we are using 2 WISMs, with version 4.2.207 and a WCS to control them.
It seemed to work fine for about 2 weeks, and now we detected the following problem in some users. They were connected to the wireless without problems, and then they lost the connection. For authentication we use WPA2, we also use mac-filter.
When they lost the connection we can see the following error:
Client 'mac address' which was associated with AP 'mac address', interface '1' is excluded. The reason code is '4(802.1X Authentication failed 3 times.)'.
Client 'mac' which was associated with AP 'mac', interface '0' is excluded. The reason code is '4(802.1X Authentication failed 3 times.)'.
I also attach an output of the troubleshoot mac address...
Can some help me with this?
