I have a costumer that has a wireless network with a WLC 4400 (ver 188.8.131.52) 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: 10.70.18.113 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?
