connection.
Introduction

11
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 an-
other 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.
Installation / Setup

12
Introduction
Configuring the AirStation using a standard web browser requires basic wireless configuration
knowledge. Setup includes manual wireless configuration and basic administrative management.
Setup Preparation
Make note of the AirStation’s wired MAC address (found on the underside of the WZR-RS-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 configure the AirStation.
A Web browser version 4.5 or later can be used to configure the AirStation.
Advanced settings for security, filtering and other features will be explained in later sections.
Installation / Setup

13
The WZR-RS-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 WZR-RS-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 WZR-RS-G54 to the right. This will expose
the MC Connector. Attaching the antenna is simple, just in-
sert the antenna’s MC Connector into the WZR-RS-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.
