Wireless Radio Settings
Country: Select a Country/Region to conform to local regulations. Different regions have different rules
that govern which channels can be used for wireless communications.
Wireless Mode: Select from the drop-down menu to set the wireless mode for the Access Point. For
2.4GHz, the available options are 802.11b/g/n mixed, 802.11b, 802.11b/g mixed, 802.11g, and 802.11n.
For 5GHz, the available options are 802.11a/n mixed, 802.11a, and 802.11n.
Channel HT Mode: Use the drop-down menu to select the Channel HT as 20MHz, 20/40MHz or 40MHz.
A wider channel improves the performance, but some legacy devices operate only on either 20MHz or
40 MHz. This option is only available for 802.11n modes.
Extension Channel: Use the drop-down menu to set the Extension Channel as Upper or Lower channel.
An extension channel is a secondary channel used to bond with the primary channel to increase this
range to 40MHz allowing for greater bandwidth. This option is only available when Wireless Mode is
802.11n and Channel HT Mode is 20/40MHz or 40MHz.
Channel: Use the drop-down menu to select the wireless channel the radio will operate on. Optimizing
channel assignments reduces channel interference and channel utilization for the network, thereby
improving overall network performance and increasing the network's client capacity. The list of available
channels that can be assigned to radios is determined based on which country the Access Points are
deployed in.
