Retrieve Wireless Capabilities
The following steps describe how to retrieve the 802.11 subparagraph capabilities of the wireless interface.
1. Retrieve the instance of CIM_WiFiPort, where the “DeviceID” key equals “WiFi Port 0”.
2. From the CIM_WiFiPort instance, traverse the CIM_ElementCapabilities association to find the instance of CIM_WiFiPortCapabilities.
3. Examine the SupportedPortTypes property to determine the 802.11 modes that the port supports: 802.11a, 802.11b, 802.11g, 802.11n or other.

# Create a reference to the AMT_PublicKeyManagementService instance.
$wifiPortRef =$wsmanConnectionObject.NewReference("SELECT * FROM CIM_WiFiPort WHERE DeviceID='WiFi Port 0'")
$elementCapabilitiesRef =$wsmanConnectionObject.NewReference("CIM_ElementCapabilities")
$elementCapabilitiesRef.AddSelector("ManagedElement",$wifiPortRef)
# Traverse to the CIM_ElementCapabilities instances that are connected to the CIM_WiFiPort instance.
foreach($elementCapabilitiesItem in$elementCapabilitiesRef.Enumerate("http://schemas.dmtf.org/wbem/wsman/1/wsman/SelectorFilter",$null))
{
# For each instance, check if it is associated to the CIM_WiFiPortCapabilities instance.
if ($elementCapabilitiesItem.Object.GetProperty("Capabilities").IsA("CIM_WiFiPortCapabilities"))
{
# Get the CIM_WiFiPortCapabilities object using its EPR.
$wifiPortCapabilitiesInstance =$elementCapabilitiesItem.Object.GetProperty("Capabilities").Ref.Get()
$supportedPortTypes =$wifiPortCapabilitiesInstance.GetProperty("SupportedPortTypes")
}
}
4. Retrieve the instance of CIM_IEEE8021xCapabilities, where the “InstanceID” key equals “Intel(r) AMT:IEEE 802.1x Capabilities”.
5. Examine the SupportedAuthenticationProtocols property to determine the protocols supported by the associated endpoint: EAP-TLS, EAP-TTLS/MSCHAPv2, PEAPv0/EAP-MSCHAPv2, PEAPv1/EAP-GTC, EAP-FAST/MSCHAPv2, EAP-FAST/GTC, EAP-MD5, EAP-PSK, EAP-SIM, EAP-AKA and/or EAP-FAST/TLS.

$ieee8021xCapabilitiesRef =$wsmanConnectionObject.NewReference("SELECT * FROM CIM_IEEE8021xCapabilities WHERE InstanceID='Intel(r) AMT:IEEE 802.1x Capabilities'")
$ieee8021xCapabilitiesInstance =$ieee8021xCapabilitiesRef.Get()
$supportedAuthenticationProtocols =$ieee8021xCapabilitiesInstance.GetProperty("SupportedAuthenticationProtocols")
6. Retrieve the instance of CIM_WiFiEndpointCapabilities, where the “InstanceID” key equals “Intel(r) AMT:WiFi Endpoint Capabilities”.
7. Examine the SupportedAuthenticationMethods property to determine the set of IEEE 802.11 authentication methods supported by the associated WifiEndpoint: Open System, Shared Key, WPA PSK, WPA IEEE 802.1x, WPA2 PSK, WPA3 SAE, and WPA2 IEEE 802.1X.

Support for PSK was removed in Intel AMT release
11.0. |
8. Examine the SupportedEncryptionMethods property to determine the set of IEEE 802.11 encryption methods supported by the associated WifiEndpoint: WEP, TKIP, CCMP, or None.

$supportedAuthenticationMethods =$wifiEndpointCapabilitiesInstance.GetProperty("SupportedAuthenticationMethods")
$supportedEncryptionMethods =$wifiEndpointCapabilitiesInstance.GetProperty("SupportedEncryptionMethods")
