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 AirSta-
tion. If the red DIAG light on the AirStation is lit or flashing after several minutes of being pow-
ered on, please consult Buffalo Technical Support.
Installation / Setup

13
The WBR2-G54 has two internal antennas. One has a
vertical orientation while the other has a horizontal orienta-
tion. 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 Con-
nector 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.

Introduction
Confi guring the AirStation using a standard web browser requires basic wireless confi guration
knowledge. Setup includes manual wireless confi guration and basic administrative management.
Setup Preparation
Make note of the AirStation’s wired MAC
address (found on the back of the WBR2-
G54). It is also recommended you record
any other broadband ISP information
such as global IP address, subnet mask
address, default gateway address, DNS
server address and PPPoE parameters.
Setup Overview
Buffalo recommends using a wired
connection, meaning your computer is
physically connected to the AirStation with
a CAT5 straight cable plugged into one
of the four LAN ports This type of setup
will eliminate possible setup problems due to any issues with the wireless adapter on the computer
being used to confi gure the AirStation.
