hi im fairly new to Linux have worked on a server or 2,but recently switched over completely from windows
i'm having problems with the plasma-NM, the icon is missing 1st of all and even if i set up a wireless connection in the connection settings it doesn't coronet
im using Debian bullseye with KDE plasma
i have uninstalled Plasma-NM and Re-Installed it restarted no luck

any Thoughts

Debian Bullseye. Did you get the non-free iso? Anywho, if you want a debian stable with kde try running a, for example, MX kde live and check if you have the same prob.
