Maybe remove/disable the built in WiFi adapter in the computer and use a USB WiFi adapter? Then it's just a matter of giving them the WiFi adapter or not. Most laptops have fairly easily removable WiFi cards under a cover on the back. Some laptops and most desktop motherboards you can disable the built in WiFi adapter in bios. You can also disable the WiFi adapter under network settings, but not sure if a non-administrator user couldn't just re-enable it.
