Reason:802.11 Association failed repeatedly. ReasonCode: 2

Unanswered Question
Nov 2nd, 2009


I have a costumer that has a wireless network with a WLC 4400 (ver and several Aironet APs (1250 version 12.4).

He also has a Wireless IP Phone. The IP Phone loses the communication with the LAN very often.

In the WLC logs we can see the following error:

Client Excluded: MACAddress:00:24:c4:55:11:58 Base Radio MAC :00:25:84:89:fe:20 Slot: 0

User Name: unknown Ip Address: Reason:802.11 Association failed repeatedly. ReasoCode: 2

In the documentation I did not see any information regarding this error, anybody has a clue about the meaning of this error? How can I fix it?

Best Regards,

Artur Pinto

I have this problem too.

If memory serves correct reason code 2 means that a duplicate IP address was detected.

Can anyone confirm that reason code '2' refers to duplicate IP addresses?

If this is true it would explain a lot for some of my own issues.

ReasonCode 2: Previous authentication no longer valid (Client associated but not authorized).
