+-----------------------------------------------
+
+The 'iwconfig ethX sens XX' command will not set the signal sensitivity
+threshold, as described in iwconfig documentation, but rather the number
+of consecutive missed beacons that will trigger handover, i.e. roaming
+to another access point. At the same time, it will set the disassociation
+threshold to 3 times the given value.
