Installation / Setup
About the AirStation CD
The AirStation does not require any software to
be installed on your computer for configuration.
The AirStation CD contains client drivers for
Buffalo Wireless Adapters (i.e. Notebook Adapter
and Desktop PCI Adapter) and the AirStation
documentation.
Prior to copying or installing any software, please
read the Software License Agreement “license.txt”,
located in the root folder of the CD. By installing,
copying or using the AirStation software, you are
consenting to the terms of this agreement. If you
do not agree to all of the terms of the Software License Agreement, do not download, copy or install
the AirStation software.
It is the policy of Buffalo Technology to improve
products as new technology, components, software and firmware become available.
Please consult the AirStation wireless website (http://www.buffalotech.com/wireless) to download
and install the latest firmware for your product.
Follow these simple steps to connect the AirStation to your Broadband Internet connection allowing
11
Installation / Setup
you to combine and share wired and wireless computers and printers with the high-speed internet
connection.
1. Power down the cable or DSL modem and the computer which will be used to configure the
AirStation router.
2. Plug the cable or DSL’s LAN Ethernet cable into the AirStation’s WAN port. Initially, you may
need to unplug this cable from your computer, hub or other router.
3. Plug the provided Ethernet cable into a LAN port on the AirStation and plug the other end into
your computer Ethernet adapter’s (NIC) port. If you plan to initially configure the AirStation via a
wireless connection, (not recommended), you may skip this step.
4. Power on your cable or DSL modem, wait one full minute, Power on the AirStation router, wait
another full minute and then power on the computer which will be used to configure the AirStation. If the red DIAG light on the AirStation is lit or flashing after several minutes of being powered on, please consult Buffalo Technical Support.

Antenna Installation
The WBR2-G54 has two internal antennas. One has a
vertical orientation while the other has a horizontal orientation. This setup is ideal because it allows for proper antenna
polarization with both desktop and notebook style wireless
adapter antennas.
However, it may be necessary to increase your range further
by installing an external, higher-gain antenna. External
antennas come in all shapes and sizes. Antennas also
come with different connectors. The WHR2-G54 has an ‘MC
Connector’ on it. Thus, the antenna must also have an MC
connector.
To install the antenna, slide the antenna connector door on
the back of the WBR2-G54 to the right. This will expose the
MC Connector. Attaching the antenna is simple, just insert
the antenna’s MC Connector into the WBR2-G54’s MC Connector and firmly push it in until it snaps into place. Once
snapped, the antenna’s connector will swivel with ease. It is
important not to push the antenna connector in at an angle.
To remove the antenna, pull the antenna connector out. It is
important not to pull the antenna connector out at an angle.

AOSS
AOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless
clients to an access point while setting up the most secure possible connection. Users no longer
need to worry about choosing the proper security protocols, IP addresses, or ESS-ID's. The
intelligence of AOSS determines the most optimal connection and configures itself in seconds.
■ NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and
client. You must have a Buffalo AOSS enabled wireless client device to use the AOSS features of
your AOSS Access Point/Router.
◗ Configure your WBR2-G54's internet con-
nection by referring to the instructions in
the WBR2-G54's Quick Setup Guide.
◗ Once the WBR2-G54 has been config-
ured, follow the directions to install your
wireless client device and its drivers if
necessary. Certain wireless client adapters require client software to configure
them. If your device has a Client Manager, then install it as well.
■ NOTE: If the wireless client adapter is
installed on a PC, then the AOSS client
manager will need to be installed as well. If your wireless client adapter is a standalone device that
does not require a PC, then just power up the device.
Standalone Devices: Ethernet Converters and Access Point Bridges
Client Manager Devices: CardBus, USB, and PCI Adapters.

◗ Now that the WBR2-G54 and wireless client adapter are
installed, you can use AOSS to configure them.
◗ To begin the configuration, press the AOSS button on
the back of the WBR2-G54 for 3-5 seconds. The AOSS
light will begin to flash when the AOSS mode has been
enabled. You can stop pressing the button at this point.
■ NOTE: AOSS mode will stay active for a period of
two minutes. This is the time-slot required to initiate the
wireless client adapter. The AOSS LED will stop flashing
when AOSS mode has stopped or timed out.
◗ Refer to your wireless client adapter's AOSS
supplement to initiate the wireless client adapter's AOSS
mode.
◗ It typically takes 10-15 seconds for the AOSS light to
stop flashing after the AOSS button has been pressed
on the wireless client adapter. Once configuration is
complete, the AOSS light will remain steady. Please
refer to your wireless client adapter's supplement for the
remainder of the setup.
25
AOSS
Additional AOSS Information:
◗ Only one AOSS wireless client adapter can be configured to the AOSS router at a time. Thus,
the button will need to be repressed for each additional AOSS wireless client adapter that will be
connected.
◗ It is not necessary to AOSS client devices that have already been configured via AOSS, unless
significant changes have been made to the wireless network.
◗ Do not attempt to configure two separate AOSS networks at the same time, as it may cause
undesired configurations.
◗ If an undesired client has connected via AOSS, it can be disconnected from within the WBR2-
G54's advanced configuration menus.

If there are multiple APs in close proximity using the same channel, there may be interference. In
this case, change to a non-overlapping channel.
Privacy Separator - Enable or disable communication between wireless clients. If you choose to
use this feature, every wireless client that is associated to the AirStation will not be able to communicate with any other wireless clients.
■ Note: If this function is used, wired clients can still communicate with wireless clients.
BSS (Basic Service Set) Basic Rate Set - The transmission data rates offered by the AirStation.
It is recommended to use the ‘Default’ selection to accomidate 802.11 and 802.11b rate sets. It is
NOT recommended to use the ‘All’ selection, as some devices may not understand all of the rate
sets offered by the AirStation.
Frame Bursting - This function increases 802.11b communication throughput by transferring packets more efficiently. The following conditions affect this function:
• The wireless LAN client adapter must support Frame Bursting (and it must be enabled). If
the wireless LAN client adapter does not support Frame Bursting, or Frame Bursting is not
enabled, then it will operate at non-Frame Bursting speeds.
It is recommended to leave Frame Bursting enabled as it can only help throughput, not hurt it.
DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This
parameter sets the beacon transmission interval time (1-255 seconds). Selection of a larger number may conserve energy for the client computer (when client power management is enabled), but

may delay wireless communication. The default value of 1 is recommended.
Wireless output power - Confi gure output power of the AirStation. Decrease wireless output
power to shrink the wireless communication range. The default setting of 100% is recommended
unless decreased range is desired

AirStation will not be found unless the specifi c AirStation’s SSID is entered in the client computer

Data Encryption - Disable to have
