Getting Ready
note of the AirStation’s wired MAC address. The LAN
or Wired MAC address is the default SSID (wireless network
name) of the AirStation. You can find it on the bottom of the
You may also wish to contact your ISP to ask if other information, such as global IP address,
subnet mask address, default gateway address, DNS server address, or PPPoE parameters,
is necessary to access your internet connection. Write down any necessary information
that your ISP requires for connection.
Buffalo recommends using a wired network connection, where your computer is physically
connected to the AirStation with a CAT5 straight cable plugged into one of the four LAN ports,
to initially set up your router. This type of setup will eliminate possible setup problems with
the wireless adapter on the computer being used to configure the AirStation.
The computer used to configure the AirStation should be set to obtain an IP address automatically using a DHCP server. The WHR-G54S has a default LAN IP address of
and Subnet Mask of
Connecting your AirStation
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’s Ethernet adapter (NIC). If you plan to initially configure the
AirStation wirelessly (not recommended), you may skip this step.
4. Power on your cable or DSL modem and wait one full minute, then power on the
AirStation router and wait one full minute, and finally, 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 Technology
Technical Support.
Log in to the Configuration Tool
Launch a web browser on the computer that you’re
going to use to configure the AirStation.
Enter into the URL field. Naturally, if you
change your AirStation’s IP address, you’ll have to enter
the new address instead.
A window will open, prompting you to enter a User ID
and Password.
Enter root as the User name and leave the password
field blank.
Detecting Your Broadband Connection
Your AirStation’s SmartRouter technology will determine the type of internet
connection you have automatically, and ask you for any needed information. If
your ISP assigns IPs automatically (most cable providers do), their DHCP server
will give your router an IP address. If additional login information is required
to connect to the internet, the wizard will ask for it. Enter any required login
information if asked. Contact your DSL
provider for any missing login information.
If your DSL provider requires that PPPoE
information be entered manually, see page
This is the opening page of your
AirStation’s configuration tool. You
can always get to it from within the
configuration screens by clicking on
Home. From here, you can configure
port mapping for your internet games,
turn on UPnP for Windows (MSN)
Messenger, configure your Firewall,
setup Encryption, choose your Wireless
channel, update your AirStation’s
firmware, and reset your Internet
connection’s configuration. As you
explore the configuration tool, you can
usually get context sensitive help by clicking on the Help link at the top right of
the page.
To go to Advanced Settings (page 25), click on the Advanced tab. To get the
system information you need to set up a wireless client that doesn’t support
AOSS, click on the System Info tab. See page 17 for more on Home.
AOSS (AirStation One-Touch Secure System) is a simple system for
configuring your wireless network securely. If your router and your client
device are connected and both support AOSS, then making a secure wireless
connection is very easy.
Push the AOSS button on the top of your router and hold it in for a few
seconds. The AOSS light will begin to flash amber. You now have two minutes
to push the AOSS button on your client device and finish the connection.
If you have a standalone client device,
it will probably have a little red button
labled “AOSS” on it. Push the button!
About 15 seconds later, you’ll have a
secure network connection.
If your client device is a PC card,
CardBus, or PCI adaptor, the AOSS
button will probably be in its Client
Manager Software. Check your client
device’s user manual for instructions
on where to push or click the AOSS
client device
PC card
Client Manager
After you’ve pressed both buttons, it will take about 15 seconds for the connection to
complete. When it’s finished, the AOSS light witll glow a solid amber. You now have a
secure network connection!
AOSS Notes
Some things to keep in mind
Only one AOSS wireless client adapter can be configured with the AOSS router at a
time. The buttons will need to be re-pressed to connect each additional AOSS wireless
client adapter.
It is not necessary to AOSS client devices that have already been configured via AOSS,
unless significant changes have been made to the wireless network.
Do not attempt to configure two separate AOSS networks at the same time, as it may
cause undesired configurations.
If an undesired client has connected via AOSS, it can be disconnected from within the
WHR-G54S’s advanced configuration menus.
Router/Access Point Mode
This AirStation supports quickly changing the
product from a wireless router to a conventional
access point.
Put your Airstation into Access Point Mode
by moving the switch on the bottom of your
AirStation from AUTO to BRI. This changes
the default IP address of the AirStation from to, and DHCP,
NAT, and the WAN port are disabled.
Access Point Mode might be desirable if you’re adding wireless capability to an existing
network with a router. It is not suitable for most home configurations. If you plan to
use the AirStation as an normal wireless router, make sure that this switch is in the normal
(AUTO) position!
To set up your AirStation as a bridge or repeater, turn to page 43.
Manual Client Configuration
If your wireless client doesn’t support
AOSS, you’ll have to configure it
manually. From the Home page, click
on the System Info tab.
System Info
This page gives you all the
information you might need to
configure your non-AOSS wireless
client. Probably you’ll just need
the SSID, encryption type, and
password. Consult your wireless
client’s documentation for more
information on configuring it if
You can get here from Home by

802.11g (Basic)
If you have a mixed mode network,
with both 802.11b and 802.11g clients,
it’s recommended that you check 11g
protection to ensure that slower 11b clients
don’t hog all available bandwidth.
Choosing Auto for Wireless mode lets both
802.11b and 802.11g clients connect to the
network. If you would prefer to allow only
one or the other, you have those options as
Two different framebursting modes are
available. These can double throughput in
your network if all clients are configured
to use them. 125* High Speed Mode is an
improved version of Framebursting and is
highly recommended if your clients support
it. If a framebursting mode is enabled and
some of your clients don’t support it, it
simply won’t be used.
Reducing the Sending Output below 100%
will reduce the range of your router.
802.11g (Security)
Buffalo recommends that you choose
the strongest form of encryption that’s
supported by all your client devices.
• WEP is a lot better than nothing, and
almost every wireless device ever made
supports it.
• TKIP is slower than WEP but much more
• AES is the most secure of all, and the
quickest as well. Use it if you can.
Setting the key renewal period too short
can decrease network performance.
By default, the AirStation broadcasts its SSID. This makes it easier to have a client
connect to the AirStation. To disable broadcasting, uncheck this box.

4. Restart PC.
The WHR-G54S’s external antenna will usually give the best
performance if oriented to point straight up. If your AirStation is
resting on its side, use the antenna’s swivel and twist function to
orient it pointed upward.
In some environments it’s desirable to further increase range by
installing an external, higher-gain antenna. External antennas come
in all shapes and sizes. Antennas also come with different connectors.
The WHR-G54S has an RP-SMA connector on it. If your antenna has
a different kind of connector, you’ll need an adaptor.
To install a different antenna, unscrew the stock antenna from
the RP-SMA connector on top of the AirStation, and screw on the
connector or adaptor from your new antenna.

Configuring a WDS Bridge
Your AirStation’s WDS bridging capability allows you to extend the size of your wireless network
by adding additional AirStations, all connected wirelessly.
In this simple example, we’ll connect two AirStations in a wireless bridge. You may use these
same steps to add additional bridges for greater coverage.*
For easiest configuration, we recommend configuring all components in close proximity before
deploying them to their final positions. Wired connections make initial configuration even
The first AirStation will be the router that
receives the internet connection. On the bottom
of the AirStation, make sure that the switch
is set to “AUTO”. If desired, you may connect
the Ethernet cable from your cable or DSL
modem to its WAN port now, though this is not
necessary for configuration. Power on the first
The second AirStation will be configured as a
repeater/bridge. Make sure that its switch is
set to “BRI”. Use a RJ-45 cat5 Ethernet cable to
connect LAN ports of the two AirStations. Power
up the second AirStation.
Configuring a WDS Bridge
Connect a PC’s Ethernet port to another RJ-45 port on the main router (the first
AirStation). You will use this PC to configure the settings of the AirStations.
Here’s the whole setup, ready for initial configuration.
* Note: Each AirStation may be part of 6 different bridges. Remember that each layer
of bridges takes about half your total network speed, so avoid configuring daisy-chains
more than 4 bridges long. A star-pattern is always better, with a central router serving
multiple bridges.
Configuring a WDS Bridge
Once the AirStations are powered on, you will
want to make sure that they are in factory
default configuration. On the bottom of each,
hold down the “INIT” button for three seconds.
This will reset them to factory defaults. They
will take 30-60 seconds to reboot afterwards.
Power on your PC. Make sure that it
is configured to “obtain an IP address
automatically” from DHCP. Open a web
browser and in the address field, enter This is the default IP address
of your first AirStation.
A login window will pop up. The default
username is “root”. Leave the password field
blank and click OK.
Configuring a WDS Bridge
The Web-Based Configuration Utility for your first
AirStation will open. Click on the Advanced tab.
On the left side menu, click on Wireless Config, and then
Change the Wireless Channel from Auto to a channel.
Make a note of the channel that you’ve chosen, because all
of your wireless devices will need to be configured to use
this same channel. Change Framebursting from 125 High
Speed Mode to Framebursting or Do not use (Framebursting
is recommended if all your client devices support it). Click
Apply. Your AirStation will reboot in 30-60 seconds.
Optional: Note the SSID of this AirStation. By default,
this value will be different for each AirStation. For easy
roaming, you may want to change the SSIDs of both
AirStations to a constant value.
Configuring a WDS Bridge
On the left-side menu, click on Wireless Config, and
then Repeater.
Repeater-Bridge (WDS) must be set to Enable. If it is
not, change it to Enable in the drop down menu and
click Apply. After the AirStation reboots, the screen
will refresh. Click Edit Registered WDS Partners.
Under Add New WDS Partner Access Point, enter the
wireless MAC address of the second AirStation, the
one that you want to form a bridge with. You can
get this from the bottom of the second AirStation (see
above). Enter it with each pair of digits separated
by a colon, e.g. 000D0B10F778 would be entered
“00:0D:0B:10:F7:78”. Press New Partner when done.
The AirStation will reboot, and when the screen
refreshes, the second AirStation’s MAC address will
be listed under Bridgeable Access Points.
Configuring a WDS Bridge
Now, you need to configure the second
AirStation with the MAC address of the
first one. In your browser’s address field,
enter “”. This will take
you into the Web-Based Configuration
Utility for the second AirStation.
Once again, the username is “root” and
the password is blank.
Configuring a WDS Bridge
In the Web-Based Configuration Utility, click on the
Advanced tab, select Wireless Config, and choose
Basic. Change the wireless channel to match the one
you set for the first AirStation. Change Framebursting
from 125 High Speed Mode to Framebursting or Do not
use (whichever you chose for the first AirStation). For
easy roaming, you may change the SSID to match the
current SSID setting of the other AirStation. Click
Apply. Your AirStation will reboot in 30-60 seconds.
Now, under Wireless Config, choose Repeater.
Confirm that Repeater-Bridge (WDS) is set to Enable.
Click Edit Registered WDS Partners.
Configuring a WDS Bridge
Under Add New WDS Partner Access
Point, enter the wireless MAC address of
the first AirStation (available from the
bottom of the first AirStation), with each
pair of digits separated by a colon, e.g.
MAC:000D0B10F779 would be entered
00:0D:0B:10:F7:79. Click New Partner
when done. The AirStation will reboot,
and when the screen refreshes, the first
AirStation’s MAC address will be listed
under Bridgeable Access Points.
The two AirStations are now linked by a wireless bridge. Unplug all the network cables
and test the bridge by logging into each of the access points with a wireless client. You
should be able to connect to either of the access points from Windows Wireless Network
connection, getting an IP address assigned to your client with no error messages. You
should also be able to log into both of their Web-Based Configuration Utilities by
entering their IP addresses into a web browser ( for the main access point; for the bridged access point). If the first AirStation is connected to the
internet, you should be able to connect to the second AirStation and surf the web.
Configuring a WDS Bridge
Once you can connect to each of your access
points, you should configure WEP encryption.
Without WEP, anyone within range of
your access points can easily connect to
your network. From within the second
AirStation’s Web-Based Configuration Utility
(, click on Advanced, then
Wireless Config, then Security. Note that
you must set up WEP on the bridge (second
AirStation) first, before configuring it on the
main router (first AirStation), or you will have
to reconnect the network cables to finish
Change wireless encryption from “no encryption” to “WEP”. Note that TKIP and AES
encryption schemes will not work with WDS; you must use WEP for encryption. WEP
keys may be any of 4 different types; choose one of the following types from the dropdown “WEP Encryption Key” box:
Character Input - 13 characters (ASCII WEP128 104 bit, key should contain 13
alphanumeric characters a-z, A-Z, 0-9)
Character Input - 5 characters (ASCII WEP64 40 bit, key should contain 5 alphanumeric
characters a-z, A-Z, 0-9)
Configuring a WDS Bridge
Hexadecimal Input - 26 digits (Hex WEP128 104 bit, key should contain 26 characters
A-F, 0-9)
Hexadecimal Input - 10 digits (Hex WEP64 40 bit, key should contain 10 characters A-F,
Enter at least one encryption key in the first encryption key space. The key should
match the format of the chosen WEP encryption type. Additional keys may be entered in
boxes 2, 3, and 4.
Click Apply when finished.
After configuring the bridge (the second AirStation) for WEP, log into the first AirStation’s
Web-Based Configuration Utility ( and make exactly the same changes
to the WEP settings. All WEP configuration settings must be exactly the same, or the
AirStations will not be able to communicate.
Each wireless client that will connect to the AirStations must also be configured with the
exact same WEP encryption key type and encryption key. Consult your wireless client’s
documentation for more information on configuring its WEP settings.
Troubleshooting WDS
Most problems with setting up WDS are caused by incorrectly entering the MAC
addresses into each AirStation’s Web-Based Configuration Utility. If you’re having
problems, check the MAC address settings in both AirStations’s Web-Based Configuration
Utilities. Each Airstation should be configured to be in a bridge with the other’s wireless
MAC address.
Confirm that all bridges are set to the same wireless channel.
Check the Packet Log (Advanced/Diagnostic/Packet Info) in each AirStation’s WebBased Configuration Utility to confirm communication between them (screenshot to
right). The “WDS” entries should show packets both
sent and received. In this example, the packet log
shows packets sent but not received, so the next
troubleshooting step would be to check the other
AirStation’s settings and packet log for more clues.
If you cannot access the AirStations wirelessly,
reconnect the Ethernet cables as shown on page
67 to easily access the AirStations’s Web-Based
Configuration Utilities.
Troubleshooting WDS
Notes on WDS:
1. All wireless access points in the wireless bridge need to support WDS. At time of
publication, only Buffalo G54 and Apple Airport Extreme access points support WDS.
2. No single access point can communicate with more then six other access points in the
wireless bridge.
3. Start the wireless bridge system with only two access points and then add more, one
at a time.
4. Set up all access points in the wireless bridge in close proximity before deploying them
to their final location.
5. Only one access point in the wireless bridge should be serving DHCP and routing
services unless a routed wired network exists.
