Getting Started
1.1 Overview
The ZyXEL NWD2205 wireless N USB adapter brings you a better Internet
experience over existing IEEE 802.11 b/g/n networks. With data rates of up to
300 Mbps, you can enjoy a high-speed connection at home or in the office. It is an
excellent solution for daily activities such as file transfers, music downloading,
video streaming and online gaming.
1.1.1 What You Need to Know
The following terms and concepts may help as you read through this section, and
subsequently as you read through the rest of the User’s Guide.
Access Point
An Access Point (AP) is a network device that acts as a bridge between a wired
and a wireless network. Outside of the home or office, APs can most often be
found in coffee shops, bookstores and other businesses that offer wireless
Internet connectivity to their customers.
Infrastructure
An infrastructure network is one that seamlessly combines both wireless and
wired components. One or more APs often serve as the bridge between wireless
and wired LANs.
Ad-Hoc
An Ad-Hoc wireless LAN is a self-contained group of computers connected
wirelessly and which is independent of any other networks and Access Points.
1.1.2 Before You Begin
Read the Quick Start Guide for information on making hardware connections and
using the ZyXEL utility to connect your NWD2205 to a network.
