+```nmcli con down wan-wifi-connection-name
+nmcli con up wan-wifi-connection-name```
+
+If you receive an error message like ```Warning: password for '802-11-wireless-security.psk' not given in 'passwd-file' and nmcli cannot ask without '--ask' option. Error: Connection activation failed.``` the workaround is to include --ask in your nmcli con up command:
+
+```nmcli --ask con up wan-wifi-name```
