Parameter Description
Operation Mode This Access Point can act as AP, AP Bridge and AP Repeater. There are
four kinds of operation mode for the Access Point.
•AP Mode – Act as a pure AP which enables data transmission
between wireless and wired stations in the same segment.
•AP Bridge – If you are trying to make a wireless connection
between two or more wired networks, select following setting
modes. Note that once the product sets as AP Bridge, it can only
connect to AP Bridge but not all wireless devices.
-Point-to-Point: This mode connects two wired LAN segments by
using two Access Points. Both Access Points have to set as
Point-to-Point mode and designate the MAC Address each
other.
-Point-to-Multipoint: This mode connects any AP Bridge in the
same channel, allowing you to construct a wireless network with
up to six physical LAN segments.
•AP Repeater – This mode allows the product to act as AP and AP
Bridge simultaneously.
-WDS Mode: This product supports Wireless Distribution System
(WDS) which enables you to extend the wireless network
without any wired backbone, large areas are able to be covered

and wiring is not necessity. There are some tips for setting
WDS mode described as follows.
(1)Only AP sets as WDS or AP Bridge can work together.
(2)The WDS mode may not work with some wireless products
due to possible incompatibility with other vendor’s WDS
function.
(3)You have to designate the MAC Address (supports up to six
WDS APs) of WDS AP or AP Bridge for wireless
connections.
(4)The channel of the APs has to be set as the same.
Alias Name The alias name of this access point.
ESSID The ESSID (up to 31 printable ASCII characters) is the unique name
identified in a WLAN. The ID prevents the unintentional merging of two
co-located WLANs. Please make sure that the ESSID of all stations in
the same WLAN network are the same. The default ESSID is “default”.
Channel Number Select the appropriate channel from the list provided to correspond with
your network settings. Channels differ from country to country.
Channel 1-11 (North America)
Channel 1-14 (Japan)
Channel 1-13 (Europe)
There are 14 channels available.
Associated Clients Click “Show Active Clients” button, then a “Active Wireless Client Table”
will pop up. You can see the status of all active wireless stations that are
connecting to the access point.
Click Apply button at the bottom of the screen to save the above configurations. You can now configure
other advance sections or start using the Access Point.
Active Wireless Client Table
“Active Wireless Client Table” records the status of all active wireless stations that
are connecting to the access point. You can lookup the MAC Address, Number of

Transmitted Packets, Number of Received Packets and Encryption Status of each
active wireless client in this table.
Parameter Description
MAC Address MAC address of this active wireless station.
Tx Packet The number of transmitted packets that are sent out from this active
wireless station.
Rx Packet The number of received packets that are received by this active wireless
station.

3.2.3 Advanced Setting
You can set advanced parameters of this access point. The parameters include
Authentication Type, Fragment Threshold, RTS Threshold, Beacon Interval, Tx
Operation Rate, Tx Basic Rate, Preamble Type, Broadcast ESSID. You should not
change these parameters unless you know what effect the changes will have on this
access point.
Parameter Description
Authentication Type There are two authentication types: “Open System” and “Shared Key”.
When you select “Open System”, wireless stations can associate with
this access point without WEP encryption. When you select “Shared
Key”, you should also setup WEP key in the “Encryption” page and
wireless stations should use WEP encryption in the authentication phase

Wireless LAN Access Point Configuration
18
to associate with this access point. If you select “Both”, the wireless client
can associate with this access point by using any one of these two
authentication types.
Fragment Threshold “Fragment Threshold” specifies the maximum size of packet during the
fragmentation of data to be transmitted. If you set this value too low, it will
result in bad performace.
RTS Threshold When the packet size is smaller the RTS threshold, the access point will
not use the RTS/CTS mechanism to send this packet.
Beacon Interval The interval of time that this access point broadcast a beacon. Beacon is
used to synchronize the wireless network.
Data Rate The “Data Rate” is the rate this access point uses to transmit data
packets. The access point will use the highest possible selected
transmission rate to transmit the data packets.
Preamble Type Preamble type defines the length of CRC block in the frames during the
wireless communication. “Short Preamble” is suitable for high traffic
wireless network. “Long Preamble” can provide more reliable
communication.
Broadcast ESSID If you enable “Broadcast ESSID”, every wireless station located within
the coverage of this access point can discover this access point easily. If
you are building a public wireless network, enabling this feature is
recommended. Disabling “Broadcast ESSID” can provide better security.
Click Apply button at the bottom of the screen to save the above configurations. You can now configure
other advance sections or start using the Access Point.
3.2.4 Encryption
WEP is an authentication algorithm, which protects authorized Wireless LAN users
against eavesdropping. The Authentication type and WEP key of wireless stations
must be the same with the Access Point. This Access Point supports 64/128-bit WEP
