In the Radio Setting Per Interface area, select the radio interface to which the 
configuration parameters will be applied. 

In the Basic Settings area, configure these parameters for the selected radio 
interface:

Local regulations may prohibit the use of certain radio modes. Not all modes are 
available in all countries.

•

Radio—Turns on or off the radio interface. By default, the radio is off.

•

MAC Address—Shows the Media Access Control (MAC) address for the 
interface. The MAC address is assigned by the manufacturer and cannot be 
changed.

•

Mode—Choose the IEEE 802.11 standard and frequency that the radio uses. 
The available modes are:

-

802.11a—Only 802.11a clients can connect to the WAP device.

-

802.11b/g—802.11b and 802.11g clients can connect to the WAP 
device.

-

802.11a/n—802.11a clients and 802.11n clients operating in the 5-GHz 
frequency can connect to the WAP device.

-

802.11b/g/n (default)—802.11b, 802.11g, and 802.11n clients operating 
in the 2.4-GHz frequency can connect to the WAP device.

-

5 GHz 802.11n—Only 802.11n clients operating in the 5-GHz frequency 
can connect to the WAP device.

-

2.4 GHz 802.11n—Only 802.11n clients operating in the 2.4-GHz 
frequency can connect to the WAP device.

•

Channel Bandwidth—The 802.11n specification allows a coexisting 20/40 
MHz channel in addition to the legacy 20 MHz channel available with other 
modes. The 20/40 MHz channel enables higher data rates but leaves fewer 
channels available for use by other 2.4 GHz and 5 GHz devices.

By default, when the radio mode includes 802.11n, the channel bandwidth is 
set to 20 MHz for 2.4 GHz and 20/40 MHz for 5 GHz.

•

Primary Channel (802.11n modes with 20/40 MHz bandwidth only)—A 40 
MHz channel can be considered to consist of two 20-MHz channels that are 
contiguous in the frequency domain. These two 20-MHz channels are often
