2.4 GHz Channel This field is available only when you set 2.4 GHz Channel Selection Method to auto.
Deployment
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
ZyWALL/USG uses channels 1, 4, 7, 11 in this configuration; otherwise, the ZyWALL/
USG 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.
5 GHz Settings
Enable 5 GHz DFS Select this if your APs are operating in an area known to have RADAR devices. This
Aware 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 Select auto to have the AP search for available channels automatically in the 5 GHz
Selection Method band.
Select manual and specify the channels the AP uses in the 5 GHz band.
