Question

Hello toaster users!
I use SuseStudio(susestudio.com) to build distributions, I have some questions about OpenSuse KDE.
1) What is the name of the Wi-Fi extension?
It's just that the standard OpenSuse KDE package does not see my Wi-Fi router, although other OSes (Ubuntu/Windows) work fine with Wi-Fi.
2) What is the name of the extension for connecting the Internet via cable?
The same. The standard NetWork-Plugin does not help me either with the first or with the second question.
3) What is the name of the extension so that the operating system has only a KDE theme similar to Windows (With a round button and windows)
In order to have one KDE theme.
Thank you very much for your attention and thanks in advance for your replies!
