Windows 10 802.1x wireless authentication fails due to "Dynamic key exchange did not succeed within configured time"

[ngmanchester]

Hi. Our office has installed a couple of new Cisco 2700 Autonomous Access Points and we are trying to setup EAP 802.1x authentication to our laptops, so we can have a Wireless LAN.


The access points back the authentication off to Cisco ISE, which does a machine and user authentication against Active Directory. Cisco ISE shows that authentication succeeds and a Radius Access-Accept message is returned back to the AP. The AP logs show that the Radius Access-Accept message is received.
"RADIUS: Received from id 1645/238 X.X.X.X:1645, Access-Accept"


When trying to connect to the Wireless on our laptops we enter our username/password and we get a "Unable to connect to network" message.

Note, we can connect normally using a different SSID that is WPA2. Our drivers are up to date.

Windows Event Logs show this sequence:

Reason: Dynamic key exchange did not succeed within configured time

I cannot find anything to think why this might be the case and not a lot online when I have a look about "Dynamic key exchange did not succeed within configured time". I am using the default Windows wireless settings, and WPA2 is fine.


Any help would be appreciated.
