Wenn ich über den NetworkManager (KDE) eine "Wi-Fi (Freigegeben)"-Verbindung erstellen möchte, wird dieser zwar erstellt, nur kann sich kein Client damit verbinden. Die Clients bekommen keine IP Adresse zugewiesen.
Im Log vom NetworkManager meldet dnsmasq einen Fehler er könnte eine Lease-Datei nicht öffnen wegen fehlender Berechtigung. Allerdings befindet sich solch eine Datei überhaupt nicht im Ordner vom NetworkManager.
