One-Push Configuration using AOSS or WPS allows you to configure a wireless network easier than configuring it manually. By pushing a button on the wireless router or access point, information is transmitted and automatically configured for wireless network devices.
AOSS (AirStation One-Touch Secure System) is a system by Buffalo Technology which allows a secure wireless connection to be set up with the push of a button. AirStation residential gateways incorporated a button on the unit to let the user initiate this procedure.
How do I enable AOSS?
Press Network. Press WLAN. Press SES/WPS/AOSS. This feature will automatically detect which mode (SecureEasySetup™, Wi-Fi Protected Setup™ or AOSS™) your access point uses to configure your machine.
