PlanningYourWirelessNetwork
Network Topology
A wireless LAN is a group of computers, each equipped with one Instant
Wireless™ Network Card. Computers in a wireless LAN must be configured
to share the same radio channel.
The Instant Wireless™ Network Card provides access to a wired LAN for wire-
less workstations. An integrated wireless and wired LAN is called an
Infrastructure configuration. A group of Instant Wireless™ Network Card
users and an Instant Wireless™ NetworkAccess Point compose a Basic Service
Set (BSS). Each Instant Wireless™ Network Card 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™ Network Card PC to a wired LAN, and doubles the effective wire-
less transmission range for two Instant Wireless™ Network Card 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™ Network
PC Card 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™ Network PC Card 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.

Dipole Antenna
Connectors These two round connections are where the anten-
nas are connected to the Access Point.
LAN This LAN (Local Area Network) port connects to
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 connects to the
USB port on the rear panel of your Wireless Network Access 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.

which the sender and the recipient do NOT share a secret key. Each party
generates its own key-pair and asks the receiver to accept the randomly-
generated key. Once accepted, this key is used for a short time only. Then
a new key is generated and agreed upon. Even if this secret key is discov-
ered, only a small amount of data may be deciphered. Shared Key is when
both the sender and the recipient share a secret key. They use this key for
an extended length of time, sometimes indefinitely. Any eavesdropper who
discovers the key may decipher all packets until the key is changed.

DEFAULT SETTINGS:
The default IP Address is: 192.168.1.250
The default SubNet Mask is: 255.255.255.0
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.

NetworkAccess Point is disconnected, you can reconnect the Ethernet cable
and click the Reconnect button here. This will retrieve all of the data from
the Wireless Network Access Point so you will be ready to use the Access
Point SNMP Configuration Utility again.
• Restore Defaults. Click this button to restore the Wireless NetworkAccess
Point’s default settings. Any setting you may have made through the Access
Point SNMP Configuration Utility will be lost if this button is clicked.

THE ADVANCED TAB
Before making any changes to the Advanced tab, please check your wireless
settings as these changes will alter the effectiveness of the Wireless Network
Access Point. In most cases, these settings do not need to be changed.
• Fragmentation Threshold Value. This value indicates how much of the
Access Point’s resources are devoted to recovering packet errors. The value
should remain at its default setting of 2,346. If you have decreased this
value and experience high packet error rates, you can increase it again, but
it will likely decrease overall network performance. Only minor modifica-
tions of this value are recommended.
• RTS Threshold Value. This value should remain at its default setting of
2,346. Should you encounter inconsistent data flow, only minor modifica-
tions are recommended.
• Authentication Type. The authentication type defines configuration
options for the sharing of wireless networks to verify identity and access
privileges of roaming wireless network cards. Verify that you’ve set this to
the correct authentication type before clicking the Apply button.
• Preamble Type. The preamble defines the length of the CRC block for
communication between the Wireless Network Access Point and the roam-
ing wireless network card. Verify that you’ve selected the appropriate pre-
amble type before clicking the Apply button.

THE BASIC SETTINGTAB
The Wireless Network Access Point will automatically detect the settings to
your wireless network. Changing these values will alter your current wireless
network configuration.
• ESSID. The ESSID or SSID is the unique name shared among all points in
a wireless network. The ESSID must be identical for all points in the net-
work. It is case sensitive and must not exceed 30 characters. Make sure that
all points in the network are set the same. Verify that you’re using the cor-
rect ESSID before clicking the Apply button.
• Channel. Select the appropriate channel from the list provided to corre-
spond with your network settings, between 1 and 11 (in North America).
All devices that communicate with this Access Point must use the same
channel in order to work correctly. Verify that the correct channel is select-
ed before clicking the Apply button.
The Close button will close the SNMP Configuration Utility without saving
any changes.
Click the Apply button to store the information, then click the Yes button to
accept the changes in the dialog box that appears.

• Basic Rates. The basic transfer rates should be set depending on the speed
of your wireless network. Older, slower wireless networks should be set at
1-2 (Mbps) while a faster wireless network should be set at 1-2-5.5-11
(Mbps). Verify that you’ve set the correct basic rate for your wireless net-
work before clicking the Apply button.
•The Auto Rate Fall Back setting should be checked to make your wireless
network flexible to roaming wireless devices. As wireless devices move
away from the Wireless Network Access Point, the transfer rate will auto-
matically fall back to the most optimum rate allowed.
• Operational Mode
by default is set to
Access Point. This is
for connecting your
wireless PCs to a
wired network. In
most cases, no change
is necessary to this
default setting.
If you are trying to
make a wireless con-
nection between two
wired networks, select
Wireless Bridge. If
you are connecting to
another Access Point,
select Point to Point
and enter in the apro-
priate Remote MAC
Address (this address
must be identical to
the other Access
Point’s MAC
address).

THE IP SETTING TAB
The IP settings for the Wireless Network Access Point are made from this tab.
This is for SNMP Configuration Utility use only.
• IP Address. The IP address assigned here must be unique to your network.
We suggest that you use the default IP address of 192.168.1.250. As this is
a private IP address, you do not need to purchase an additional IP address
from your service provider. Verify that it is set to the correct IP address and
click the Apply button to save the changes.
• IP Mask. Your Subnet Mask must be the same as your Ethernet Network.
Verify that this is set to the correct Subnet Mask or click the Apply button
to set it, and then Yes to accept the changes.
The DHCP settings are also made from this tab. Check the box next to DHCP
Enable to allow it to obtain a dynamic IP address from a DHCP server. You
may also choose how the Wireless Network Access Point is to dynamically
obtain an IP address—either via Wireless or Ethernet. No DHCP changes
will take effect until the Access Point has been powered down and powered up
again.
