In an effort enhance our security, we have enabled WPA2-Enterprise Wireless and 802.1x Wired to our network infrastructure.   The minimum certificate that is needed to access is the 802.1x CA Certificate which needs to be installed at the “Computer” & “User” level as Trusted Root.  There are issues with Windows 7 and 802.1x that require Certificate Validation against known Roots, Windows 10 is more forgiving.
