Chapter 1 - Product Overview
Features
Supports IEEE802.11n and IEEE802.11b/g
With support for Wireless-N, Wireless-G, and Wireless-B standards, the AirStation can transfer data to
and from all standard 2.4 GHz wireless clients.
Supports WDS
WDS bridging allows multiple units to operate in a bridged network for extended coverage.
Dual speed mode
Dual speed mode makes wireless transmission faster by using 2 channels, allowing 150 Mbps data
transmission.
Support AOSS and WPS
Both AOSS (AirStation One-touch Secure System) and WPS (Wi-Fi Protected Setup) are supported.
These automatic connection standards make connection with compatible wireless devices easier.
Security Features
The AirStation is equipped with the following security features:
• AOSS
• WPS
• WPA-PSK (TKIP/AES)
• WPA2-PSK(TKIP/AES)
• WPA/WPA2 mixed PSK
• WEP(128/64 bit)

Chapter 1 Product Overview
Initialization
To restore settings back to the factory defaults, hold down the Reset button on the bottom of the
unit.
Browser Based Administration
This unit can be easily congured from a web browser on your computer.
Air Navigator CD Requirements
The AirStation wireless router and access point works with most wired and wireless devices. The
automatic installation program on the CD requires Windows 7, Vista or XP to run. Client Manager
software is included for Windows 7, Vista and XP. The use of other operating systems may require
that the AirStation be manually congured from a browser window.
150 Mbps High Speed Mode
150 Mbps is the link speed of WCR-GN when using Wireless-N mode. It represents actual wireless
data speeds, including overhead. Because the overhead is not available for user data transfer, usable
wireless throughput will be substantially slower.
