Parameter Description
Use multicast for 
service data exchange
Move  the  switch  to the right in   order  to  use multicast traffic for 
service   data   exchange  between   access  points  (routers,  extenders). 
This   setting   is   needed   if   the   devices   which   support   the   smart 
adjustment function are located in different subnets. If the switch is 
moved   to   the   right,   the  Multicast   TTL  and  Multicast   group 
address fields are displayed on the page.
If the switch is moved to the left, broadcast traffic is used for service 
data exchange.
Multicast TTL
Specify the TTL (Time to live) parameter value. The recommended 
value is 4.
Multicast group 
address
Specify   the   address   of   the   multicast   group   (from   the   subnet 
239.255.0.0/16).
2.4 GHz / 5 GHz
Maximum time of 
storing data
The maximum time period (in seconds) during which the extender 
(access point) stores data on the signal strength of the client located 
on its coverage area.
Minimum level of 
connection quality
The  signal  strength  upon which the extender  (access   point) starts 
scanning other devices in order to find a device with a higher signal 
level.
Dead zone
This parameter is used for calculation of the signal strength upon 
which the smart adjustment function goes off. If the signal strength 
provided by another device is less than the sum of the  Minimum 
level of connection quality field value and the Dead zone field 
value, then the client disconnects from the extender (access point). 
You can specify the values from -50% to +50%.
Threshold value of 
connection quality
The   signal   strength   upon   which   the   extender   (access   point) 
disconnects the   client   from its wireless network regardless of   the 
signal levels of other devices. This value should not be greater than 
the value specified in  the field  Minimum  level of connection 
quality.
After specifying the needed parameters, click the APPLY button.
To disable the function of smart adjustment of Wi-Fi clients, click the DISABLE button.
