Ad-Hoc and Infrastructure Modes

Planning Your Wireless Network

Planning Your Wireless Network

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 computers

with wireless capabilities 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

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 PTZ Internet Camera is compatible with all 802.11g routers, such as model number

WRVS4400N, as well as access points, including model number WAP4400N. The camera can

also communicate with network adapters, such as the Wireless-G Notebook Adapter (model

number WPC4400N) for your laptop computers, Wireless-G PCI Adapter (model numbers

WMP200) for your desktop PCs, and Wireless-G USB Adapter (model number WUSB200) for

your computers 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

for more information about products that

work with the PTZ Internet Camera.

Wireless Security

Planning Your Wireless Network

Wireless Security

Linksys wants to make wireless networking as safe and easy for you as possible. The current

generation of Linksys products provide several network security features, but they require

specific action on your part for implementation. So, keep the following in mind whenever you

are setting up or using your wireless network.

Security Precautions

The following is a complete list of security precautions to take (at least steps 1 through 5 should

be followed):

1.

Change the default SSID.

2.

Disable SSID Broadcast.

3.

Change the default password for the Administrator account.

4.

Change the SSID periodically.

5.

Use the highest encryption algorithm possible. Use WPA if it is available. Please note that

this may reduce your network performance.

6.

Change the WEP encryption keys periodically.

Security Threats Facing Wireless Networks

Wireless networks are easy to find. Hackers know that in order to join a wireless network,

wireless networking products first listen for “beacon messages”. These messages can be easily

decrypted and contain much of the network’s information, such as the network’s SSID (Service

Set Identifier). Here are the steps you can take:

Change the administrator’s password regularly.

With every wireless networking device you

use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your

network administrator is the only person who can change network settings. If a hacker gets a

hold of the administrator’s password, he, too, can change those settings. So, make it harder for a

hacker to get that information. Change the administrator’s password regularly.

SSID.

There are several things to keep in mind about the SSID:

•

Disable Broadcast

•

Make it unique

•

Change it often

NOTE:

Some of these security features are available only

through the network router or access point. Refer to the

router or access point’s documentation for more

information.

Security Threats Facing Wireless Networks

Planning Your Wireless Network

Most wireless networking devices will give you the option of broadcasting the SSID. While this

option may be more convenient, it allows anyone to log into your wireless network. This

includes hackers. So, don’t broadcast the SSID.

Wireless networking products come with a default SSID set by the factory. (The Linksys default

SSID is “linksys”.) Hackers know these defaults and can check these against your network.

Change your SSID to something unique and not something related to your company or the

networking products you use.

Change your SSID regularly so that any hackers who have gained access to your wireless

network will have to start from the beginning in trying to break in.

MAC Addresses.

Enable MAC Address filtering. MAC Address filtering will allow you to provide

access to only those wireless nodes with certain MAC Addresses. This makes it harder for a

hacker to access your network with a random MAC Address.

WEP Encryption.

Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless

security concerns. This is overstating WEP’s ability. Again, this can only provide enough security

to make a hacker’s job more difficult.

There are several ways that WEP can be maximized:

•

Use the highest level of encryption possible

•

Use “Shared Key” authentication

•

Change your WEP key regularly

WPA/WPA2 Personal.

Wi-Fi Protected Access (WPA) This method offers two encryption

methods, TKIP and AES, with dynamic encryption keys.

A network encrypted with WPA/WPA2 is more secure than a network encrypted with WEP,

because WPA/WPA2 uses dynamic key encryption. To protect the information as it passes over

the airwaves, you should enable the highest level.

Implementing encryption may have a negative impact on your network’s performance, but if

you are transmitting sensitive data over your network, encryption should be used.

These security recommendations should help keep your mind at ease while you are enjoying

the most flexible and convenient technology Linksys has to offer.

CAUTION:

Always remember that each device in your

wireless network MUST use the same encryption method

and encryption key or your wireless network will not

function properly.
