LABEL DESCRIPTION
Enable DCS This field is available when you set Channel Selection to DCS.
Client Aware
Select this to have the Zyxel Device switch channels only when there are no clients
connected to it. If there is a client connected, the Zyxel Device will not switch channels but
generate a log. The Zyxel Device tries to scan and switch channels again at the end of the
specified time interval or at the scheduled time.
If you disable this then the Zyxel Device switches channels immediately regardless of any
client connections. In this instance, clients that are connected to the Zyxel Device when it
switches channels are dropped.
2.4 GHz Channel This field is available when you set Channel Selection to DCS.
Selection Method
Select how you want to specify the channels the Zyxel Device switches between for 2.4
GHz operation.
Select auto to have the Zyxel Device display a 2.4 GHz Channel Deployment field you can
use to limit channel switching to 3 or 4 channels.
Select manual to select the individual channels the Zyxel Device switches between.
Note: The method is automatically set to auto when no channel is selected or
Channel ID This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel
Selection Method to manual.
Select the channels that you want the Zyxel Device to use.
2.4 GHz Channel This is available when you set Channel Selection to DCS and the 2.4 GHz Channel Selection
Deployment
Method is set to auto.
Select Three-Channel Deployment to limit channel switching to channels 1,6, and 11, the
three channels that are sufficiently attenuated to have almost no impact on one another.
In other words, this allows you to minimize channel interference by limiting channel-
hopping to these three "safe" channels.
Select Four-Channel Deployment to limit channel switching to four channels. Depending
on the country domain, if the only allowable channels are 1-11 then the Zyxel Device uses
channels 1, 4, 7, 11 in this configuration; otherwise, the Zyxel Device uses channels 1, 5, 9, 13
in this configuration. Four channel deployment expands your pool of possible channels
while keeping the channel interference to a minimum.
Enable 5 GHz DFS This field is available only when you select 5G in the 802.11 Band field, set Channel
Aware
Selection to DCS and set 5 GHz Channel Selection Method to auto.
Select this if your APs are operating in an area known to have RADAR devices. This allows
the Zyxel Device to downgrade its frequency to below 5 GHz in the event RADAR signal is
detected, thus preventing it from interfering with that signal.
Enabling this forces the AP to select a non-DFS channel.
5 GHz Channel Select how you want to specify the channels the Zyxel Device switches between for 5 GHz

operation.
Select Auto to have the Zyxel Device automatically select the best channel.
Select manual to select the individual channels the Zyxel Device switches between.
Note: The method is automatically set to auto when no channel is selected or
Channel ID This field is available only when you set Channel Selection to DCS and set 5 GHz Channel
Selection Method to manual.
