How should René enable the Wi-Fi menu in the menu bar if it's missing?

To enable the Wi-Fi menu in the menu bar, opening System Preferences and enabling the Wi-Fi status is the correct approach. This option allows the user to directly access network settings, where they can manage various connections, including Wi-Fi. By checking the option to show Wi-Fi status in the menu bar, René can ensure that the Wi-Fi icon is visible and provides quick access to network-related functions.

Using System Preferences is a straightforward method that offers user-friendly controls, making it easy to adjust settings and see the changes reflected immediately in the menu bar. This is a typical process for managing menu bar icons on macOS, ensuring users can customize their interface for convenient access to the features they use most often.
