The System - Network Activity page of the Preferences dialog
The System - Network Activity page of the Preferences dialog allows the user full control over network connectivity. Altium Designer uses the Internet and third party servers to connect to Altium Cloud, Altium Vault, suppliers, to search for updates, etc., and it may be desired or necessary to work offline in some situations or environments. You can disable specific network activity or disable all network activity.
The dialog is accessed by clicking Network Activity under the System folder in the main Preferences dialog (DXP » Preferences).
