Hi everyone, I have an issue with user's bouncing while connected to an access point (1130AG). When I looked at the log this is what I found. I have no idea what it means, if any.

Apr 18 14:43:23.502 GMT: %DOT11-4-CKIP_REPLAY: CKIP SEQ replay was detected on a packet (SEQ 0x6) received from 0014.a54d.5566.

Apr 18 14:43:26.862 GMT: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0014.a54d.5566 Reason: Sending station has left the BSS

The IOS running on the AP's is Version 12.3(11)JA1

I would appreciate any imput.

Thank you.

Looking at the "CKIP SEQ ", I think some replay attack being held on your network. CKIp is a layer 2 encryption protocol used in wireless. It is cisco proprietory. It maintains sequence numberbased data integrity. Here, I think the same sequence number is used again. So, replay attack is detected.
