14USING 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.◗ Confi gure your WLA2-G54C’s network connection by referring to the above mentioned instructions.◗ Once the WLA2-G54C has been confi gured, follow the directions to install your wireless client device and its drivers if necessary. Certain wireless client adapters require client software to confi 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 BridgesClient Manager Devices: CardBus, USB, and PCI Adapters.StandaloneAOSS DeviceClient ManagerDevice◗ Now that the WLA2-G54C and wireless client adapter are installed, you can use AOSS to confi gure them.◗ To begin the confi guration, press the AOSS button in the WLA2-G54C’s confi guration. The AOSS menus can be found under the ‘Advanced’ Confi guration, Management, AOSS. The status screen will briefl y show that it is in AOSS mode. The WLA2-G54C’s 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 adapter’s AOSS supplement to initiate the wireless client adapter’s 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 confi 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 signifi 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 confi gurations.◗ If an undesired client has connected via AOSS, it can be disconnected from within the WLA2-G54C’s advanced confi guration AOSS menus.ADDITIONAL INFORMATIONPlease check the Buffalo Web site for the latest information and any corrections done for this manual.For more information, please consult one of the following:• The on-line help system of your AirStation wireless system - for in for ma tion about software and driver func tion al ity. • The AirStation website at our local website indicated last page.- for frequently asked questions (FAQ’s) and Software Updates.
