Re: Sometimes failing EAP authentication in Windows 11 and WiFi

Thanks for the hint regarding the CA validation (i.e. that the client does not trust the RADIUS's certificate and not vice-versa). That helped a lot. In the meantime, I found out what was missing. In the WiFi configuration in Windows 11 you have to specify the fingerprint of the CA used to issue the FreeRADIUS server's certificate: The path in Windows's WiFi configuration XML file is \WLANProfile\MSM\Security\OneX\EAPConfig\EapHostConfig\Config\Eap\EapType\ServerValidation At this location, you need to specify the fingerprint similar to the following: <TrustedRootCA>xx xx xx xx xx ... xx </TrustedRootCA> As soon as this node is there, the WiFi connection is working on my side. Maybe, this can be helpful for anyone else, too... Tom
