System Requirements
• A high-speed (Broadband) Internet connection or existing local area connection.
• A computer with a network connection (wired or wireless) and a good web browser. The
screenshots in this manual were taken with Firefox, but Netscape and Internet Explorer
are also supported in versions 4.5 or later, and Safari 1.0 and later are supported with
Macintosh OS X 10.2 and later.
AirStation WZR-AG300NH Package Contents
The AirStation WZR-AG300NH package contains the following items:
• WZR-AG300NH AirStation
• AC adapter and power cable
• CAT5 LAN cable
• Utility CD with Manual
• Quick Setup Guides
• Warranty Statement
Introduction
6
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
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
automatically using a DHCP server. The WZR-AG300NH 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
10
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
25.
11
This is the opening page of your
AirStation’s conguration tool. You
can always get to it from within the
conguration screens by clicking on
Home. From here, you can congure
port mapping for your internet games,
turn on UPnP for Windows (MSN)
Messenger, congure your Firewall,
setup Encryption, choose your Wireless
channel, update your AirStation’s
rmware, and reset your Internet
connection’s conguration. As you
explore the conguration 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.
Home
12
AOSS
AOSS (AirStation One-Touch Secure System) is a simple system for conguring
your wireless network securely. If your router and your client device are
installed and both support AOSS, then making a secure wireless connection
between them 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 ash amber. You now have two minutes
to push the AOSS button on your client device and nish 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
button.
After you’ve pressed both buttons, it will take about 15 seconds for the connection to
complete. When it’s nished, the AOSS light witll glow a solid amber. You now have a
secure network connection!

13
Some things to keep in mind with AOSS:
• Only one AOSS wireless client adapter can be congured 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 congured via AOSS,
unless signicant changes have been made to the wireless network.
• Do not attempt to congure two separate AOSS networks at the same time, as it may
cause undesired congurations.
• If an undesired client has connected via AOSS, it can be disconnected from within the
WZR-AG300NH’s advanced conguration menus.
AOSS Notes
14
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
192.168.11.1 to 192.168.11.100, 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, or conguring your AirStation as part of a bridge setup. It is not
suitable for most home congurations. 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, ip the switch to BRI.

select the type of wireless encryption you’d
like to use. Your AirStation supports three
different encryption schemes; choose the best
one that all your clients support.
Virtually all wireless clients support WEP. It’s
a lot better than nothing.
TKIP is much more secure than WEP, but
slower.
AES is even more secure than TKIP, and the
fastest of all. Highly recommended if all of
your wireless clients support it.
22
This page is available from Home by
selecting Wireless channel. With Auto
Channel selected, your AirStation will
choose the best channel available.

AOSS
41
The SSID or network name can be changed
by entering a custom SSID and pressing
the Apply button.
802.11a (Basic)
42
If you have a mixed mode network,
with Draft-N, 802.11a clients, it’
s recommended that you check 11n
protection to ensure that slower 11a
clients connect properly.
802.11a (Advanced)
43
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
secure.
• 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.
802.11a (Security)
By default, the AirStation broadcasts its SSID. This makes it easier for clients to connect
to the AirStation. To disable broadcasting, uncheck this box.
Privacy Seperator prevents wireless clients from being able to browse each other’s
computers. Check Enable to turn it on.
44
The SSID is the name of your wireless
network. This is what you’ll see
when performing a wireless scan or
survey from a wireless client. You
may change this to something easy to
remember, like “MYNETWORK”.
Channel Selection - You may nd it
necessary to change the AirStation’s
channel to avoid interference with
other 2.4 Ghz sources, such as
cordless phones, neighboring Wi-Fi
networks, baby monitors, etc. By
default, the Auto Channel mode will
attempt to locate the clearest channel
possible.
Channel Bonding modes are specic for Draft-N. The 20 MHz mode uses less
available wireless bandwith, which results in less interference to other 2.4 GHz
wireless devices as well as slower wireless transfer speeds. The 40 MHz mode
uses more bandwith, resulting in potentially more interference but signicantly
more performance. Control Sideband instructs the AirStation to use channels
towards the lower end of the spectrum or the higher end.
802.11g (Basic)
45
If you have a mixed mode network, with
Draft-N, 802.11b and 802.11g clients,
it’s recommended that you check 11n
protection to ensure that slower 11b and
11g clients connect properly.
Choosing Auto for Wireless mode lets
Draft-N, 802.11b and 802.11g clients
connect to the network. If you would
prefer to allow only one of the modes to
connect, you have those options as well.
802.11g (Advanced)
46
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
secure.
• 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.
802.11g (Security)
By default, the AirStation broadcasts its SSID. This makes it easier for clients to connect
to the AirStation. To disable broadcasting, uncheck this box.
Privacy Seperator prevents wireless clients from being able to browse each other’s
computers. Check Enable to turn it on.
47
MAC Access Limit
To setup a bridge between two or more
wireless access points, select Enable
and click on Apply.
48
MAC Access Limit (Edit Registration List)
You may limit access to your wireless
network to specic computers.
