In the «Advanced» section, you can configure advanced device’s radio interface parameters.
OBSS Coexistence –
automatic channel bandwidth reduction when the air is loaded. When the flag is set, the
mode is enabled;
DFS Support
– dynamic frequency selection mechanism. The mechanism demands wireless devices to
scan environment and avoid using channels which coincide with radiolocation system's channels at 5 GHz:
Disabled
– the mechanism is disabled. DFS channels are not available for selection;
Enabled
– the mechanism is enabled;
Forced
– the mechanism is disabled. DFS channels are available for selection.
Short Guard interval
– support for Short Guard interval. Access point transmits data using 400 ns Guard
interval (instead of 800 ns) to clients which also support Short GI;

If the 'Use Limit channels' list contains a channel that is not available for selection, it will be marked in
grey. In order for the new configuration to be applied to an access point, only available (blue highlighted)
channels must be specified in the 'Use Limit channels' list.
Example.
No settings have been made on the access point yet, Radio 1 is set to 20 MHz 'Channel
Bandwidth' by default, and channels are specified in the 'Use Limit Channels' list: 36, 40, 44, 48.
Suppose the parameter 'Channel Bandwidth' is set to 40 MHz. When you change this parameter from 20
MHz to 40 MHz, the following happens:
the 'Primary Channel' parameter becomes available for editing and the default value is 'Upper';
channels 36 and 44 in the 'Use Limit Channels' list changes its color from blue to gray.
If you change the 'Channel Bandwidth' parameter to 40 MHz and do not remove the 'grey' channels from
the list, then when you click on the 'Apply' button in the browser an error will appear – 'There are errors in
data. Changes was not applied'. Accordingly, the access point configuration will not be changed. This is
due to the fact that channels in the 'Use Limit Channels' list that are highlighted in grey do not fit the
definition 'Primary channel' = Upper.
