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 rear of the AirStation. 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

11

Installation / Setup

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.

Open the Setup Screen

• Connect the WYR-G54 according to the wiring instructions in Section 2.

• The WYR-G54 has a default LAN IP address of 192.168.11.1 and Subnet Mask of 255.255.255.0.

■ Note: The computer used to configure the AirStation should be set to obtain an IP address

automatically using a DHCP server. The Quick Setup Guide enclosed with the product contains
detailed instructions on how to configure your computer for initial configuration.

On the computer used to configure the AirStation, launch a Web Browser 4.5 or later.

- Enter 192.168.11.1 into the URL field.

- A window will open prompting you to enter a User ID and Password.

12

Antenna

The WYR-G54 has one internal omnidirectional antenna. The
transmission of wireless signals is isotropic, meaning that the
waves are emitted much like the sun distributes light in every
direction. However, connection problems can occasionally
be remedied by simply adjusting the position of the 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 WYR-G54 to the right. This will expose the
MC Connector. Attaching the antenna is simple, just insert
the antenna’s MC Connector into the WYR-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.
