Hello,
On a wifi installation, some devices seem to lose connectivity sometimes. The interuption is very quick but significant for their applications.
The controller is a Cisco WLC5508 with the release 7.4.100.60 and the access points are Cisco 1242 (with two external antennas) and 1602.
APs are in Flexconnect mode, and SSID security is in WPA2/PSK.
I don't see any problem with my HP laptop, but with Samsung Galaxy Tab or LXE devices the problem is present.
In the message logs, i found this frequently :
*apfReceiveTask: Jul 01 11:50:17.521: #LWAPP-3-INVALID_AID2: spam_api.c:1357 Association identifier 9 for client 00:26:37:d5:fe:ba is already in use by 00:26:37:ed:0f:1a
And this :
*Dot1x_NW_MsgTask_4: Jul 01 10:01:02.144: #DOT1X-3-INVALID_WPA_KEY_MSG_STATE: 1x_eapkey.c:861 Received invalid EAPOL-key M2 msg in START state - invalid secure bit; KeyLen 24, Key type 1, client 00:26:c6:07:98:44
But i'm not sure that these logs occur a connectivity lost.
Is anyone had roaming issues with this configuration?
Thanks by advance for any response.
