Introduction

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.

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

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 infrastructurenetwork.EachwirelessPCinaninfrastructure 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).

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.

Planning Your Wireless Network

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.

Planning Your Wireless Network

Example of WET200 in Ad-Hoc Mode

TheWET200 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.

Product Overview

Back Panel

The reset button, the Ethernet ports, and the power port are located on the back panel of the Bridge.

Back Panel

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 Power- over-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

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.

Quick Configuration Overview

Accessing the Web-Based Utility

To access the web-based utility, perform these steps:

1.Configure your PC with a static IP address in the 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.

2.Launch your web browser, such as Internet Explorer or Mozilla Firefox, and enter the Bridge’s default IP address, 192.168.1.226, in the Address field. Press the

Enter key.

3.Enter 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 available from most of the main tabs.
