@Gumbyok, my computer always connects to this SSID but other computers if it blocks and another does not.
It seems that is how you comment.
Do you mean that only the policy will apply to the equipment that has never connected to that SSID ??? or that they have never connected to the Meraki equipment (that is, in another SSID or LAN) ???
Is there any way to delete my MAC from Meraki so that I can apply the policy ???
Well, even though I have deleted my laptop's Wi-Fi network, it still connects.
