HARDWARE CONNECTION
Note: Before you starting hardware connection, you are advised to find an appropriate
location to place the Access Point. Usually, the best place for the Access Point is at the
center of your wireless network, with line of straight to all your wireless stations. Also,
remember to adjust the antenna; usually the higher the antenna is placed, the better will
the performance be.
Connection of using the included Power adapter:
1. Connect to your local area network: connect a Ethernet cable to one of the
Ethernet port (LAN1 or LAN2) of this Wireless Access Point, and the other end to a
hub, switch, router, or another wireless access point.
2. Power on the device: Connect the included AC power adapter to the Wireless Access
Point’s power port and the other end to a wall outlet.
Connection of using PoE:
The hardware connection is basically the same as using a power adapter to supply power
to your wireless access point, except for a different power origin it gains. With PoE, your
7
wireless access point gains power from a PSE device through simply an Ethernet UTP
cable!
Check the LEDs:
The Power and LAN # LEDs should be ON. LAN# LED will even blink if there is traffic.
The Link/Act LED will be on in static when wireless interface is turned on.
If the Status LED glows after self-test , it means this Wireless Access Point fails on self
test. Please ask your dealer for technical support.
3. Configure your PC: Make sure your local PC(s) has wireless network adapter
installed.

ABOUT THE OPERATION MODES
This device provides four operational applications with Access Point, Bridge, Client
(Ad-hoc) and Client (Infrastructure) modes, which are mutually exclusive.
This device is shipped with configuration that is functional right out of the box. If you
want to change the settings in order to perform more advanced configuration or even
change the mode of operation, you can use the web-based utility provided by the
manufacturer as described in the following sections.
Access Point Mode
When acting as an access point, this device connects all the stations (PC/notebook with
wireless network adapter) to a wired network. All stations can have the Internet access if
only the Access Point has the Internet connection.
WDS Repeater Mode
While acting as Bridges, AP1 (with Station 1 being associated to) and AP2 (with Station 2
being associated) can communicate with each other through wireless interface (with
WDS). Thus Station 1 can communicate with Station 2 and both Station 1 and Station 2
are able to access the Internet if only AP1 or AP2 has the Internet connection.
9
Client Mode (Infrastructure)
If set to Client (Infrastructure) mode, this device can work like a wireless station when it’s
connected to a computer so that the computer can send packets from wired end to wireless
interface.
Client Mode (Ad-hoc)
If set to the Client (Ad-hoc) mode, this device can work like a wireless station when it is
connected to a computer so that the computer can send packets from wired end to wireless
interface. You can share files and printers between wireless stations (PC and laptop with
wireless network adapter installed).
WDS Bridge Mode
The WDS (Wireless Distributed System) function lets this access point act as a wireless
LAN access point and repeater at the same time. Users can use this feature to build up a
large wireless network in a large space like airports, hotels and schools …etc. This feature
is also useful when users want to bridge networks between buildings where it is
impossible to deploy network cable connections between these buildings.

essentially it is a name that identifies a wireless network.
Channel Number The number of channels supported depends on the region of
this Access Point. All stations communicating with the Access
Point must use the same channel.
Encryption WEP Encryption (Wired Equivalent Privacy) is set to
Disabled by default. When WEP is enabled, data packet is
encrypted before being transmitted. The WEP prevents data
packets from being eavesdropped by unrelated people. By
using WEP data encryption, there may be a significant
degradation of the data throughput on the wireless link.

15
Authentication Type To provide a certain level of security, the IEEE 802.11
standard has defined two types of authentication methods,
Open System and Shared Key. With Open System
authentication, a wireless PC can join any network and
receive any messages that are not encrypted. With Shared
Key authentication, only those PCs that possess the correct
authentication key can join the network. By default, IEEE
802.11 wireless devices operate in an Open System network.
Wired Equivalent Privacy (WEP) data encryption is used
when the wireless devices are configured to operate in
Shared Key authentication mode.
If the Access Point is using Open System, then the wireless
adapter will need to be set to the same authentication mode.
Shared Key is used when both the sender and the recipient
share a secret key.

Fragment Threshold Fragmentation mechanism is used for improving the
efficiency when high traffic flows along in the wireless
network. If your 802.11g Wireless LAN PC Card often
transmit large files in wireless network, you can enter new
Fragment Threshold value to split the packet. The value
can be set from 256 to 2346. The default value is 2346.
RTS Threshold RTS Threshold is a mechanism implemented to prevent the
“Hidden Node” problem. “Hidden Node” is a situation in
which two stations are within range of the same Access
Point, but are not within range of each other. Therefore, they
are hidden nodes for each other. When a station starts data
transmission with the Access Point, it might not notice that
the other station is already using the wireless medium. When
these two stations send data at the same time, they might
collide when arriving simultaneously at the Access Point.
The collision will most certainly result in a loss of messages
for both stations.
Thus, the RTS Threshold mechanism provides a solution to
p
revent data collisions. When you enable RTS Threshold on
a suspect “hidden station”, this station and its Access Point
will use a Request to Send (RTS). The station will send an
RTS to the Access Point, informing that it is going to
transmit the data. Upon receipt, the Access Point will
respond with a CTS message to all station within its range to
notify all other stations to defer transmission. It will also
confirm the requestor station that the Access Point has
reserved it for the time-frame of the requested transmission.
If the “Hidden Node” problem is an issue, please specify the
packet size. UThe RTS mechanism will be activated if the data
size exceeds the value you set.U. The default value is 2347.
Warning: Enabling RTS Threshold will cause redundant
network overhead that could negatively affect the
throughput performance instead of providing a remedy.
This value should remain at its default setting of 2347. Should you
encounter inconsistent data flow, only minor modifications of this
value are recommended.
Beacon Interval Beacon Interval is the amount of time between beacon
transmissions. Before a station enters power save mode, the
station needs the beacon interval to know when to wake up
to receive the beacon (and learn whether there are buffered
frames at the access point).
Data Rate B

rate for transmission. Select the basic rates to be used among
the following options: Auto, 1, 2, 5.5, 11or 54 Mbps. For
most networks the default setting is Auto which is the best
choice. When Auto is enabled the transmission rate will
select the optimal rate. If obstacles or interference are
present, the system will automatically fall back to a lower
rate.
Preamble Type A preamble is a signal used in wireless environment to
synchronize the transmitting timing including
Synchronization and Start frame delimiter. In a "noisy"
network environment, the Preamble Type should be set to
Long Preamble. The Short Preamble is intended for
applications where minimum overhead and maximum
p
erformance is desired. If in a "noisy" network environment,
the performance will be decreased.
Broadcast SSID Select enabled to allow all the wireless stations to detect the
SSID of this Access Point.
IAPP IAPP (Inter Access Point Protocol) is designed for the
enforcement of unique association throughout a ESS
(Extended Service Set) and a secure exchange of station’s
security context between current access point (AP) and new
AP during handoff period.
802.11g Protection The 802.11g standard includes a protection mechanism to ensure
mixed 802.11b and 802.11g operations. If there is no such kind of
mechanism exists, the two kinds of standards may mutually
interfere and decrease network’s performance.
Tx Power Level Select the Transmission rate level ranging from Highest, High,
Middle, Low and Lowest.

Security
Here you can configure the security of your wireless network. Selecting different method
will enable you to have different level of security. Please note that by using any
encryption, by which data packet is encrypted before transmission to prevent data packets
from being eavesdropped by unrelated people, there may be a significant degradation of
the data throughput on the wireless link.
Encryption: None ( Encryption is set to None by default. )
If Use 802.1x Authentication is selected, the RADIUS Server will proceed to check the
802.1x Authentication.
Encryption: WEP
If WEP is selected, users will have to Set WEP keys either manually, or select to Use
802.1x Authentication to make the RADIUS server to issue the WEP key dynamically.
19
Set WEP key Click the Set WEP Keys will prompt you a
window to set 64bit or 128bit Encryption.
Select HEX if you are using hexadecimal
numbers (0-9, or A-F). Select ASCII if you are
using ASCII characters (case-sensitive).
Ten hexadecimal digits or five ASCII
characters are needed if 64-bit WEP is used;
26 hexadecimal digits or 13 ASCII characters
are needed if 128-bit WEP is used.
Encryption: WPA (TKIP)
WPA (TKIP): If WPA is selected, users will have to select the Authentication modes
between Enterprise (RADIUS) and Personal (Pre-shared Key).
Pre-shared Key Pre-Shared-Key serves as a password. Users may key in a
8 to 63 characters string to set the password or leave it
blank, in which the 802.1x Authentication will be activated.
Make sure the same password is used on client's end.
There are two formats for choice to set the Pre-shared key,
i.e. Passphrase and Hex. If Hex is selected, users will have
to enter a 64 characters string. For easier configuration, the
Passphrase (at least 8 characters) format is recommended.
20
Group Key Life Time Enter the number of seconds that will elapse before the
group key change automatically. The default is 86400
seconds.
Enable Pre-Authentication The two most important features beyond WPA to become
standardized through 802.11i/WPA2 are: pre-
authentication, which enables secure fast roaming without
noticeable signal latency.
Preauthentication provides a way to establish a PMK
security association
b
efore a client associates. The
advantage is that the client reduces the time that it's
disconnected to the network.
Authentication RADIUS
Server Port: Enter the RADIUS Server’s port number provided by
