Hi @HyounA , please reinstall Parallels Tools as suggested in this article. If the issue persists, please follow the steps mentioned below:
Check and adjust the virtual machine configuration:
* Network adapter status and existence:
* Go to Configuration > Hardware > Network 0 > Source and make sure the Disconnected checkbox is not marked.
* If Network 0 is not present, please click + sign at the bottom of the configuration window to add a new adapter. Then follow the Creation Wizard.
