DESCRIPTION
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.
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.
Select the check box to activate an SSID profile.
Select the check box to enable the bridge connection. Otherwise, clear the
check box to disable it. The first profile is always active.
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.
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.
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.
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 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.
(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.
