To surf the Internet or send and receive e-mail messages, you must have configured an Internet connection with YaST. Depending on your environment, in YaST select whether to use NetworkManager. In GNOME, you can then establish Internet connections with NetworkManager as described in Abschnitt „Verwenden des GNOME NetworkManager-Miniprogramms“ (Kapitel 10, Verwenden von NetworkManager, ↑Start).
For a list of criteria to help you to decide whether to use NetworkManager, refer to Abschnitt „Anwendungsbeispiele für NetworkManager“ (Kapitel 10, Verwenden von NetworkManager, ↑Start).
