DESCRIPTION
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.
In this field, select the SSID of the AP you want to use (click Site Survey button
for a list of available APs). Click Apply. Set the security configuration for this
operating mode in the Wireless > Security screen. Check the Status screen to
check if the settings you set show in the WLAN information.
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.
This shows the operating frequency/channel in use. This field is read-only when
you select Wireless Client as your operation mode.
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.
Choose Manual to configure the NWA's MAC address by cloning the MAC address
from a computer on your LAN. Choose Auto to use the factory default MAC
address of your NWA.
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.
Select Dynamic to have the NWA automatically use short preamble when the
wireless network your NWA is connected to supports it, otherwise the NWA uses
long preamble.
Select Long preamble if you are unsure what preamble mode the wireless device
your NWA is connected to supports, and to provide more reliable communications
in busy wireless networks.
(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.
You can use CTS to self or RTS-CTS protection mechanism to reduce conflicts
with other wireless networks or hidden wireless clients. The throughput of RTS-
CTS is much lower than CTS to self. Using this mode may decrease your wireless
performance.
