Planning Your Wireless Network
Network Topology
A wireless LAN is a group of computers, each equipped with one Instant
Wireless™ Series Adapter. Computers in a wireless LAN must be configured
to share the same radio channel.
The Instant Wireless™ Series Adapter provides access to a wired LAN for
wireless workstations. An integrated wireless and wired LAN is called an
Infrastructure configuration. A group of Instant Wireless™ Series Adapter
users and an Instant Wireless™ NetworkAccess Point compose a Basic Service
Set (BSS). Each Instant Wireless™ Series Adapter PC in a BSS can talk to any
computer in a wired LAN infrastructure via the Instant Wireless™ Network
Access Point.
An infrastructure configuration extends the accessibility of an Instant
Wireless™ Series Adapter PC to a wired LAN, and doubles the effective wire-
less transmission range for two Instant Wireless™ Series Adapter PCs. Since
the Wireless Network Access Point is able to forward data within its BSS, the
effective transmission range in an infrastructure LAN is doubled.
The use of a unique ID in a BSS is essential. All Instant Wireless™ Series
Adapter PCs configured without roaming options in an independent BSS must
be configured with a BSS ID used in the BSS.
The wireless LAN Infrastructure configuration is appropriate for enterprise-
scale wireless access to a central database, or as a wireless application for
mobile users.
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). This con-
tinuous network allows users to roam freely within an ESS. All Instant
Wireless™ Series Adapter PCs within one ESS must be configured with the
same ESS ID and use the same radio channel.
Before enabling an ESS with roaming capability, choosing a feasible radio
channel and optimum Wireless Network Access Point position is recommend-
ed. Proper Wireless Network Access Point positioning combined with a clear
radio signal will greatly enhance performance.

Getting to Know the Wireless
Network Access Point
The ADSL Modem Router’s Rear Panel
Your Access Point’s ports, where network cables are connected, are located on
the rear panel of your Access Point.
The Wireless Network Access Point’s Ports
Dipole Antenna
Connectors These two round connections are where the anten-
nae are connected to the Access Point.
LAN This LAN (Local Area Network) port connects to
Ethernet network devices, such as a hub, switch, or
router.
Power The Power port is where you will connect the
power adapter. Be sure to connect the power cord to
the power adapter before plugging it in.
Configuration Port The Configuration Port is a USB port (Type B-
slave) which connects to a USB-ready PC in order
to configure the Access Point’s settings. To work
with USB ports, your PC must be running Windows
98, 2000, or Millennium.
4
Your Access Point comes with a USB cable that has two different types of con-
nectors. Type A, the master connector, is shaped like a rectangle and plugs into
your PC’s USB port. Type B, the slave connector, resembles a square and con-
nects to the USB port on the rear panel of your Wireless NetworkAccess Point.
USB Compatibility with Your PC
To use the USB port on the Wireless Network Access Point, you must have
Windows 98, 2000, or Millennium installed on your PC. USB is not support-
ed in a Windows 95 or NT environment.
Also, your PC must have a USB port installed and enabled. Some PCs may
have a disabled USB port. If your port doesn’t seem to be working, there may
be jumpers on the motherboard or a menu option in the BIOS to enable a PC’s
USB port.
Other motherboards have USB interfaces, but no ports. You can install your
own USB port and attach it to your PC’s motherboard using hardware pur-
chased at retail computer stores. See your PC’s User Guide for instructions.
There is no USB Support on PCs
running Windows 95 or Windows NT.

THE SECURITY TAB
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 40 bit
shared key algorithm, as described in the IEEE 802.11b standard. In order to utilize
WEP encryption, all points in your wireless network must have WEP enabled and
be set to the same Key Setting. For easier configuration, it is strongly recommend-
ed that you use the Passphrase feature.
• WEP (Disable/64-bitWEP/128-bitWEP). In order to utilize WEP encryption,
select the WEP setting from the pull-down menu. If you do not wish do utilize
WEP encryption, make sure Disable is selected. This specific WEP encryption
is unique to Linksys and may conflict with other vendors’WEP encryption.
• Passphrase. This is the code used when a point on the wireless network wishes
to log on to the network. It is a text string with a maximum of 32 alphanumeric
characters.The WEP Key Settings are based upon the Passphrase determined by
you. Type that here. This passphrase may not work with non-Linksys products
due to possible incompatibility with other vendors’passphrase generators.
28
Note: For security, it is recommended that you make up your own passphrase
(i.e. “Home”). You must use the same passphrase or WEP key settings for all
wireless computers in order for the wireless network to function properly.

Creating a Temporary IP Address
Linux/Unix Users: Though these operating systems are not supported by
Linksys, the Wireless Access Point should work in these environments. The
WAP11 can be configured under these operating systems using SNMP. A
configurable Management Information Base file (MIB) named
AT76C510.MIB can be found on the Setup Utility CD. This file is for
Linux/Unix users only, and is not necessary for anyWindows installation.
THE INFO TAB
The Info tab displays general information about Linksys and the USB Utility.
The USB Utility’s copyright date and version number are listed as well as the

set up), the email address for technical support, and the phone number to call
for technical support.
Note: Once your Access Point is installed and con-
figured, the USB cable may be removed.
