Hi,
I installed openSUSE on my desktop a month ago and I'm using KDE plasma 5 as my desktop environment. The problem is that the network applet isn't showing properly in the system tray...
Firstly, NetworkManager wasn't even running so I started it and added it to boot up. Then after some research I found that a package called plasma-nm should be installed. After checking it was, I decided to reinstall it and restart the computer... still nothing shows up. when I hover the mouse above (there is no icon by the way) a tooltip shows up and say that i'm connected, nice, but when I click, there's just a 'blank' widget.
The network works just fine, but that really bugs me and I don't know what is wrong.
Many thanks in advance (I'm not 100% sure if it is the OS or the DE TBH).

The problem may be that openSUSE uses "wicked" by default, not NetworkManager.

Go into YaST->System->Network Settings, switch the network service to "Network Manager Service" in the "Global Settings" tab, and it should work...

Thank you wolfi323 that was it : ) .
