nmcli networking [command]

nmcli networking controls the overall networking state managed by NetworkManager. It provides a master switch to enable or disable all network interfaces at once.The connectivity states are:- full: Connected with full internet access- limited: Connected to a network but no internet (captive portal, firewall)- portal: Behind a captive portal requiring login- none: No network connectionThe connectivity check actively probes connectivity by accessing a known URL, while without "check" it reports the cached state from the last probe.

Disabling networking affects all NetworkManager-managed connections but not interfaces managed by other tools. The connectivity check depends on network accessibility to connectivity check servers (configurable in NetworkManager.conf). Some networks block these probes.
