Bridge Mode
Refer to the illustration below. While acting as Bridges, AP1 (with Station1 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 Station1 and Station 2 are able to access the Internet if only AP1 orAP2 has the
Internetconnection.
To set the operation mode to Bridge, please go to “Wireless ??Basic Settings”,in the
“Mode” field click the down arrow ?to select AP mode. And go to “Wireless ??WDS
Settings” to enableWDS.
Note:
To act as Bridge, bothAP1and AP2 must haveWDS enabledand add each other as its
WDS Access Point.(e.g. Add AP2’s MAC address toAP1’s “WDSAPList” and vice
versa)

Client Mode (Infrastructure)
If set to Client(Infrastructure) mode, this device can work like a wireless stationwhen it’s
connected to a computer so that the computer cansendpackets from wired end to wireless
interface.
Refer to the illustrationbelow. Th is station (AP1 plusthe connected computer 1) can
associate to another Access Point (AP2), and then can have the Internet access if the other
Access Point (AP2) has the Internet connection.
To set the operation mode to Client (Infrastructure), please go to “Wireless ??Basic
Settings”, in the“Mode” field click the down arrow ?to select Client mode, and then
select “Network Type” as “Infrastructure”.

Authentication Ty pe To provide a certain level of security, the IEEE 802.11
standard has defined two types of authentication methods,
Open SystemandShared Key. With Open System
authentication,a wireless PC can join any networkand
receive any messages that are not encrypted. With Shared
Key authentication,only those PCs that possess the correct
authentication key can jointhe network. Bydefault,IEEE
802.11wirelessdevices operateinan OpenSystem network.
Wired Equivalent Privacy (WEP) dataencryption is used
when the wireless devices are configured to operate in
Shared Key authentication mode.
If the Access Point is using "Open Authentication”, then
the wireless adapter will need to beset to the same
authenticationmode.
Shared Authentication is used when both the sender and
the recipient share a secret key.
Select Autofor the network adapter to select the
Authentication mode automaticallydependingon the Access
18

19
Point Authentication mode.
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 AccessPoint, but are not within range of each other. Therefore, they
are hidden nodes for each other. When a station starts datatransmission 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
prevent data collisions. When you enable RTS Threshold on
a suspect “hidden station”, this station and its Access Pointwill use a Request to Send (RTS). The station will send an
RTS to the Access Point, info rming 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. The RTS mechanism will be activated if the data
size exceeds the value you set.. 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).
DTIM Period DTIM stands for Deliver yTraffic Indication Messa ge. A

20
DTIM is a countdown field informing clients of the next
window for listening to broadcast and multicast messages.
When the access point has buffered broadcast or multicast
message for associated clients, it sends the next DTIM with
a DTIM Period value. Access point clients hear and awaken
to receive the broadcast and multicast messages. The default
DTIM period is ‘3’.
Data Rate By default, the unit adaptively selects the highest possible
rate for transmission. Select the basic rates to be used among
the following options: Auto, 1, 2, 5.5, or 11 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
performance 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.
Tx Power Level Select the power level to transmit packets.
IAPP To enable IAPP means that Access Points will communicate
across the backbone network, so that mobile stations can
roam between them.
Apply Change Press to save the new settings on the screen.
Reset Press to discard the data you have entered since last time
you press Apply Change.

Security
Here you can configure the securityofyourwireless network. Selecting different method
will enable youtohavedifferentlevel of security. Please no te that byusing any
encryption, bywhich data packet is encrypted before transmission toprevent datapackets
from being eavesdroppedby unrelated people, there may be a significant degradationof
the datathroughput on the wireless link.
Encryption: None ( Encryptionis set to Noneby default.)
