Chapter 1: Introduction  
Welcome  
network: a series of computers or devices  
connected for the purpose of data sharing, storage,  
and/or transmission between users.  
Thank you for choosing the Compact Wireless-G USB Network Adapter with SpeedBooster. With this Adapter, your  
wireless networking experience will be faster and easier than ever.  
How does the Adapter do this? Like all wireless products, the Adapter allows for greater range and mobility  
within your wireless network. Connecting to your PC via the USB port means that this Adapter leaves the PC’s  
slots open for other purposes. This adapter communicates over the 802.11g wireless standard, one of the newest  
wireless standards, to communicate with your network.  
adapter: a device that adds network functionality to your PC.  
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.  
But what does all of this mean?  
Networks are useful tools for sharing computer resources. 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 are not only useful in homes and offices, they can also be fun.  
PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the  
same wireless settings, within their transmission radius, they form a wireless network.  
And now, with SecureEasySetup, setting up your network and your Compact Wireless-G USB Network Adapter is  
easier than ever.  
Use the instructions in this Guide to help you connect the Adapter, set it up, and configure it for your network.  
These instructions should be all you need to get the most out of the Adapter.

Chapter 2: Planning your Wireless Network  
Network Topology  
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.  
ad-hoc: a group of wireless devices  
communicating directly with each other (peer-  
to-peer) without the use of an access point  
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.  
access point: device that allows wireless-  
equipped computers and other devices to  
communicate with a wired network.  
infrastructure: Configuration in which a  
wireless network 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.  
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.

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.  
802.11b: an IEEE wireless networking standard  
that specifies a maximum data transfer rate of  
11Mbps and an operating frequency of 2.4GHz.  
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: device that is the central point of connection for  
computers and other devices in a network, so data can  
be shared at full transmission speeds.  
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.  
router: a networking device that connects multiple networks  
together, such as a local network and the Internet.

Compact Wireless-G USB Network Adapter with SpeedBooster  
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 PC 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

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?  
The Adapter 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, the Adapter 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 64-bit or 128-bit shared key algorithm, as  
described in the IEEE 802.11 standard.

Appendix C: 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 C: Wireless Security  
Security Precautions  
34  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
Compact Wireless-G USB Network Adapter with SpeedBooster  
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. Four modes  
are available: WPA-Personal, WPA2-Personal, WPA-Enterprise, and RADIUS. WPA-Personal 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 Standard), which utilizes a symmetric 128-Bit block data encryption. WPA2-Personal  
only uses AES encryption, which is stronger than TKIP. WPA-Enterprise offers two encryption methods, TKIP  
and AES, with dynamic encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a  
RADIUS server for authentication.  
Appendix C: Wireless Security

WPA-Personal. If you do not have a RADIUS server, select the type of algorithm you want to use, TKIP or AES,  
and enter a password in the Passphrase field of 8-63 characters.  
WPA2-Personal. Enter a password in the Passphrase field of 8-63 characters.  
WPA-Enterprise. 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-Enterprise offers two encryption methods, TKIP and  
AES, with dynamic encryption keys. Enter the RADIUS server’s IP Address and port number, along with a key  
shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device  
how often it should change the 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.) First, enter the RADIUS server’s IP Address and port number, along  
with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption,  
and either generate a WEP key through the Passphrase or enter the WEP key manually.  
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.
