DescriptionSetting
From the menu, select the value that protects radio transmissions from interference.
An Auto guard interval (which is the default) improves performance, but some legacy
devices can operate only with a long –800ns guard interval.
The guard interval and channel width determine the available MCS index and data
transmit rates.
Guard Interval
From the menu, select the transmission power of the radio. You can select
100%(Max), 50%, 25%, 12.5%, or 4%(Min). The default is 100%(Max).
Note: If two or more access points are operating in the same area and on the same
channel, interference can occur. In such a situation, you might want to decrease the
output power for the access point. Make sure that you comply with the regulatory
requirements for total radio frequency (RF) output power in your country.
Output Power
From the menu, select the WiFi channel for the radio. The available WiFi channels
and frequencies depend on the country and the radio. (The channels in the 5 GHz
band are divided between the low band and high band radios.) The default is Auto,
which enables the radio to automatically select the most suitable channel.
Note: You do not need to change the WiFi channel unless you experience
interference (which is indicated by lost connections).
Note: If you use multiple access points, reduce interference by selecting different
channels for adjacent access points. We recommend a channel spacing of four
channels between adjacent access points (for example, use Channels 1 and 5, or 6
and 10).

The pop-up window closes and your settings are saved. The radio or radios restart
and WiFi clients might need to reconnect.
Turn a radio on or off
By default, the 2.4 GHz radio and both 5 GHz radios broadcast. Turning off a radio
disables WiFi access for the associated band, which affects all VAPs (or SSIDs) in that
band. Turning off a radio can be helpful during configuration, network tuning, or
troubleshooting.
