Introduction
This chapter introduces the features, package contents, and appearance of the NETGEAR 11 Mbps
Wireless USB Adapter MA111.
About the MA111
The NETGEAR 11 Mbps Wireless USB Adapter MA111 gives you ultimate mobility in your
office or while you are traveling. It frees you from traditional Ethernet wiring and helps you create
a wireless network for sharing your broadband Internet access among multiple PCs in and around
your home. It is designed for PC computers running Microsoft®Windows®. It is a USB 1.1 device
and is compatible with USB 2.0 ports.
Its auto-sensing capability allows high packet transfer at up to 11 Mbps for maximum throughput
or dynamic range shifting to lower speeds due to distance or operating limitations in an
environment with a lot of electromagnetic interference.
The MA111 Wireless USB Adapter provides reliable, standards-based 802.11b 11 Mbps WLAN
connectivity that is protected with industry-standard security. It works with Windows 98SE, Me,
2000, and XP operating systems.
Key Features
The MA111 Wireless USB Adapter provides the following features:
• Reliable IEEE 802.11b standards-based wireless technology.
• 11 Mbps high speed data transfer. Wireless nodes negotiate to operate in the optimal data
transfer rate. In a noisy environment or when the distance between the wireless nodes is far,
the wireless nodes automatically fall back to operate at lower transfer rates.
• High level of data encryption using128-bit Shared Key WEP data encryption method. A lower
level of data encryption or no data encryption is available to simplify your network setup or to
improve data transfer rate.

A Road Map for ‘How to Get There From Here’
The introduction and adoption of any new technology can be a difficult process. Wireless
technology has removed one of the barriers to networking—running wires. It allows more people
to try networking while at the same time exposes them to the inherent complexity of networking.
General networking concepts, setup, and maintenance can be difficult to understand. In addition,
wireless technology adds issues, such as range, interference, signal quality, and security to the
picture.
To help overcome potential barriers to successfully using wireless networks, the table below
identifies how to accomplish such things as connecting to a wireless network, assuring appropriate
security measures are taken, browsing the Internet through your wireless connection, exchanging
files with other computers and using printers in the combined wireless and wired network.

Chapter 3
Basic Setup
This chapter describes how to install your NETGEAR 11 Mbps Wireless USB Adapter MA111
and set up basic wireless connectivity on your Wireless Local Area Network (WLAN). Advanced
wireless network configuration is covered in Chapter 4, “Configuration” in this manual.
What You Need Before You Begin
You need to verify your computer meets the minimum system requirements and identify the
wireless network configuration settings of the WLAN where you will connect before you can
configure your wireless USB adapter and connect.
Verifying System Requirements
Before installing the NETGEAR 11 Mbps Wireless USB Adapter MA111, please make sure that
these minimum requirements have been met:
• You must have a PC with a Pentium®300 MHz or higher compatible processor with an
available USB 2.0 or 1.1 port.
•ACD-ROMdrive.
• 5 Mbytes of free hard disk space.
• Windows XP Home, Windows XP Professional, 2000, Me, or 98SE. Some versions of
Windows may ask for the original Windows operating system installation files to complete the
installation of the MA111 driver software.
Note: Indoors, computers can easily connect to 802.11 wireless networks at distances
of several hundred feet. Because walls do not always block wireless signals, others
outside your immediate area could access your network. It is important to take
appropriate steps to secure your network from unauthorized access. The NETGEAR 11
Mbps Wireless USB Adapter MA111 provides highly effective security features which
are covered in “Enabling Wireless Security Features” on page 4-5 in this manual.
Deploy the security features appropriate to your needs.

3-2 Basic Setup
202-10032-01
Observing Location and Range Guidelines
Computers can connect over wireless networks indoors at a range which vary significantly based
on the physical location of the computer with the NETGEAR 11 Mbps Wireless USB Adapter
MA111. For best results, avoid potential sources of interference, such as:
• Large metal surfaces
•Microwaves
• 2.4 GHz Cordless phones
In general, wireless devices can communicate through walls. However, if the walls are constructed
with concrete, or have metal, or metal mesh, the effective range will decrease if such materials are
between the devices.
Two Basic Operating Modes
The MA111 Wireless USB Adapter can operate in the following two basic modes:
•Infrastructure Mode: An 802.11 networking framework in which devices and computers
communicate with each other by first going through an access point (AP). For example, this
mode is used when computers in a house connect to an Access Point that is attached to a router
which lets multiple computers share a single Cable or DSL broadband Internet connection.
•Ad-Hoc Mode:An 802.11 networking framework in which devices or computers
communicate directly with each other, without the use of an AP. For example, Ad-Hoc Mode
is used when two Windows computers are configured with file and print sharing enabled and
you want to exchange files directly between them.
Both of these configuration options are available with the MA111 Wireless USB Adapter.
Infrastructure configuration procedures for basic network connectivity are covered below.
Advanced infrastructure configuration procedures and ad-hoc configuration are covered in
Chapter 4, “Configuration” of this manual.
