1.1 Overview

This User's Guide covers the following models: NWA5121-N, NWA5121-NI, and NWA5123-NI. Your
NWA is a wireless AP (Access Point). It extends the range of your existing wired network without
additional wiring, providing easy network access to mobile users.

You can set the NWA to operate in either standalone AP or managed AP mode. When the NWA is in
standalone AP mode, it can serve as a normal AP, as an RF monitor to search for rouge APs to help
eliminate network threats, or even as a root AP or a wireless repeater to establish wireless links
with other APs in a WDS (Wireless Distribution System). A WDS is a wireless connection between
two or more APs.
Your NWA's business-class reliability, SMB features, and centralized wireless management make it
ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and
VLAN to provide simultaneous independent virtual APs. Additionally, innovations in roaming
technology and QoS features eliminate voice call disruptions.
The NWA controls network access with Media Access Control (MAC) address filtering, and rogue
Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE
802.1x, Wi-Fi Protected Access (WPA), WPA2 and Wired Equivalent Privacy (WEP) data encryption.
