WLAN disconnection!

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- Interface Dot11Radio0, Deauthenticating Station XXXX.XXXX.XXXX Reason: Previous authentication no longer valid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

Re: WLAN disconnection!

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.

Re: WLAN disconnection!

Are you performing broadcast key rotation? Are you using vlans?
