Wireless Ethernet Bridge

Chapter 1: Introduction

The Wireless Ethernet Bridge

The versatile Wireless Ethernet Bridge can make any wired Ethernet-equipped device a part of your wireless network. At home, use the Wireless Ethernet Bridge to connect to game consoles, set-top boxes, or computers into your wireless network to share your high-speed network connection. In the office, convert your Ethernet-wired printer, scanner, camera, notebook, or desktop into a wireless networked device.

It’s completely driver-free, so it works on any platform and under any operating system! Since there are no drivers to load, setup is a snap—just plug it into your device and configure the network settings through your web browser.

You can also use the Wireless Ethernet Bridge as a kind of “cable-less cable” to connect remote areas together. Maybe Shipping is all the way across the warehouse from Receiving. Or maybe you want to set up a home office in your detached garage. With a Wireless Ethernet Bridge in the garage, and another one (or a Wireless Access Point) in the house, you’re connected—with no cabling hassle.

Chapter 3: Planning Your

Wireless Network

Network Topology

A wireless LAN is exactly like a regular LAN, except that each network device in the LAN uses a Wireless Ethernet Bridge to connect to the network without using wires. Computers in a wireless LAN must be configured to share the same radio channel.

The Wireless Ethernet Bridge provides LAN access for wireless network devices. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of Wireless Ethernet Bridge users and an access point compose a Basic Service Set (BSS). Each PC equipped with an Wireless Ethernet Bridge in a BSS can talk to any computer in a wired LAN infrastructure via the Bridge.

An infrastructure configuration extends the accessibility of a Wireless Ethernet Bridge to a wired LAN, and doubles the effective wireless transmission range for two Wireless Ethernet Bridge PCs. Since the 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 Basic Service Set is essential.

The Wireless LAN infrastructure configuration is appropriate for enterprisescale wireless access to a central database, or as a wireless application for mobile users.

Roaming

Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All Wireless Ethernet Bridge PCs within one Extended Service Set must be configured with the same SSID.

Selecting a feasible radio channel and optimum access point position is recommended. Proper access point positioning combined with a clear radio signal will greatly enhance performance.

Wireless Ethernet Bridge

Ad-Hoc versus Infrastructure Mode

Unlike wired networks, wireless networks have two different modes in which they may be set up: Infrastructure and Ad-Hoc. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral, such as a printer, with the wired network computers, the wireless network should be set up in the Infrastructure mode. The basis of Infrastructure mode centers around an access point, which serves as the main point of communications in a wireless network (see Figure 3-1). Access points transmit data to PCs equipped with wireless network card, which can roam within a certain radial range of the access point. Multiple access points can be arranged to work in succession to extend the roaming range, and can be set up to communicate with your Ethernet hardware as well.

Figure 3-1

Figure 3-2

Instant Wireless® Series

If the wireless network is relatively small and needs to share resources only with the other computers on the wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. The drawback of this mode is that in Ad-Hoc mode, wire- less-equipped computers are not able to communicate with computers on a wired network. And, of course, com-

munication between the wireless-equipped computers is limited by the distance and interference directly between them.

Figure 3-2 shows a typical scenario of four Wireless Ethernet Bridges in ad-hoc mode. Figure 3-3 shows a typical wireless bridging scenario using two Wireless Ethernet Bridges. Each wireless network is connected to a Wireless Ethernet Bridge through a switch. A separate notebook computer is equipped with a wireless PC card and can communicate with both wireless networks as long as it has the same SSID and channel as both wireless networks.

Chapter 4: Connecting the

Wireless Ethernet Bridge

1.Plug the included Ethernet network cable into the LAN port on the back panel of the Bridge.

Figure 4-1

2.The X-II selection switch offers a choice between two settings. Slide the X-II selection switch to the X position if you are connecting the Bridge to a network card or other Ethernet device. Slide the X-II selection switch to the II position if you are connecting the Bridge to a hub or switch.

3.Plug the other end of the Ethernet network cable into the RJ-45 port on the PC you wish to use to configure the Bridge.

4.Plug the supplied power cable into the Power port on the back panel of the Bridge. Then plug the other end into an electrical outlet.

5.Proceed to the next section, “Chapter 5: Setting Up the Wireless Ethernet Bridge.”

6.After configuration, unplug the Ethernet network cable from the PC, and plug it into the RJ-45 port on the Ethernet-ready network device you wish to add to the wireless network.

The hardware installation is complete.

2.The screen shown in Figure 5-2 shows the two ways to configure the Bridge using this Setup Wizard. Optimally, you should perform this setup through a PC on your wired network. You can also set up the Bridge through one of the PCs on your wireless network. Click the Next button to continue or the Exit button to exit the Setup Wizard.

Figure 5-2

3.The screen shown in Figure 5-3 displays a list of Wireless Ethernet Bridges on your network, along with the status information for each Bridge. (If you have only one Bridge on your network, it will be the only one displayed.) Select the Bridge you are currently installing by clicking its name in the Selection box. Write down the IP address of the Wireless Ethernet Bridge, so you can use it to access the Web-based Utility later. Click the Yes button to continue or the Exit button to exit the Setup Wizard.

Figure 5-3

Instant Wireless® Series

4.For security purposes, you will be asked for your user name and password in order to access the Bridge. In lowercase letters, enter admin in the Password field (later you can change the password through the Web-based Utility). Click the Yes button to continue or the No button to return to the previous screen.

Figure 5-4

5.The screen shown in Figure 5-5 shows a choice of two wireless modes. Click the Infrastructure Mode radio button if you want your wireless computers to network with computers on your wired network using a wireless access point. Click the Ad-Hoc Mode radio button if you want multiple wireless computers to network directly with each other. Do not use the Ad-Hoc mode if you want to network your wireless computers with computers on your wired network. Click the Next button to continue or the Back button to return to the previous screen.

Figure 5-5

Wireless Ethernet Bridge

6.The Basic Settings screen will now appear. Enter your wireless network’s SSID, and select the Channel at which the network broadcasts its wireless signal. Enter a unique Bridge Name for the Bridge. Then click the Next button to continue or the Back button to return to the previous screen.

•SSID - The SSID is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character (do not use any spaces). Make sure this setting is the same for all points in your wireless network.

•Channel - Select the appropriate channel from the list provided to correspond with your network settings, between 1 and 11 (in North America). All points in your wireless network must use the same channel in order to function correctly.

•Bridge Name - You may assign any name to the Bridge. Unique, memorable names are helpful, especially if you are using multiple bridges on the same network.
