I installed WICD to see if it was a better Network Manager than the regular one, but I didn't like it so I uninstalled it.
Now I have difficulty to reinstall the regular Network Manager in Mint (KDE version).
I tried many different things. I ran:
sudo apt-get install network-manager
sudo apt-get install network-manager-gnome network-manager
And many other things, but nothing worked.
Actually I think the Network Manager is perhaps running in the background because when I run:
nmcli dev
I get: I don't see the Network Manager icon (which I think it's called applet) in System Tray. And strangely enough when I run:
nm-applet
A Network Manager icon (or applet) appears temporary in System Tray BUT that Network Manager is NOT the one I used to have before. So I don't quite understand what is going on...
Otherwise, I was thinking to reinstall manually the Network Manager with .deb packages but I cannot find them here.
Before installing WICD I removed the Network Manager, but I did not remove the config files, perhaps it can be of some help.
My system is:
Kernel: 4.4.0-53-generic x86_64 (64 bit) Desktop: KDE Plasma 5.8.7 Distro: Linux Mint 18.1 Serena
