I have a couple of clients not able to connect to a wireless network from the Ruckus. They can connect to other networks fine, and other laptops connect to the network fine. Setup is: Ruckus ZoneDirector1106 with 18.104.22.168 build 59 with two AP's. The problem clients have different operating systems. If I duplicate the network and change the authentication from 802.1x-eap to 'open' the clients can connect.
There was a Update for Windows 10 at the end of november which has changed the default TLS-Version. Maybe some of your clients don't have this update, so there won't be a problem. As already said, I'm not pretty sure about that, it's just a suggestion.
Did you try to connect with several users on the same machine?
Thanks for the suggestion. That was my thinking also, but I couldn't find any update that seemed to make a difference. Updates are run automatically, and if they were released in November I doubt that they would still not have run, but I will confirm this. I did try to connect with several different users on the same machine. All those users can connect fine on my machine on the same connection.
