How to Set Up AirStation for the First Time
Connect to a PC and Power On
To configure your AirStation, follow the procedure below.
1 Verify that you can connect to the Internet without the AirStation, then turn off your modem and computer.
2 Unplug the LAN cable which connects your computer and modem.
3 Plug one end of the LAN cable into your modem and the other end to the AirStation's Internet (WAN) port. Turn
on the modem.

4 Turn on the AirStation and wait one minute.
Note: If the power does not come on when the AC adapter is connected, press the power button on the rear of the
AirStation.
5 If using a wired LAN, connect the AirStation LAN port and computer using a LAN cable.
If using a wireless LAN, connect the computer to the wireless LAN as described in the "Adding an AirStation to an
Existing Wireless Network as a Client" section in chapter 3.
6 Once your computer has booted, the AirStation's LEDs should be lit as described below:
Power: Lit green.
Wireless: Lit green.
Internet access: Lit green.
Router: Lit green.
LAN: Lit or blinking green.
Internet: Lit or blinking green.

Notes:
• The AirStation's default LAN-side IP address depends on the mode.
• In router mode: 192.168.11.1
• In access point mode: 192.168.11.100
• In wireless bridge mode: 192.168.11.100
• If you changed the IP address of the AirStation, then use the new IP address.
3 Enter "admin" for the username and "password" for the password, then click Log In.
Note: If you forget your password, hold down the reset button to initialize all settings. Note that all other settings
will also revert to their default values.

4 This is the home page of Settings, where most AirStation settings can be configured.
Connect Your Wireless Devices
For each wireless device that you want to connect to the network, use the device's built-in software to search for
available networks. Find your SSID (the name of your wireless network) on the list of detected networks and select it.
Enter the passphrase for the network and you'll be connected. Repeat for any additional wireless client devices that you
want to connect.

Chapter 2 - Settings
Settings is the configuration GUI for the AirStation. You can configure all settings for the AirStation from here.
Easy Admin

When you first open Settings, the Easy Admin page is shown. From this page you can easily configure common settings.
The examples below assume the AirStation is in router mode.
Wireless Displays current wireless status. Click the panel to configure wireless settings.
AOSS/WPS Displays current AOSS/WPS status. Click the panel to run AOSS/WPS.

19
Wireless
Configure basic wireless settings here. This is available in router and access point modes only.
2.4 GHz (11n/g/b)
5 GHz (11ac/n/a)
You may enable or disable either wireless frequency range independently. If both
wireless radios are disabled, the AirStation will not communicate wirelessly.
SSID 1 Each SSID may contain up to 32 alphanumeric characters.
Encryption
The following types of encryption are available:
WPA2-PSK AES
WPA2 authentication with AES encryption is the best system available. Highly
recommended if all your wireless clients support it.
WPA-PSK AES
WPA authentication with AES encryption is an older system, but still secure.
WPA/WPA2-mixed PSK TKIP+AES
For maximum compatibility, this system allows any combination of WPA, WPA2, TKIP, and
AES. This encryption system works with most older clients but is not very secure.
No encryption
No encryption means that anyone can log in to your wireless network, snoop on your
wireless traffic, and use your bandwidth. Not recommended for most users.
Encryption Key
The encryption key is like the "password" for your wireless network. It may contain 8 to
63 case-sensitive alphanumeric characters (ASCII) or 64 hexadecimal characters (0-9 and
a-f, not case-sensitive).
Channel For best results, select Auto Channel. The AirStation will seek and use the clearest
channel automatically. Alternately, you may choose a wireless channel manually.
Bandwidth
In rural areas with little wireless traffic, a larger bandwidth setting may improve wireless
performance significantly. However, if you are in an urban area with much wireless traffic
and interference, a smaller bandwidth is recommended.

20
AOSS/WPS
The following window appears when you click the panel. Click OK to start AOSS/WPS.
USB Storage

BuffaloNAS.com Status If the status shows Registration failure, check your BuffaloNAS.com settings.
Username The WebAccess username may contain up to 20 alphanumeric characters, hyphens (-),
underscores (_), and periods (.). Don't use a symbol as the first character.
