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.
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
Installation / Setup

12
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.
n 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.
Installation / Setup

13
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 direc-
tion. However, connection problems can occasionally be remedied by simply adjusting the posi-
tion of the antenna. External antennas come in all shapes and sizes. Antennas also come with
different connectors. The WHR2-G54 has an ‘TNC Connector (male)’ on it. Thus, the antenna
must also have a RP-TNC connector (female).
The antenna can be removed to replace with a higher gain antenna or directional antenna simply
by unscrewing it counter-clockwise.
Please be familiar with and adhere to all FCC regulations when introducing new hardware in use
with your AirStation.

Wireless Security Setup
Encrypting your wireless data is important to
prevent other devices from being able to moni-
tor your wireless data transmissions.
There are two options available TKIP or WEP.
One or the other may be selected, or you can
choose not to enable security and allow open
movement of traffi c.
TKIP - check with your client adapter vendors to make sure that ALL of your wireless adapters sup-
port this method of WPA encryption.
WEP - while most wireless adapters support WEP, it has been shown not to be as robust as TKIP,
though it is considered adequate for home use.
Disabled - when security is disabled, clicking Continue will return you to the Home screen where
other confi gurations can be made or you can Log Out of the access point and begin using your
AirStation normally.
