When I roam from one floor to another with my Staff Device while connected to Staff WiFi I am facing this issue.
Each floor access switch is configured different VLAN for STAFF WiFi , So when I roam from one floor to another I get different IP address from the VLAN subnet for that particular floor .
Well THE PROBLEM is when some users go to different floor they are not getting new IP address and getting error ( No internet connection ).
Couple of time users need to tern off and on WiFi on the device they after few minutes they get WiFi connection and new IP address.
While I checked log for that device on the Cisco ISE, I can see error as below.
WLC is Cisco 5520
AP is AIR-CAP2702I-E-K9
Please can some one advise how to solve this issue

Resolution :Verify known NAD or supplicant issues and published bugs. Verify NAD and supplicant configuration.
Root cause :Endpoint started new authentication while previous is still in progress. Most probable that supplicant on that endpoint stopped conducting the previous authentication and started the new one. Closing the previous authentication.""""
