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.
In this field, select the SSID profile of the AP you want to use. Click
Apply
.
The SSID used in the selected SSID profile automatically changes to be the one you select
in the
Site Survey
screen.
Set the security configuration for this operating mode in the
Wireless LAN > Security
screen. Check the
Dashboard
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.
Channel
This shows the operating frequency/channel in use. This field is read-only when you select
Client
as your operation mode.
Channel Width
This field is not available in the NWA1123-NI.
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
20/40MHz
. This allows the NWA to adjust the channel
bandwidth depending on network conditions.
Select
20MHz
if you want to lessen radio interference with other wireless devices in your
neighborhood or the AP do not support channel bonding.
Advanced Settings
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%
or
12.5%
. See the product specifications for
more information on your NWA’s output power.
Preamble Type
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.
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.
Extension
channel
protection mode
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.
A-MPDU
Aggregation
This field is not available in the NWA1100-NH and NWA1123-NI.
Select to enable A-MPDU aggregation.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their
802.11n headers and wraps them in a 802.11n MAC header. This method is useful for
increasing bandwidth throughput in environments that are prone to high error rates.
