Thanks, But don't find the some examples in source tree of NM in examples directory. Also I still have the confuse for the connection I have the object path /org/freedesktop/NetworkManager/Devices/0 for WIFI under the bus name org.freedesktop.NetworkManager, and /org/freedesktop/NetworkManager/AccessPoint/15 for this connection
$SERVICE="org.freedesktop.NetworkManager" $CONNECTION="/org/freedesktop/NetworkManager/AccessPoint/15" $DEVICE="/org/freedesktop/NetworkManager/Devices/0" $ dbus-send --system --print-reply --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.ActivateConnection string:"$SERVICE" objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/" Error org.freedesktop.NetworkManager.InvalidService: Invalid settings service name If I try the following, it also have the errors: SERVICE="org.freedesktop.NetworkManagerSystemSettings" CONNECTION="/org/freedesktop/NetworkManager/AccessPoint/15" DEVICE="/org/freedesktop/NetworkManager/Devices/0" dbus-send --system --print-reply --type=method_call --dest='org.freedesktop.NetworkManager' '/org/freedesktop/NetworkManager' org.freedesktop.NetworkManager.ActivateConnection string:"$SERVICE" objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/" Error org.freedesktop.NetworkManager.UnknownConnection: Connection was not provided by any settings service How can I solve this problem?
