Introduction

11
Follow these simple steps to connect the AirStation to your Broadband Internet connection allowing
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 modem’s LAN Ethernet
cable into the AirStation’s WAN port. 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 and 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 Sup-
port.
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 LAN MAC address (found on the underside of the WZR-HP-G54). It
is also recommended that you record any other broadband ISP information, such as global IP ad-
dress, subnet mask address, default gateway address, DNS server address and PPPoE param-
eters.
Setup Overview
Buffalo recommends using a wired connection, meaning your computer is physically connected
to the AirStation with a CAT5 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 be-
ing used to configure the AirStation.
Installation / Setup

13
The WZR-HP-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. Available ex-
ternal antennas are described as below. Antennas also come
with different connectors. The WZR-HP-G54 has an unique
‘MC Connector’ on it. Thus, the antenna must also have an
MC connector.
The following four antennas are allowed to connect to WZR-
HP-G54.
WLE-DA: Patch Antenna
WLE-NDR: Sleeve Antenna
WLE-HG-NDR Sleeve Antenna
WLE-MYG Yagi Antenna
Antenna Installation

14
Antenna Installation
To install the antenna, slide the antenna connector door on
the back of the WZR-HP-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-HP-G54’s MC
Connector and firmly push it in until it snaps into place. Once
clicked into place, the antenna’s connector should swivel
easily. 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.

Open the Setup Screen
The computer used to confi gure the Airstation should be set to ‘obtain an IP address automatically
using a DHCP server’. Connect it to one
of the four ports on the WZR-HP-G54
with an ethernet cable. On the computer,
launch a Web Browser of version 4.5 or
later. Enter 192.168.11.1 into the URL
fi eld. A window will open prompting you
to enter a User ID and Password. Enter
“root” as the User ID and leave the pass-
word fi eld blank. Click OK to log in to the
Airstation.
■ NOTE: The WZR-HP-G54 has a default
IP address of 192.168.11.1 and a Subnet
Mask of 255.255.255.0.
