LABEL | DESCRIPTION |

|
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. |
|
|
Select SSID Profile | An SSID profile is the set of parameters relating to one of the NWA’s BSSs. |
| The SSID (Service Set IDentifier) identifies the Service Set with which a |
| wireless station is associated. Wireless stations associating with the access |
| point (AP) must have the same SSID. |
| 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. |
|
|
Index | Select the check box to activate an SSID profile. |
|
|
Active | Select the check box to enable the bridge connection. Otherwise, clear the |
| check box to disable it. The first profile is always active. |
|
|
Profile | Select the profile(s) of the SSIDs you want to use in your wireless network. |
| You can have up to four BSSs running on the NWA simultaneously. |
| Configure SSID profiles in the SSID screen. |

|
Beacon Interval | When a wirelessly networked 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 Threshold | (Request To Send) The threshold (number of bytes) for enabling RTS/CTS |
| 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. |
