Introduction

Begin by nding a good place to set up your router/access point. Some things to
consider:
• You’ll need to be able to plug your internet connection into it, so it should go within
reach of the LAN cable from your DSL or Cable modem. You’ll also want a power outlet
nearby.
• Keep the access point as central in your work area as possible. Signal strength and
speed fall off with distance.
• Higher is often better. For instance, set it up on the top shelf of a bookcase rather than
the bottom one, if possible.
Basic Setup
Screw the antenna into the top of your AirStation. For best
performance, align the antenna to point straight up.

7
Make 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
AirStation.
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 congure the AirStation.
The computer used to congure the AirStation should be set to obtain an IP address automati-
cally using a DHCP server. The WHR-G54S has a default LAN IP address of 192.168.11.1
and Subnet Mask of 255.255.255.0.
Getting Ready

8
1. Power down the Cable or DSL modem and the computer which will be used to
congure 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 congure 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 nally, power on the computer which
will be used to congure the AirStation. If the red DIAG light on the AirStation is lit or
ashing after several minutes of being powered on, please consult Buffalo Technology
Technical Support.
Connecting your AirStation

9
Launch a web browser on the computer that you’re
going to use to congure the AirStation.
Enter 192.168.11.1 into the URL eld. 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
eld blank.
Log in to the Conguration Tool

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
Detecting Your Broadband Connection
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
