Chapter 2: Planning Your Wireless Network

Introduction

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 and other devices, such as

peripherals, in a WLAN share the same frequency channel and SSID, which is an identification name for wireless

devices.

Ad-Hoc and Infrastructure Modes

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 accessed 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. (A wireless router can also be used because a wireless router

incorporates the capabilities of an access point.) 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 (wired) 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.

Network Layout

The Wireless-B Internet Video Camera is compatible with all 802.11b and 802.11g routers, such as model

numbers BEFW11S4 and WRT54G, as well as access points, including model numbers WAP11 and WAP54G. The

Infrastructure:

configuration in which

a wireless network is bridged to a

wired network via an access point.

LAN (Local Area Network):

the

computers and networking products

that make up the network in your home

or office.

Ad-hoc:

a group of wireless devices

communicating directly to each other

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

access point.

Wireless-B Internet Video Camera

Camera will also communicate with network adapters, such as the Wireless-B and Wireless-G Network Adapters

(model numbers WPC11 and WPC54G) for your laptop computers, Wireless-B and Wireless-G PCI Adapters (model

numbers WMP11 and WMP54G) for your desktop PCs, and Wireless-B USB Adapter (model number WUSB11) for

your computer when you want to enjoy USB connectivity.

With these, and many other Linksys products, your networking options are limitless. Go to the Linksys website at

Camera

Camera LEDs

The Camera has four LEDs to let you know how the Camera is functioning.

Ready

Green. The

Ready

LED lights up when the Camera is powered on. It flashes while the Camera

is initializing and is steadily lit when the Camera is ready for use.

Act/Link

Green. The

Act/Link

LED flashes when there is activity.

LAN

Green. The

LAN

LED lights up when there is a connection to a wired network. It flashes when

data is transmitted to or received from the wired network.

Wireless

Green. The

Wireless

LED lights up when there is a connection to a wireless network. It flashes

when data is transmitted to or received from the wireless network.

Camera Head

The Camera head and its focus ring allow you to modify the aim and focus of the Camera.

To alter the Camera’s aim, swivel the Camera head.

To adjust the Camera’s focus, rotate the dark gray focus ring.

Chapter 4: Connecting the Wireless-B Internet Video Camera

for Setup

Overview

Before you set up the Camera, connect it to a wired or wireless network. Proceed to the appropriate section for

your setup.

If you need to move the Camera from a wired network to a wireless network, or vice versa, go to this section,

“Moving the Camera to a Different Network.”

Connection to a Wired Network for Setup

1.

Connect the Ethernet network cable to your router or switch. If you want to connect the Camera directly to

your PC, use a crossover Ethernet network cable (not included).

2.

Connect the other end of the cable to the LAN port on the Camera. See Figure 4-1.

3.

Connect the power adapter to the Power port on the Camera.

4.

Plug the power adapter into an electrical outlet.

The Camera’s Ready LED flashes while the Camera is initializing. The Camera is ready for use when the Ready

and LAN LEDs are solidly lit.

Proceed to “Chapter 5: Setting up and Mounting the Wireless-B Internet Video Camera.”

Connection to a Wireless Ad-Hoc Network for Setup

1.

Make sure your computer has the following wireless settings:

•

SSID - linksys

•

Network Mode - Ad-Hoc

•

Channel - 6

•

WEP - Disabled

2.

Connect the power adapter to the Power port on the Camera.

NOTE:

You MUST connect the Camera to a PC,

router, or switch using the Ethernet network

cable BEFORE powering on the Camera.

Otherwise, the Camera will not function.
