Chapter 2: Planning your Wireless Network
Network Topology
topology: the physical layout of a network.
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or
adapters can communicate with one another to form an ad-hoc network.
access point: a device that allows wireless-equipped
computers and other devices to communicate with a wired
network. Also used to expand the range of a wireless network
Linksys wireless adapters also provide users access to a wired network when using an access point or wireless
router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an
infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless
router.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-
to-peer) without the use of an access point.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the
effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an infrastructure network can be doubled.
router: a networking device that
connects multiple networks together.
Roaming
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same channel and SSID.
ssid: your wireless network's name.
Before enabling you consider roaming, choose a feasible radio channel and optimum access point position.
Proper access point positioning combined with a clear radio signal will greatly enhance performance.

802.11a: a wireless networking standard that
specifies a maximum data transfer rate of
54Mbps and an operating frequency of 5GHz.
Linksys wireless access points and wireless routers have been designed for use with 802.11a, 802.11b, and
802.11g products. With 802.11g products communicating with the 802.11b standard and some products
incorporating both “a” and “g”, products using these standards can communicate with each other.
Access points and wireless routers are compatible with 802.11a, 802.11b and 802.11g adapters, such at the PC
Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB
connectivity. Wireless products will also communicate with the wireless PrintServer.
switch: a data switch that connects computing
devices to host computers, allowing a large number of
devices to share a limited number of ports
When you wish to connect your wired network with your wireless network, network ports on access points and
wireless routers can be connected to any of Linksys's switches or routers.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at

Key, which is a security standard stronger than WEP encryption, and RADIUS stands for Remote
Authentication Dial-In User Service. If you don’t want to use encryption, select Disabled. Then, click Next to
continue or Back to return to the previous screen.
WEP
Security - To use WEP encryption, select 64-bits or 128-bit characters from the drop-down menu, and enter
a passphrase or key.
Passphrase - Instead of manually entering a WEP key, you can enter a passphrase in the Passphrase field, so
a WEP key is automatically generated. It is case-sensitive and should not be longer than 16 alphanumeric
characters. This passphrase must match the passphrase of your other wireless network devices and is
compatible with Linksys wireless products only. (If you have any non-Linksys wireless products, enter the
WEP key manually on those products.)
Figure 6-13: Wireless Security for New Profile
Transmit Key - The default transmit key number is 1. If your network’s access point or wireless router uses
transmit key number 2, 3, or 4, select the appropriate number from the Transmit Key drop-down box.
passphrase: used much like a password, a passphrase
simplifies the WEP encryption process by automatically
generating the WEP encryption keys for Linksys products
Key 1- The WEP key you enter must match the WEP key of your wireless network. If you are using 64-bit WEP
encryption, then the key must consist of exactly 10 hexadecimal characters. If you are using 128-bit WEP
encryption, then the key must consist of exactly 26 hexadecimal characters. Valid hexadecimal characters
are “0” to “9” and “A” to “F”.
Authentication -The default is set to Auto, where it auto-detects for Shared Key or Open system. Shared
Key is when both the sender and the recipient share a WEP key for authentication. Open key is when the
sender and the recipient do not share a WEP key for authentication. All points on your network must use the
same authentication type.

Frequently Asked Questions

Wireless-G Notebook Adapter
What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to
communicate directly with each other. The ad-hoc wireless network will not communicate with any wired
network.
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a
wired network through a wireless access point.
What is roaming?
Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout
an area greater than that covered by a single access point. Before using the roaming function, the workstation
must make sure that it is the same channel number with the access point of dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each
node and access point, for example, must always acknowledge receipt of each message. Each node must
maintain contact with the wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a
system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates
such factors as signal strength and quality, as well as the message load currently being carried by each access
point and the distance of each access point to the wired backbone. Based on that information, the node next
selects the right access point and registers its address. Communications between end node and host computer
can then be transmitted up and down the backbone.
As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in
touch with the original access point or whether it should seek a new one. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in
the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in
reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for
reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that
Appendix A: Troubleshooting

Wireless-G Notebook Adapter
the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to
the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that
is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical
channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence Spread-
Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if
one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low
power wideband noise and is rejected (ignored) by most narrowband receivers.
Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum
technology, it has the inherent security feature of scrambling. On the software side, WLAN offers the encryption
function (WEP) to enhance security and access control.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
802.11 standard.

Appendix B: 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. Enable MAC Address Filtering.
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.
5. Change the SSID periodically.
6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
your network performance.
7. 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:
Appendix B: Wireless Security
Security Precautions
32
Download from Www.Somanuals.com. All Manuals Search And Download.
Wireless-G Notebook Adapter
1. Disable Broadcast
2. Make it unique
3. Change it often
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:
1. Use the highest level of encryption possible
2. Use “Shared Key” authentication
Important: 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.
3. Change your WEP key regularly
WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Three modes are
available: WPA-PSK, WPA Radius, and Radius. WPA-PSK gives you a choice of two encryption methods: TKIP
(Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message
Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes
a symmetric 128-Bit block data encryption. WPA RADIUS offers two encryption methods, TKIP and AES, with
dynamic encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for
authentication.

WPA-PSK. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, and enter a
password in the Passphrase field of 8-63 characters.
WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
server is connected to the Router or other device.) WPA Radius offers two encryption methods, TKIP and AES,
with dynamic encryption keys.
RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
connected to the Router or other device.)
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.
