You can't do plain MAC auth with wireless - you must use EAP.

You could check mac address as well (but really, these days it's
probably not worth it), but not on its own.

If you want to authenticate the device then EAP-TLS is the way to
go. But at least it won't break when the devices decide to change
their MAC addresses, as so many are starting to do randomly these
