To completely disable Wi-Fi and hide the Wi-Fi icon on ChromeOS devices, you need to modify the "Network" settings in the Google Admin console: * Go to "Device Management" > "Chrome Management" > "Device Settings". * Select the organizational unit (OU) containing the devices you want to manage. * Under "Network", find "Enabled network interfaces" and remove "Wi-Fi" from the list. * Save the changes. This will disable Wi-Fi adapters on the devices and hide the Wi-Fi icon, preventing users from connecting to Wi-Fi networks. Why other options are incorrect: * A. Restricted Wi-Fi Networks: This setting only limits which networks users can connect to, not disable Wi-Fi entirely. * B. Prevent WiMax connectivity: WiMax is a different wireless technology and not relevant to Wi-Fi. * D. Restrict 'Auto Connecting' to Wi-Fi: This only prevents automatic connection to networks but doesn't disable Wi-Fi entirely.
