Chapter 1: Introduction
Thank you for choosing the Wireless-G Business Ethernet
Bridge.
The Linksys WET200 Wireless Bridge seamlessly bridges
separate Ethernet networks together wirelessly and is
ideal for small businesses with offices and resources that
are in different office suites of a building or a closely
adjacent building. The WET200 is a Power over Ethernet
(PoE) end device so it can be installed anywhere an
Ethernet cable can be run if there is not ready access to
a power outlet. PoE enables delivery of both data and
power to the WET200. An AC adapter is also included if
the device installation site has a power outlet nearby.
Advanced security features include Wi-Fi Protected
Access™ (WPA2 Enterprise) with up to 256-bit AES
encryption using EAP (Extensible Authentication
Protocol) giving small businesses the protection they
need to communicate and transfer data securely. The
integrated QoS features provide consistent voice and
video quality on both the wired and wireless networks,
enabling the deployment of business qualilty VoIP and
video applications.
Introduction
Additional support for VLANs, SNMP, Spanning Tree, and
Port Mirroring make this an ideal solution for network
administrators to incorporate into larger organizations.

Planning Your Wireless Network
Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped
with one or more wireless adapters. Computers in a
wireless network must be configured to share the same
radio channel to talk to each other. Several PCs equipped
with wireless cards or adapters can communicate with
each other to form an ad-hoc network without the use of
an access point.
Linksys wireless adapters also provide access to a wired
network when using an access point or wireless router.
An integrated wireless and wired network is called an
infrastructure network. Each wireless PC in an infrastructure
network can talk to any computer in a wired or wireless
network via the access point or wireless router.
An infrastructure configuration extends the accessibility
of a wireless PC to a wired network, and may double the
effective wireless transmission range for two wireless
adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an
infrastructure network may be doubled (depending on
antenna characteristics).
Example of WET200 in Infrastructure Mode
Network Layout
The Wireless-G Business Ethernet Bridge can be used
in either Infrastructure mode or Ad-Hoc mode. In
Infrastructure mode, the WET200 can be used to bridge
a separate Ethernet segment wirelessly to the company
network backbone. In Ad-Hoc mode, the WET200
communicates directly with other wireless devices, much
like a wireless client card. The WET200 has been designed
for use with 802.11g and 802.11b products, such as the
WAP200 Wireless-G Access Point, in addition to various
wireless adapters for notebook and desktop PC.
Go to the Linksys website at www.linksys.com for more
information about wireless products.
Example of WET200 in Infrastructure Mode
The above diagram shows a typical infrastructure wireless
network setup where the WET200 is being used to manage
multiple VLANs, with one VLAN connected wirelessly to
the company network and Internet. In this example, the
WET200 is connected to a wireless Access Point, which is
in turn connected to the network backbone.

Example of WET200 in Ad-Hoc Mode
Planning Your Wireless Network
Example of WET200 in Ad-Hoc Mode
The WET200 can also be used to quickly set up a temporary
network, as shown above. The diagram shows three wired
networks, Office One, Office Two, and Office Three, each
with a direct connection to the other wired networks via
an Ad-Hoc network connection. The Bridge in Office One is
connected to a Linksys switch that provides power to the
Bridge. In this example, a DHCP server is set up to assign IP
addresses automatically, since the WET200 does not have
a built-in DHCP server. Alternatively, static IP addresses
can be used.

RESET Press and hold the Reset button for
approximately ten seconds to reset the Bridge
to the factory default settings.
ETHERNET 1-5 These RJ-45 ports support
network speeds of either 10 Mbps or 100 Mbps,
and can operate in half and full-duplex modes.
Auto-sensing technology enables each port to
automatically detect the speed of the device
connected to it (10 Mbps or 100 Mbps), and
adjust its speed and duplex accordingly.
Port 5 also supports the IEEE 802.3af Powerover-Ethernet (PoE) PD standard that enables
DC power to be supplied to the Bridge using
wires in the connecting twisted-pair cable. This
allows the Bridge to draw power directly from
the Ethernet cable without requiring its own
separate power source. If a PoE power source
is not available, you can use the supplied AC
power adaptor.
To connect a device to a port, you need to use
Category 5 (or better) network cable.
POWER The Power port is where you connect
the AC power. This port is not used if you are
using Power over Ethernet (PoE) to supply
power through the Ethernet cable.

Quick Configuration Overview
Chapter 5: Quick Configuration Overview
Overview
The Ethernet switch of the WET200 is designed to be
functional right out of the box with the default settings.
In order to use the wireless bridge function, however, you
must first perform a minimal configuration on the Bridge
so that it can find and communicate with the access point.
The Bridge can be configured through your web browser
with the web-based utility. This chapter explains how to
use the utility.
The utility can be accessed via web browsers, such as
Microsoft Internet Explorer or Mozilla Firefox through the
use of a computer that is networked with the Bridge.
For a basic network setup, most users only have to use the
following screens of the Utility:
Setup • The Setup screen is the first screen displayed.
Enter your basic network settings (IP address) here to
allow your PC to access the web-based utility.
NOTE: If your network backbone has a
DHCP server, you must first create a wireless
connection between the bridge and the access
point before you attempt to configure DHCP.
Otherwise, the bridge will not be able to obtain
an IP address and the web-based utility will
be inaccessible. For information on how to
create the wireless connection, see Chapter 6,
“Advanced Configuration.”
Password • Click the Administration tab, then select
the Password sub tab. The Bridge’s default password
is admin. To secure the Bridge, change the Password
from its default.
Wireless • Click the Wireless tab to access the Wireless
screen to configure a wireless connection. This is most
easily done using the Site Survey feature. Click Site
Survey, then select your wireless network’s access
point from the list. If you are prompted for security
settings, enter the requested information (such as
passphrase or shared secret), The wireless bridge will
now be connected to the access point.
Accessing the Web-Based Utility
To access the web-based utility, perform these steps:
Configure your PC with a static IP address in the 1.
same subnet as the Bridge’s default IP address,
192.168.1.226. If a DHCP server is to be connected
to the switch, configure it to assign the IP address in
subnet 192.168.1.0/24. Your PC will get an IP address
in the subnet through the DHCP.
Launch your web browser, such as Internet Explorer 2.
or Mozilla Firefox, and enter the Bridge’s default IP
address, 192.168.1.226, in the Address field. Press the
Enter key.
Enter 3. admin in the User Name field. The first time
you open the web-based utility, use the default
password, admin. (You can set a new password from
Administration > Password) Then click OK.
When you are finished setting up the Bridge’s IP address,
either by manually assigning it a new IP address or by
configuring it to use DHCP, move your Bridge to the
desired network. You will have to use the new IP address
the next time you access the web-based utility.
Navigating the Web-Based Utility
The web-based utility consists of the following five main
tabs: Setup, Wireless, Switch, Administration, and
System Status. Additional screens (sub tabs) will be
