NetworkManager provides its own command-line tool - nmcli. You can use it for 
most of controlling stuff on the command line.

Deactivating a connection:
nmcli con down id "your connetcion name"

or disconnecting an interface:
nmcli dev disconnect iface wlan0

Info:
* man nmcli
* Comparison of cnetworkmanager x nmcli commands:
