USING 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 a Buffalo
AOSS enabled wireless client device to use the AOSS features of your AOSS Access Point/Router.
The INIT switch initiates AOSS mode now. If you want to restore the factory default settings, hold the INIT switch up to 5 seconds
when turn the unit on.
Con gure your WLA2-G54Cs network connection by referring to the above mentioned instructions.
Once the WLA2-G54C has been con gured, follow the directions to install your wireless client device and its drivers if necessary.
Certain wireless client adapters require client software to con 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 WLA2-G54C and wireless client adapter are
installed, you can use AOSS to con gure them.
To begin the confi guration, press the AOSS button in the WLA2-
G54Cs con guration. The AOSS menus can be found under the
AdvancedConfi guration, Management, AOSS. The status screen
will brie y show that it is in AOSS mode. The WLA2-G54Cs
Wireless Light may turn on and off.
NOTE: AOSS mode will stay active for a period of two
minutes. This is the time-slot required to initiate the wireless
client adapter.
Refer to your wireless client adapters AOSS supplement to initiate the wireless client adapters AOSS mode.
Once the client adapter has begun communicating with the AOSS router, AOSS client will report a successful AOSS connection.
This indicates that the AOSS process has begun and the two devices are con guring themselves. Please refer to your wireless client
adapter’s supplement for the remainder of the setup.
ADDITIONAL AOSS INFORMATION:
Only one AOSS wireless client adapter can be confi gured to the AOSS access point 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 reconfi gure AOSS client devices that have already been confi gured via AOSS, unless signi 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 con gurations.
If an undesired client has connected via AOSS, it can be disconnected from within the WLA2-G54C’s advanced confi guration
AOSS menus.

• In Open Office environments, clients can “see” each other, i.e.
there are no physical obstructions between them.
In Semi-open Office environments, work space is separated by
room dividers; client cards are at desktop level.
In Closed Office environments, workspace is separated by
floor-to-ceiling brick walls.
NOTE:
The range values listed in Table “Radio Characteristics” are
typical distances as measured at Buffalo Technology AirStation
laboratories. These values are provided for your guidance but
may vary according to the actual radio conditions at the location
where the AirStation product is installed.
