Default and go to
Step 3 In the Minimum RSSI field, enter a value for the minimum received signal strength indicator (RSSI)
required for the client to associate to an access point. If the client's average received signal power dips
below this threshold, reliable communication is usually impossible. Therefore, clients must already have
found and roamed to another access point with a stronger signal before the minimum RSSI value is
reached.
Range: –80 to –90 dBm
Default: –85 dBm
In the Hysteresis field, enter a value to indicate how strong the signal strength of a neighboring access

point must be in order for the client to roam to it. This parameter is intended to reduce the amount of
"ping-ponging" between access points if the client is physically located on or near the border between
two access points.
Range: 2 to 4 dB
