About the Operation Modes
This device provides four operational applications with Portable Router, Bridge, Client (Adhoc) 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.
AP 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.
GW Mode
When GW mode is selected, the AP will enter the gateway mode. And the wireless connection
will be set up from a point-to-point local LAN into a point-to-multipoint WAN.

Configuration
Login
1. Start your computer. Connect an Ethernet cable between your computer and the Wireless
Portable Router.
2. Make sure your wired station is set to the same subnet as the Wireless Portable Router,
i.e. 192.168.1.254
3. Start your WEB browser. In the Address box, enter the following:
HTTP://192.168.1.254
The configuration menu is divided into four categories: Status, Wireless, TCP/IP, and
Other settings. Click on the desired setup item to expand the page in the main
navigation page. The setup pages covered in this utility are described below.
No username and password required for the fist login, however, you can set up a set of
username and password for the future security, for detailed configuration, please refer to the
Password in the later section of Configuration.

any wireless station.
You can choose one mode of the following you need.
2.4GHz (B): 802.11b supported rate only.
2.4GHz (G): 802.11g supported rate only.
2.4GHz (B+G): 802.11b supported rate and 802.11g supported rate.

SSID
b
Channel
Number
Security
The default is 2.4GHz (B+G) mode.
The SSID differentiates one WLAN from another, therefore, all access
points and all devices attempting to connect to a specific WLAN must use
the same SSID. It is case-sensitive and must not exceed 32 characters. A
device will not be permitted to join the BSS unless it can provide the unique
SSID. An SSID is also referred to as a network name because essentially it is
a name that identifies a wireless network.
Allow user to set the channel manually or automatically.
If set channel manually, just select the channel you want to specify.
If “Auto” is selected, user can set the channel range to have the Wireless
Portable Router automatically survey and choose the channel with best
situation for communication.
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.
Click the Setup button to enter the Security setup page.
Authentication: Select an Authentication from the pull-down list including
Open system or Shared Key, Open System, Open System with 802.1x,
Shared Key, WPA-RADIUS, WPA-PSK, WPA2-RADIUS and WPA2PSK.
Encryption: Select the type of encryption from the pull-down list either non
or WEP.
Use 802.1x Authentication: Select 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.
Pre-Shared Key Format: Select Passphrase or Hex (64 characters)
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.
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
efore a client associates. The advantage is that the client reduces the time

that it's disconnected to the network.
Authentication RADIUS Server: RADIUS is an authentication,
authorization and accounting client-server protocol. The client is a Network
Access Server that desires to authenticate its links. The server is a server that
has access to a user database with authentication information.
Port: Enter the RADIUS Server’s port number provided by your ISP. The
default is 1812.
IP Address: Enter the RADIUS Server’s IP Address provided by your ISP.
Password: Enter the password that the AP shares with the RADIUS Server.
Enable Accounting: Check to enable this function.
Accounting RADIUS Server: Port: Enter the RADIUS Server’s port
number provided by your ISP. The default is 1812.
IP Address: Enter the RADIUS Server’s IP Address provided by your ISP.
Password: Enter the password that the AP shares with the RADIUS Server.
Apply Changes: Click to save and apply the current settings.
Reset: Click to clear and reset the current settings.
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.

Access
y
Control
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).
Inactivity Time:
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 Mbp s. For most n etwork s the d efault settin g
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. (Note: If you want to change the Preamble type into Long
or Short, please check the setting of AP)
Broadcast SSID:
Disable: This wireless AP will not broadcast its SSID to stations. If stations want to connect
to this wireless AP, this AP’s SSID should be known in advance to make a connection.
Enable: This wireless AP will broadcast its SSID to stations.
