We have a network with 80AP's and vSCG.
We see a lot of client Roaming but also a lot of client disconnect-join sequences where a mobile client disconnects from 1 AP and joins to a neighbour AP within 2 sec.
The log shows: disconnectReason=3. Also it shows Instantaneous rssi=0 or Instantaneous rssi=12.
We would expect the client to Roam instead of Disconnect and Join. Overall Wifi coverage is 65db or better. The clients have a internal Roaming treshhold set to 65db.
Why do we see this disconnect-join sequences and what means Instantaneous rssi=0?
