Wireless-G Broadband Router with 2 Phone Ports

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Broadband Router. The Wireless-G Broadband Router will allow

you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.

How does the Wireless-G Broadband Router do all of this? A router is a device that allows access to an Internet

connection over a network. With the Wireless-G Broadband Router, this access can be shared over the three

switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-

G. In addition, the WPA standard provides greater security opportunities while the whole network is protected

through NAT technology. All of these security features, as well as full configurability, are accessed through the

easy-to-use browser-based utility.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share

Internet access, so you don’t need more than one high-speed Internet connection. After you set up your babyTEL

account, you can also use your Internet access to make phone calls, even while you’re surfing the Internet.

Plus, you can access one printer from different computers and access data located on another computer’s hard

drive. Networks are even used for playing multiplayer video games. So, networks not only are useful in homes

and offices, but also can be fun.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is

why the network is called “wired”.

PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the

same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called

a WLAN, or Wireless Local Area Network. The Wireless-G Broadband Router bridges wireless networks of both

802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.

With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet

access—and even play games. All the while, the Wireless-G Broadband Router protects your networks from

unauthorized and unwelcome users.

To create your network, install and set up the Router. To guide you through the process, Linksys strongly

recommends that you run the Setup Wizard on the Setup CD-ROM. If you prefer to manually set up the Router, use

the instructions in the Quick Installation or this User Guide to help you. These instructions should be all you need

to get the most out of the Wireless-G Broadband Router.

Chapter 2: Planning Your Wireless Network

Network Topology

Wireless-G Broadband Router with 2 Phone Ports

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 or wireless router, such as the

Wireless-G Broadband Router with 2 Phone Ports, which serves as the main point of communications in a

wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam

within a certain radial range of the Router.

You can arrange the Router and multiple access points to work in

succession to extend the roaming range, and you can set up your wireless network 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 a wireless router or

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.

Network Layout

The Wireless-G Broadband Router with 2 Phone Ports has been specifically designed for use with both your

802.11b and 802.11g products. Now, products using these standards can communicate with each other.
