Hi, in case you have plasma-nm installed, cmst (connman) shouldn't have been installed at all.
Lxqt metapackage recommends cmst (connman) or nm-tray (network-manager) or network-manager-gnome (network-manager) or plasma-nm (network-manager) or wicd (wicd-daemon). In case you have network-manager without plasma-nm installed, avoid the lxqt metapackage, or add network-manager to its recommends. Cheers, Amy
