Wireless AP Overloaded by Stations
A wireless AP has exceeded the number of stations defined in the Expert Threshold. Setting a stations-per-AP threshold can be useful in maintain performance as well as security.
Possible reasons for the event:
If you have defined the maximum number of stations allowed per AP for security reasons, it could mean a security threat is underway. For example, if you have only 10 corporate laptops and want allow for a guest or two, setting a threshold of 12 could alert you to a wardrive or hack attack in progress)
If you have defined a threshold for performance purposes, it could mean that the AP in question needs to moved or upgraded.
