Wireless high reassociations
Reassociations occur when an already associated station senses that another access point that has a stronger signal is within range. This happens when physically moving the station (i.e., "roaming"), or when the RF interferences in the surrounding environment change (for example, somebody turns on a microwave in the break room).
Possible reasons for this event:
A high number of reassociations at a site where you know few stations are physically moving around can indicate that your placement of APs and stations is not optimized; if a station is situated between two or more access points from which it is receiving very weak signals, it will potentially cycle through reassociating with all the access points within range.
RF interference is causing affected systems to disassociate/reassociate.
