I have a problem authenticating with Cisco Aironet 1200 access point. I
have valid certificates on my laptop and on Freeradius.
This is the output on AP:
Interface Dot11Radio0, Deauthenticating Station 001e.4c8c.8406 Reason:
Sending station has left the BSS
Interface Dot11Radio0, Station NBD7FB3G3J 001e.4c8c.8406 Associated
KEY_MGMT[NONE] 3
Interface Dot11Radio0, Deauthenticating Station 001e.4c8c.8406 Reason:
Previous authentication no longer valid
This is what I get on freeradius:
