If available on the system, Cockpit uses NetworkManager and the DBus APIs it provides to interact with the system's network configuration.
For non root users, NetworkManager controls access to its APIs via Policy Kit and a user logged into Cockpit will have the same permissions as they do from the command line.
To perform similar tasks from the command line, use the nmcli command:
$ nmcli general status STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN connected full enabled enabled enabled enabled
Devices marked as "not managed" with the
