Windows

This guide is applicable for both scenarios: using user- or device-type certificates for WiFi authentication.

Configuration steps

1. Log in to Microsoft Intune

2. Navigate to Devices and subsequently Configuration profiles

3. Then click Create > New policy

4. As Platform select Windows 10 and later

5. Search the Profile type templates for Wi-Fi and select it

6. Click Create and provide a descriptive name and optional Description

7. As Wi-Fi type select Enterprise

8. Enter your SSID. The Connection Name can assume the same name.

9. Configure the Authentication Method to User if you want to use user-type certificates for authentication or Machine if you would like to use device-type certificates for authentication.

10. Then for EAP type choose EAP - TLS

11. Next, as Certificate server names add the

    • Subject Alternative Name (SAN)

    • and Common Name (CN) (only the value, without CN=)

    of your active RADIUS Server Certificate. Those properties can be found by expanding the active server certificate and copying the relevant values. If the SAN and the CN values are identical, you need to add the server name only once.

Please consider, that the common name is case-sensitive.

1. For the Root certificates for server validation select the Trusted certificate profile you have previously created for the RADIUS Server Certificate.

2. Under Client Authentication select SCEP certificate as Authentication method

3. Finally, Client certificate for client authentication (Identity certificate) select the SCEP profile you would like to use for authentication.

   All other settings can be configured according to your own needs and preferences.

Fast roaming

These are optional settings.

For a (usually) better experience when roaming between access points, we recommend enabling the following Fast roaming settings in the WiFi profile:

Enable pairwise master key (PMK) caching	Yes	Defines whether Pairwise Master Key (PMK) caching is to be used by this profile to connect to a WLAN.
Maximum time a PMK is stored in cach	720	Defines the length of time, in minutes, that a Pairwise Master Key (PMK) cache will be kept.
Maximum number of PMK's stored in cache	128	Defines the number of entries in the Pairwise Master Key (PMK) cache on the client.
Enable pre-authentication	Yes	Defines whether pre-authentication will be used by the client
Maximum pre-authentication attempts	3	Defines the number of pre-authentication attempts to try on neighboring access points (AP)

For further details on Pairwise Master Key caching, please refer to its specification in IEEE 802.11i.

Important: The reliability and effectiveness of this feature may also depend on the specific implementation by the WAP vendor. In the same cases, customers with PMK caching enabled, have reported frequent access-point toggling although the device's location was static.
