I have configured My Aironet 1100 with WPA as follows:
TKIP for Encryption and 802.1x with EAP for authentication, PEAP
And Also ACS v 3.3 as authentication server with MY AP client RADIUS (Cisco Aironet).
My problem from time to time "not fixed" asked to reauthenticate again, i entered my credential, but asked me again "i'm sure that the credential is correct".
My disconnection is not fixed after a period of time, sometimes i have connected for more than 10 hours without any disconnection and sometimes within one hour asked to reauthenticate more than three times.
My AP config.
=============
!
ssid Julia
authentication open eap eap_methods2
authentication network-eap eap_methods2
authentication key-management wpa
accounting acct_methods2
guest-mode
!
Log File after disconnection:
=============================
- Interface Dot11Radio0, Station XXXX.XXXX.XXXX Associated KEY_MGMT[WPA]
- Station XXXX.XXXX.XXXX Authentication failed
- Interface Dot11Radio0, Deauthenticating Station XXXX.XXXX.XXXX Reason: Previous authentication no longer valid
Any comments?
Thanks in advance

If the authentication is successful sometimes, then there is no issue on the authentication parameters. The disconnection may also be due to RF interference. Check if there is RF interference in the surrounding. Alternatively try using a different channel on the AP.
