The wireless priority determines which wireless network to connect to over the other, if multiple networks that you previously connected to are available. If there is an unknown address, broadcast, or multiple interfaces within the same subnet, this is where you tell windows which interface to send to first. That, as far as I understand, is only concerned with where to forward packets on which interface first. That changes the priority of physical connections and wireless connections independently. The answer about changing the connection priority appears to be wrong.
