when YaST not told me to do.
I think you need to provide a little more information for folks around to help." The Ethernet network card is not working." Is a bit on the sparse side.
First thing: Is it showing any “life” by the LED next to the plug? The MB manual usually shows some info about the LED “code”. If there is nothing, the card may not be working indeed. Otherwise, there’s hope.
What DE are you using? In KDE you should see the symbol of network applet in the starter bar down right. Click on it and see what is available.

Basically the saying is: when going to Unix/Linux, forget evrything you learned with MS Windows rotfl!
The GUI client in this case starts from the NM icon in a user desktop session, look for the icon in the desktop panel. NM is made for “travel around” computers (like laptops that you take with you, thus not laptops/desktops that are always on the same place, cable or wifi) to give the end-user control over the network connection. After all when wandering around you encounter different networks at the same time and the user is not happy when he has to ask the system manager (the one that knows the root password) to re-configur the network all the tine.
There is however also a CLI NM client.
When the device is a laptop (or when the installer guesses it is), NM will be chosen as default. Of course one could have taken different, but I understand that, specially at the first installation, one goes for default settings. After all, when the installer would have asked you “wicked or NM” would you have known what is best?
