After specifying the needed parameters, click the APPLY button.
To disable the function of smart adjustment of Wi-Fi clients, click the DISABLE button.
This parameter is used for calculation of the signal strength upon
which the smart adjustment function goes off. If the signal strength
provided by the 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 access point (router) and
connects to another device. You can specify the values from -50% to
+50%.
Move the switch to the right in order to use multicast traffic for
service data exchange between access points (routers). 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.
Specify the TTL (Time to live) parameter value. The recommended
value is 4.
Specify the address of the multicast group (from the subnet
239.255.0.0/16).
