Welcome

Wireless-G Ethernet Bridge with 5-Port Switch

Chapter 1: Introduction

Welcome

Thank you for choosing the Wireless-G Ethernet Bridge with 5-port Switch. The Wireless-G Ethernet Bridge with

5-port Switch can make any wired Ethernet-equipped device a part of your wireless 802.11b or 802.11g network.

At home, use the Bridge to connect game consoles or computers to your Wireless-G network and its shared high-

speed Internet connection.

In the office, convert your Ethernet-wired printer, camera, notebook or desktop into a

wireless networked device.

The Wireless-G Ethernet Bridge with 5-port Switch can be used for connecting remote areas together. You can

connect up to 5 Ethernet-equipped computers directly to the high-speed 10/100 switch ports on the Wireless-G

Ethernet Bridge.

Put another one (or a Wireless-G Access Point, or our one-port Wireless-G Ethernet Bridge) at

the other end, and those 5 computers are connected to your main network.

And those 5 switch ports can support devices other than PCs.

Since there are no drivers to load, you can make

any wired-Ethernet device, such as a printer or network attached storage device, into a wireless network device.

All five ports are auto-speed negotiating, and have automatic MDI/MDI-X crossover detection, so you don't have

to worry about the cable type.

To protect your data and privacy, all wireless transmissions can be secured with

up to 128-bit WEP encryption, Pre-Shared Key, or RADIUS.

Use the instructions in this Guide to help you set up and connect the Wireless-G Ethernet Bridge with 5-port

Switch. These instructions should be all you need to get the most out of the Wireless-G Ethernet Bridge with

5-port Switch.

Ethernet

: an IEEE standard network

protocol that specifies how data is

placed on and retrieved from a

common transmission medium.

802.11g

: an IEEE wireless networking

standard that specifies a maximum

data transfer rate of 54Mbps, an

operating frequency of 2.4GHz, and

backward compatibility with 802.11b

devices.

Network Topology

Wireless-G Ethernet Bridge with 5-Port Switch

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each

computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same

frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the

same wireless network.

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. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an

access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.

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 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 2-1). Access points transmit data to PCs equipped with

wireless network cards, 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.

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, wireless-equipped computers are not able to communicate with

computers on a wired network. And, of course, communication between the wireless-equipped computers is

limited by the distance and interference directly between them.

Figure 2-2 shows a typical scenario of four Wireless-G Ethernet Bridges in ad-hoc mode. Figure 2-3 shows a

typical wireless bridging scenario using two Wireless-G Ethernet Bridges. Each wireless network is connected to

a Wireless-G Ethernet Bridge through a switch. A separate notebook computer is equipped with a wireless

network adapter and can communicate with either wireless network when it is configured with the appropriate

SSID and channel.

SSID

: your wireless network’s name.

LAN

(Local Area Network)

: the

computers and networking products

that make up your local network.

Figure 2-1: Infrastructure Network

Infrastructure

: a wireless network

that is bridged to a wired network via

an access point.

Ad-hoc

: a group of wireless devices

communicating directly to each other

(peer-to-peer) without the use of an

access point.
