Enabling NetworkManager

On laptop computers, NetworkManager is enabled by default. However, it can be at any time enabled or disabled in the YaST Network Settings module.

Run YaST and go to Network Devices+Network Settings.
The Network Settings dialog opens. Go to the Global Options tab.
To configure and manage your network connections with NetworkManager, select User Controlled with NetworkManager.
Click OK.
After choosing the method for managing network connections, set up your network card using automatic configuration via DHCP or a static IP address or configure your modem (for dial-up connections, use Network Devices+Modem). To configure an internal or USB ISDN modem, select Network Devices+ISDN. To configure an internal or USB DSL modem, select Network Devices+DSL.
Find a detailed description of the network configuration with YaST in Section “Configuring a Network Connection with YaST” (Chapter 21, Basic Networking, ↑Reference) and Chapter Wireless LAN (↑Reference).

After having enabled NetworkManager, configure your network connections with the NetworkManager as described in Section 5.3, “Configuring Network Connections”.

If you want to deactivate NetworkManager and control network the traditional way, choose the Traditional Method with ifup option in the Network Setup Method field.
