Hi,

we deployed a RADIUS wifi network using PEAP with MSChapV2 for authentication (FreeRADIUS server). While it has always worked with all of our Windows 7 clients flawlessly, we are having issues with Windows 8.1 and Windows 10 clients. Connecting works again fine if a local user account is used. As soon as we use a domain-joined account it will not connect.

We are using a certificate signed by our company's custom certificate authority for the RADIUS server. We've verified that the CA is correctly installed and also tried a connection without verification of the certificate.

We are also using the latest available driver from Intel for the wifi card.

Do you have any ideas what the problem might be? Thanks in advance!

Hi,

How about your problem now? According to your description, it seems like user profile problem. Is there any error message when connect to the wifi network failed?

On the other hand, have you installed any other VPN client on your system? If that it is, try to remove it for test.

You can try to perform a Clean Boot to check whether this problem caused by 3rd program or service start with system. Refer to the link below for more details.
