Welcome
Wireless-G Access Point
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Access Point. This Access Point will allow you to network wirelessly better
than ever.
How does the Access Point do all of this? An access point allows for greater range and mobility within your
wireless network while also allowing you to connect the wireless network to a wired environment. Being a dual-
band access point, not only does the Access Point bring you these benefits, it also allows two wireless standards,
802.11g and 802.11b, to communicate with each other. This means that PCs with different wireless standards
can communicate with each other and with a wired network.
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 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 and 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 Wired Local Area Network. The Access Point bridges wireless networks of both 802.11g and 802.11b
standards and wired networks.
Use the instructions in this Guide to help you connect the Access Point, set it up, and configure it to bridge your
different networks. These instructions should be all you need to get the most out of the Access Point.
802.11b: a wireless networking standard that specifies
a maximum data transfer rate of 11Mbps and an
operating frequency of 2.4GHz.
802.11g: a 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.
adapter: a device that adds network functionality to your PC
ethernet: network protocol that specifies how data is placed
on and retrieved from a common transmission medium
lan (local area network): the computers and networking
products that make up your local network
network: a series of computers or devices
connected together

Network Topology
Wireless-G Access Point
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.
Linksys wireless adapters also provide users access to a wired network when using an access point, such as the
Wireless-G 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.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may 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 may be doubled.
Roaming
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.
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.
infrastructure: a wireless network
that is bridged to a wired network via
an access point.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-
to-peer) without the use of an access point.
roaming: the ability to take a wireless device
from one access point's range to another
without losing the connection.
ssid: your wireless network's name

Securing or Unprotecting your Wireless Guard Network
There may be some instances where you would want to completely unprotect your network connection so it is
not using the Wireless Guard security. For example, if you take your laptop to another location to give a
presentation, and connect to a network that is running 802.1x security, the Linksys Wireless Guard software on
your laptop will prevent you from logging in to another network. You will need to manually unprotect your
network connection so you can log in. When you come back to your own network, you won't have to manually re-
secure the network connection. Linksys Wireless Guard will recognize it and automatically reinstate security.
To unprotect a network
Right-click on the green Wireless Guard Network key icon on the right-side of the system tray at the bottom of
your screen. Select Unprotect this Network Connection from the menu.
When the screen asks if you're sure you want to unprotect the network, click Yes.
To secure an unprotected network
Right-click on the green Wireless Guard Network key icon. Select Secure this Network Connection from the
menu.
When the screen asks if you're sure you want to secure the network. Click Yes.

The Wireless Security settings configure the security of your wireless network. There are four wireless security
mode options supported by the Access Point: WPA Pre-Shared Key, WPA RADIUS, RADIUS, and WEP. (WPA stands
for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired
Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These four are briefly
discussed here. For detailed instructions on configuring wireless security for the Access Point, turn to “Appendix
B: Wireless Security.”
WPA Pre-Shared Key. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys.
Select the type of algorithm, TKIP or AES. Enter a WPA Shared Key of 8-32 characters. Then enter a Group Key
Renewal period, which instructs the Access Point how often it should change the encryption keys.
WPA RADIUS. This option features WPA used in coordination with a RADIUS server. (This should only be used
when a RADIUS server is connected to the Access Point.) First, select the type of WPA algorithm you want to use,
TKIP or AES. Enter the RADIUS server’s IP Address and port number, along with a key shared between the Access
Point and the server. Last, enter a Key Renewal Timeout, which instructs the Access Point how often it should
change the encryption keys.
If you want to get the security of WPA RADIUS, but without having to build your own RADIUS network, Linksys
offers Linksys Wireless Guard, a subscription service. For more information, click CLICK HERE.

LAN MAC Address
The Access Point offers five modes of operation: Access Point, AP (Access Point) Client, Wireless Repeater, and
Wireless Bridge. For the bridging mode and Repeater mode, make sure the channel, SSID, and WEP keys are the
same.
Access Point - The Operational Mode is set to Access Point by default. This connects your wireless PCs to a
wired network. In most cases, no change is necessary.
AP (Access Point) Client - When set to Access Point Client mode, the Access Point Client is able to talk to one
remote access point within its range. This mode allows the Access Point Client to act as a client of a remote
access point. The Access Point Client cannot communicate directly with any wireless clients. A separate network
attached to the Access Point Client can then be wirelessly bridged to the remote access point. Enter the required
LAN MAC address of the remote access point in the Remote AP MAC Address field.
To select an available access point, click the Site Survey button and choose from the access points listed by
clicking on the radio button for the appropriate access point and clicking the close button. If you do not see an
access point listed, click the Refresh button and another survey will be performed.
IMPORTANT: For all modes of operation EXCEPT

Before making any changes to the Wireless tab, please check your wireless settings on other systems, as these
changes will alter the effectiveness of the Access Point. In most cases, these settings do not need to be changed.
Authentication Type. 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.
Transmission Rates. The default setting is Auto. The range is from 1 to 54Mbps. The rate of data transmission
should be set depending on the speed of your wireless network. You can select from a range of transmission
speeds, or you can keep the default setting, Auto, to have the Access Point automatically use the fastest possible
data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed
between the Access Point and a wireless client.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having
severe problems with your Wireless-G products not being able to transmit to the Access Point in an environment
with heavy 802.11b traffic. This function boosts the Access Point’s ability to catch all Wireless-G transmissions
but will severely decrease performance.
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates, advertising to the
other wireless devices in your network at what rates the Access Point can transmit. At the Default setting, the
Access Point will advertise that it will automatically select the best rate for transmission. Other options of rates to
advertise are 1-2Mbps, for use with older wireless technology, and All, when you wish to make all rates
advertised. The Basic Rate is not the rate transmitted; that is the Transmission Rate.
Antenna Selection. This selection is for choosing which antenna transmits data, left or right. By default, the
Diversity antenna selection, used to increase reception, is chosen.
Frame Burst. Enabling this option should provide your network with greater performance, depending on the
manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Off.
Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by
the Access Point to keep the network synchronized. A beacon includes the wireless LAN service area, the AP
address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic
Indicator Message (TIM).
RTS Threshold. This setting determines how large a packet can be before the Access Point coordinates
transmission and reception to ensure efficient communication. This value should remain at its default setting of
2,346. Should you encounter inconsistent data flow, only minor modifications are recommended.

Fragmentation Length. This specifies the maximum size a data packet will be before splitting and creating a
new packet and should remain at its default setting of 2,346. A smaller setting means smaller packets, which
will create more packets for each transmission. If you have decreased this value and experience high packet
error rates, you can increase it again, but it will likely decrease overall network performance. Only minor
modifications of this value are recommended.
DTIM Interval. This value indicates how often the Access Point sends out a Delivery Traffic Indication Message.
Lower settings result in more efficient networking, while preventing your PC from dropping into power-saving
sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with wireless

The product supports the following IEEE 802.11 functions:
•CSMA/CA plus Acknowledge protocol
•Multi-Channel Roaming
•Automatic Rate Selection
•RTS/CTS feature
•Fragmentation
•Power Management
What is Ad-hoc?
An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent
wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to
enterprise scale for wireless access to a central database, or wireless application for mobile workers.
47
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G 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 as the Access Point of the 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).
48
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Access Point
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, the WLAN
series offers the encryption function (WEP) to enhance security and access control. Users can set it up
depending upon their needs.
Can Linksys Wireless products support file and printer sharing?
Linksys Wireless products perform the same function as LAN products. Therefore, Linksys Wireless products
can work with Netware, Windows NT/2000, or other LAN operating systems to support printer or file sharing.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40-bit shared-key algorithm, as
described in the IEEE 802.11 standard.
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter, that allows the network to identify it at the hardware level.
For all practical purposes, this number is usually permanent. Unlike IP addresses, which can change every
time a computer logs on to the network, the MAC address of a device stays the same, making it a valuable
identifier for the network.
How do I avoid interference?
Using multiple Access Points on the same channel and in close proximity to one another will generate
interference. When employing multiple Access Points, be sure to operate each one on a different channel
(frequency).
How do I reset the Access Point?
Press the Reset button on the back of the Access Point for about ten seconds. This will reset the unit to its
default settings.
49
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Access Point
How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every obstacle placed
between an Access Point and wireless PC will create signal loss. Leaded glass, metal, concrete floors, water
and walls will inhibit the signal and reduce range. Start with your Access Point and your wireless PC in the
same room and move it away in small increments to determine the maximum range in your environment.
You may also try using different channels, as this may eliminate interference affecting only one channel.
Also, due to FCC regulations, more power may be transmitted, using 802.11a, on channels 52, 56, 60 and 64,
than on the lower channels. Lastly, check the Advanced tab of the Web-Based Utility and make sure that
FULL is selected in the Transmission Rate field.
Does the Access Point function as a firewall?
No. The Access Point is only a bridge from wired Ethernet to wireless clients.
I have excellent signal strength, but I cannot see my network.
WEP is probably enabled on the Access Point, but not on your wireless adapter (or vice versa). Verify that the
same WEP Keys and levels (64 or 128) are being used on all nodes on your wireless network.
What is the maximum number of users the Access Point facilitates?
No more than 65, but this depends on the volume of data and may be less if many users create a large
amount of network traffic.
How many channels/frequencies are available with the Access Point?
Using 802.11b or draft 802.11g, there are eleven available channels, ranging from 1 to 11.

Appendix B: Wireless Security
Security Precautions
Dual-Band Wireless Access Point
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 (as shown in this User Guide) (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.
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.
To ensure network security, steps one through five should be followed, at least.
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.
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.
51
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Dual-Band Wireless Access Point
SSID. There are several things to keep in mind about the SSID:
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
3. Change your WEP key regularly
WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are
available: Pre-Shared Key and RADIUS. Pre-Shared Key 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. RADIUS (Remote Authentication Dial-In User Service) utilizes a
RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP.
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.
52
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Dual-Band Wireless Access Point
WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a
password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time
between 0 and 99,999 seconds, which instructs the Router or other device how often it should change the
encryption keys.
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.) First, select the type of WPA algorithm, TKIP or AES. 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.
