+          Note that to enable connectivity check, a valid uri must
+          also be configured. The value defaults to true, but since
+          the uri is unset by default, connectivity check may be disabled.
+          The main purpose of this option is to have a single flag
+          to disable connectivity check. Note that this setting can
+          also be set via D-Bus API at runtime. In that case, the value gets
+          stored in <filename>/var/lib/NetworkManager/NetworkManager-intern.conf</filename>
