If you have a Radius server you could go for this setup https://documentation.meraki.com/MR/Encryption_and_Authentication/Enabling_MAC_based_access_control_on_an_SSID Or if you do not have a Radius server or want an easier manual setup you could create a splash page and manually add know clients to the whitelist. https://documentation.meraki.com/MR/Splash_Page/Using_a_Sign-on_Splash_Page_to_Restrict_Wireless_Access_by_MAC_address edit: there isn't really one right way of doing this so just pick the one you are the most comfortable with. If you have system manager licenses for your clients you could even secure the SSID via Sentry Enrollment. If i'm not mistaken Windows devices are supported now.
