The run down goes like this: 1) Connect to onboarding SSID 2) Run JoinNow 3) Authentication Loop on Windows 10 Doing some research into it, there are a couple of things we noticed: a) If we turn off server validation, the Windows 10 device connects fine. b) looking at a packet trace, the device just stops responding to the RADIUS server after the server cert has been pasted to the client. c) we have to re-install the wireless driver on the device to be able to get the device working again. d) Our old CloudPath installation appears to be resulting in the same thing. We are running EAP-TTLS/EAP-PAP here. I was curious if anyone else was seeing issues with Windows 10 devices following the latest patching from Microsoft. -- Charles Rumford Senior Network Engineer ISC Tech Services University of Pennsylvania OpenPGP Key ID: 0x173F5F3A (2018/07/05) ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.

RE: [WIRELESS-LAN] Issues with Windows 10
We had a cert issue a few years back. Our intermediate cert authority got a root cert of their own and it started getting deployed with major operating systems. Devices that had the new root cert wouldn't use the old root cert, so server validation failed. I don’t see how reinstalling the wireless driver would correct that problem, so I'm not saying you have the same issue. It's just something to check for.

From SecureW2: The issue is noticed when the RADIUS server cert is signed by AddTrust External CA Root (Cross signed by USERTrust RSA Certification Authority) and with the recent windows 10 update. We are looking into this and should be able to provide you an update.

Re: [WIRELESS-LAN] Issues with Windows 10
Hi Charles, What do you mean by "we ended up configuring all of the intermediate certs"? Do you mean you are now pushing all certs down to the client during the JoinNow process? We are also running EAP-TTLS/PAP with JoinNow with a cross-signed double intermediate cert. I haven't heard of any issues yet but want to get in front of any that might crop up..

Re: [WIRELESS-LAN] Issues with Windows 10
We didn't know that the mechanism to validate a certificate wasn't really that strict and thought it was a good idea. If we had to do it over, it would totally be a self signed cert with a long expiration date. Also we had never dealt with intermediates and changing roots due to expiration for the first several years. Thanks, Joseph B.

Re: [WIRELESS-LAN] Issues with Windows 10
Because Macs and iPhones allow you to manually verify the certificate hash, which is easier and equally secure to a supplicant utility, so we also support that avenue for configuration. However, if you don't have a public-CA-signed certificate, they display the words "Not Trusted" in red bold letters during the certificate verification process.
