Installation / Setup
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 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 confi gure the AirStation.
A Web browser version 4.5 or later can be used to confi gure the AirStation.
Advanced settings for security, fi ltering and other features will be explained in later sections.
12
Antenna Installation
The WZR-RS-G54 has two internal antennas. One has a
vertical orientation while the other has a horizontal orientation. 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 insert the antenna’s MC Connector into the WZR-RS-G54’s MC
Connector and fi rmly 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.

AOSS
AOSS (AirStation One-Touch Secure System) is a simple, one-touch setup for connecting wireless
clients to an access point while setting up the most secure possible connection. Users no longer
need to worry about choosing the proper security protocols, IP addresses, or SSID's. The
intelligence of AOSS determines the most optimal connection and confi gures itself in seconds.
■ NOTE: AOSS automatically creates a secure connection between your AOSS Access Point and
client. You must have an AOSS enabled wireless client device to use the AOSS features of your
AOSS Access Point/Router. Intel Centrino supports AOSS by installing Buffalo's Client Manager
software.
◗ Confi gure your WZR-RS-G54’ internet
connection by referring to the instructions
in the WZR-RS-G54’ Quick Setup Guide.
◗ Once the WZR-RS-G54 has been confi g-
ured, follow the directions to install your
wireless client device and its drivers if
necessary. Certain wireless client adapters require client software to confi gure
them. If your device has a Client Manager, then install it as well.
■ NOTE: If the wireless client adapter is
installed on a PC, then the AOSS client manager will need to be installed as well. If your wireless
client adapter is a standalone device that does not require a PC, then just power up the device.
Standalone Devices: Ethernet Converters and Access Point Bridges
Client Manager Devices: CardBus, USB, and PCI Adapters.

◗ Now that the WZR-RS-G54 and wireless client adapter
are installed, you can use AOSS to confi gure them.
◗ To begin the confi guration, press the AOSS button on
the side of the WZR-RS-G54 for 3-5 seconds. The orange
AOSS light will begin to fl ash rapidly when the AOSS mode
has been enabled. You can stop pressing the button at this
point.
■ NOTE: AOSS mode will stay active for a period of two
minutes. This is the time-slot required to initiate AOSS on
the wireless client adapter.
◗ Refer to your wireless client adapter's AOSS supplement
to initiate the wireless client adapter's AOSS mode.
◗ Once the client adapter has fi nished communicating
with the AOSS router, the orange light will stop fl ashing
and become solid. This indicates that the AOSS process
has completed and the devices are now using AOSS. It
typically takes 15-60 seconds for the entire AOSS process
to complete. Please refer to your wireless client adapter's
supplement for the remainder of the setup.
24
AOSS
Additional AOSS Information:
◗ Only one AOSS wireless client adapter can be confi gured to the AOSS router at a time. Thus,
the button will need to be repressed for each additional AOSS wireless client adapter that will be
connected.
◗ It is not necessary to AOSS client devices that have already been confi gured via AOSS, unless
signifi cant changes have been made to the wireless network.
◗ Do not attempt to confi gure two separate AOSS networks at the same time, as it may cause
undesired confi gurations.
◗ If an undesired client has connected via AOSS, it can be disconnected from within the WZR-RS-
G54’ advanced confi guration menus.

If there are multiple APs in close proximity using the same channel, there may be interference. In this
case, change to a non-overlapping channel.
Privacy Separator - Enable or disable communication between wireless clients. If you choose to use this
feature, every wireless client that is associated to the AirStation will not be able to communicate with any
other wireless clients.
■ Note: If this function is used, wired clients can still communicate with wireless clients.
BSS (Basic Service Set) Basic Rate Set - The transmission data rates offered by the AirStation. It is
recommended to use the ‘Default’ selection to accomidate 802.11 and 802.11b rate sets. It is NOT recommended to use the ‘All’ selection, as some devices may not understand all of the rate sets offered by the
AirStation.
Frame Bursting - This function increases 802.11g communication throughput by transferring packets more
effi ciently. The following conditions affect this function:
• The wireless LAN client adapter must support Frame Bursting (and it must be enabled). If the wireless
LAN client adapter does not support Frame Bursting, or Frame Bursting is not enabled, then it will
operate at non-Frame Bursting speeds.
125 High Speed Mode - This function further increases 802.11g communication. Rate sets up to 125
Mbps are offered to clients.The following conditions affect this function:
• The wireless LAN client adapter must support 125 High Speed Mode (and it must be enabled). If the
wireless LAN client adapter does not support 125 High Speed Mode, or it is not enabled, then it will
operate at regular 802.11g speeds.
It is recommended to leave 125 High Speed Mode enabled as it can only help throughput, not hurt it.
27
Advanced Settings
802.11g Protection - This enables protection mechanisms for when 802.11b clients join the network. It enables CTS (Clear-to-Send)
DTIM Period - An access point transmits beacon signals to nearby clients at a preset interval. This
parameter sets the beacon transmission interval time (1-255 seconds). Se lec tion of a larger number may conserve energy for the client computer (when client power management is enabled), but
may delay wireless communication. The default value of 1 is recommended.
Wireless Output Power - Confi gure output power of the AirStation. Decrease wireless output
power to shrink the wireless communication range. The default setting of 100% is recommended
unless decreased range is desired

Broadcast SSID - Enable or Dis-
able the SSID (SSID) from being
broadcasted. If denied, the AirStation
will not be found unless the specifi c
AirStation’s SSID is entered in the
client computer manually.
Data Encryption - Disable to have no
encryption of the wireless data. This
will make accessing the AirStation
and the network very easy. It is im-
28
Advanced Settings
portant to note, that without encryption it is easy for strangers to connect to your network, especially
if the AirStation is broadcasting its SSID.
Select the type of data encryption:
• Disabled - Disable data encryption.
- WEP - Uses WEP encryption. Encryption key should be entered.
- TKIP - Uses TKIP (Temporal Key Integrity Protocol) for data encryption.
The encryption key is renewed every “Re-key interval” when “TKIP” is selected.
WEP - When the WEP (Wired Equivalent Protection) encryption standard is implemented into a
wireless network, a WEP key is used between the client and access point to successfully encrypt,
transmit and decrypt data. For this reason, the same WEP key must be used for communication
between the client and the AirStation.
An access point and client may both carry multiple WEP keys. It is necessary for not only the WEP
keys to match, but also the WEP key’s order. If a wireless client cannot support multiple WEP keys,
the AirStations must be confi gured to transmit key number 1 for a connection to take place.
Examples of WEP key:
64-bit ASCII: 5 digits of alphanumeric characters, “ab34Y”
128-bit ASCII: 13 digits of alphanumeric characters, “123456abcdef7”
■ Note: ASCII WEP keys are case sensitive.
64-bit HEX: 10 digits, using characters 0-9 and a-f, “00234ABCDE”
29
Advanced Settings
128-bit HEX: 26 digits, using characters 0-9 and a-f, “20123456789abcdeabcdeabcde”
TKIP - TKIP (Temporal Key Integrity Protocol) is a WEP expanded encryption technique. TKIP has
greatly improved WEP’s weaknesses by rotating secret keys between every packet. TKIP uses
WPA-PSK (pre-Shared Key).
Characteristics:
- The Initialization Vector is expanded from 24-bits to 48-bits.
- The Initialization Vector is randomized.
- Uses a different RC4 key for every packet.
AES - AES further improves TKIP by using AES (Advanced Encryption Standard) encryption
method. Due to its hardware co-processor, AES uses the toughest encryption without sacrifi cing
throughput like WEP and TKIP.
TKIP & AES require an 8 to 63 character passphrase in ASCII or 64 digits hexadecimal key.
Example 1: [ airstation -WPA-PSK ]
Example 2: [0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef]
WPA Group Rekey Interval - When TKIP is selected, the encryption key is renewed at this interval. This interval is in seconds; the range of acceptable values is 0-3600.
If 0 is entered, the key is never renewed.
■ Note: The lower the rekey interval, the more often a rekey occurs. Setting a low rekey interval
may affect performance negatively.
