After specifying the needed parameters, click the APPLY button.
To disable the function of smart adjustment of Wi-Fi clients, click the DISABLE button.
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.
Specify the address of the multicast group (from the subnet
239.255.0.0/16).
The maximum time period (in seconds) during which the access
point (router) stores data on the signal strength of the client located
on its coverage area.
The signal strength upon which the access point (router) starts
scanning other devices in order to find a device with a higher signal
level.
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 access point (router). You
can specify the values from -50% to +50%.
The signal strength upon which the access point (router) 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.
