11.2.2 NetworkManager and SCPM
NetworkManager cannot work together with System Configuration Profile Management (SCPM) if
SCPM also manages the network configuration. If you want to use SCPM and NetworkManager at

connections are identified by the name and MAC address of the access point. Using the MAC
address ensures that you cannot use a different access point with the name of your trusted
connection.
If no wired connection is available, NetworkManager scans for available wireless networks. If
multiple trusted networks are found, the most recently used is automatically selected. If all are
untrusted, NetworkManager waits for your selection.
If the encryption setting changes but the name and MAC address remain the same, NetworkManager
attempt to connect, but it first asks you to confirm the new encryption settings and provide any
updates, such as a new key.
In a system with a wireless connection only, NetworkManager does not automatically start the
connection during boot. You must log in first to establish a connection. If you want to make a
