LABEL DESCRIPTION
2.4 GHz Channel This field is available when you set Channel Selection to DCS.
Selection Method
Select auto to have the AP search for available channels automatically in the 2.4 GHz
band. The available channels vary depending on what you select in the 2.4 GHz Channel
Deployment field.
Select manual and specify the channels the AP uses in the 2.4 GHz band.
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 check boxes of the channels that you want the AP to use.
Time Interval Select this option to have the AP survey the other APs within its broadcast radius at the end
of the specified time interval.
DCS Time Interval This field is available when you set Channel Selection to DCS.
Enter a number of minutes. This regulates how often the AP surveys the other APs within its
broadcast radius. If the channel on which it is currently broadcasting suddenly comes into
use by another AP, the AP will then dynamically select the next available clean channel or
a channel with lower interference.
Schedule Select this option to have the AP survey the other APs within its broadcast radius at a
specific time on selected days of the week.
Start Time Specify the time of the day (in 24-hour format) to have the AP use DCS to automatically
scan and find a less-used channel.
Week Days Select each day of the week to have the AP use DCS to automatically scan and find a less-
used channel.
2.4 GHz Channel This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel
Deployment
Selection Method 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 11a, 11a/n or 11ac in the 802.11 Band field.
Aware
Select this if your APs are operating in an area known to have RADAR devices. This allows
the device to downgrade its frequency to below 5 GHz in the event a 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 This shows auto and allows the AP to search for available channels automatically in the 5
Selection Method
GHz band.
Advanced Settings
Country Code Select the country code of APs that are connected to the Zyxel Device to be the same as
where the Zyxel Device is located/installed.
The available channels vary depending on the country you selected. Be sure to select the
correct/same country for both radios on an AP and all connected APs, in order to prevent
roaming failure and interference to other systems.
