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. 
Select Auto for the network adapter to select the Authentication 
mode automatically depending on the Access 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 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 
prevent 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. 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.  
						

							23 
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 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, 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 
performance is desired. If in a noisy network environment, the 
performance will be decreased. 
Broadcast SSID   Select enabledto 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 operation. If there is no such kind of mechanism exists, 
the two kinds of standards may mutually interfere and decrease network’s 
performance.

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. 
 
  
						

							25 
 
 
Set WEP key 
ƒ Click the Set WEP Keys will prompt you a window to set 64bitor 
128bit Encryption.   
ƒ Select HEX if you are using hexadecimal numbers (0-9, or A-F). 
Select ASCII if you are using ASCII characters (case-sensitive).
ƒ 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 clients end. 
There are two formats for choice to set the Pre-shared key, i.e. 
Passphrase and Hex. If Hexis selected, users will have to enter a 64 
characters string. For easier configuration, the Passphrase (at least 8 
characters) format is recommended. 
Group Key Life Time Enter the number of seconds that will elapse before the group key

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 
before a client associates. The advantage is that the client reduces the 
time that its disconnected to the network.

Server.
