This message appears with the Workgroup Bridge or Repeater or an individual client when they associate or reassociate with the access point.
This message indicates frequent disconnection and reassociation of a client device. As a workaround
1. Change the channel number to avoid potential RF interference issues.
2. Check for the authentication configured
3. Either downgrade to a previous version or upgrade the image of the client device.
Note: Increase the client timeout on the access point to make the client devices stay associated for a longer time. and see of ot makes the difference.
