LABEL | DESCRIPTION |
SSID Profile | The SSID (Service Set IDentifier) identifies the Service Set with which a wireless |
| station is associated. Wireless stations associating to the access point (AP) must |
| have the same SSID. Select an SSID Profile from the |
| Note: If you are configuring the NWA from a computer connected to the wireless |
| LAN and you change the NWA’s SSID or security settings, you will lose your |
| wireless connection when you press Apply to confirm. You must then |
| change the wireless settings of your computer to match the NWA’s new |
| settings. |

Channel | Select the operating frequency/channel depending on your particular region from |
| the |
|
|
Channel Width | This field displays only when you select 802.11 b/g/n in the 802.11 Wireless |
| Mode field. |
| A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a |
| 40MHz channel uses two standard channels and offers speeds of up to 300Mbps. |
| However, not all devices support 40MHz channels. |
| Select the channel bandwidth you want to use for your wireless network. |
| It is recommended that you select 20/40 (20/40 MHz). This allows the NWA to |
| adjust the channel bandwidth depending on network conditions. |
| Select 20 MHz if you want to lessen radio interference with other wireless devices |
| in your neighborhood. |

Advanced Settings
Beacon Interval | When a wirelessly network device sends a beacon, it includes with it a beacon |
| interval. This specifies the time period before the device sends the beacon again. |
| The interval tells receiving devices on the network how long they can wait in |
| lowpower mode before waking up to handle the beacon. A high value helps save |
| current consumption of the access point. |
|
|
DTIM Interval | Delivery Traffic Indication Message (DTIM) is the time period after which |
| broadcast and multicast packets are transmitted to mobile clients in the Active |
| Power Management mode. A high DTIM value can cause clients to lose |
| connectivity with the network. |
|
|
Output Power | Set the output power of the NWA in this field. If there is a high density of APs in |
| an area, decrease the output power of the NWA to reduce interference with other |
| APs. Select one of the following Full (Full Power), 50%, 25%, 12.5% or Min |
| (Minimum). See the product specifications for more information on your NWA’s |
| output power. |
|
|
Preamble Type | Select Dynamic to have the AP automatically use short preamble when wireless |
| adapters support it, otherwise the AP uses long preamble. |
| Select Long if you are unsure what preamble mode the wireless adapters support, |
| and to provide more reliable communications in busy wireless networks. |
|
|
RTS/CTS | (Request To Send) The threshold (number of bytes) for enabling RTS/CTS |
Threshold | handshake. Data with its frame size larger than this value will perform the RTS/ |
| CTS handshake. Setting this attribute to be larger than the maximum MSDU (MAC |
| service data unit) size turns off the RTS/CTS handshake. Setting this attribute to |
| its smallest value (1) turns on the RTS/CTS handshake. |
|
|
Fragmentation | The threshold (number of bytes) for the fragmentation boundary for directed |
| messages. It is the maximum data fragment size that can be sent. |
