Welcome
Wireless-G Access Point with Power Over Ethernet and Rangebooster
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Access Point with Power Over Ethernet and Rangebooster. 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. In fact, the
Wireless-G Access Point with Power Over Ethernet and Rangebooster can support communications on up to four
wireless networks, using Virtual Local Area Network (VLAN) technology.
The Wireless-G Access Point with Power Over Ethernet and Rangebooster also offers the convenience of Power
over Ethernet (PoE) capability, so it can receive data and power over a single Ethernet network cable. You can
even connect wired networks in two different buildings, by using two Access Points set to Wireless Bridge mode.
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 client cards or 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 Wireless 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 defined in IEEE 802.3 standard
that specifies how data is placed on and retrieved from a
common transmission medium.
lan (local area network): the computers and networking
devices that make up your local network.
network: a series of computers or devices connected
together.
poe (power over ethernet): a technology enabling an
Ethernet network cable to deliver both data and power.
access point: a device that allows wireless-equipped
computers and other devices to communicate with each
other and with devices on a wired network. Also used to
expand the range of a wireless network.

Chapter 2: Planning Your Wireless Network
Network Topology
Wireless-G Access Point with Power Over Ethernet and Rangebooster
Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one or more wireless adapters. Computers in a
wireless network must be configured to share the same radio channel to talk to each other. Several PCs equipped
with wireless cards or adapters can communicate with each other to form an ad-hoc network without the use of
an access point.
Linksys also provides products to allow wireless adaptors to access wired network through a bridge such as the
wireless 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 or wireless network
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 more than doubled since
Access Point can transmit signal at higher power to the wireless space.
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 wireless network (SSID), wireless channel, and wireless security settings.
This Access Point has 802.11F Inter-Access Point Protocol (IAPP) to complete the roaming process in seconds. If
your wireless networks share the same IP subnet, this will not disrupt your data connection while moving around.
Before 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

The Wireless - Advanced Wireless Settings Tab
This screen allows you to configure the advanced settings for the Access Point. Linksys recommends to let your
Access Point automatically adjust the parameters for maximum data throughput.
Advanced Settings
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to catch
all wireless transmissions, but will severely decrease performance. Keep the default setting, Auto, so the Access
Point can use this feature as needed, when the Wireless-G products are not able to transmit to the Access Point
in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature.
BSSBasicRateSet. This setting is a series of rates that are advertised to other wireless devices as defined in
IEEE 802.11 specifications, so they know which data rates the Access Point can support. One of the rates is
picked from the list for transmitting control frames, broadcast/multicast frames, or ACK frames. To support both
802.11b & 802.11g devices, use the Default (Mixed mode) setting so that frames can be decoded by all devices.
To support 802.11g devices only, use the All (G-only mode) setting to achieve higher frame rates. For regular data
frames, the transmission rate is configured through the Tx Rate Limiting on the Wireless - VLAN & QoS tab.
Power Output.
Select the level you need for your environment. If you are not sure of which setting to choose,
then keep the default setting, 100%.
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 networks service area, the
Access Point address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and
the Traffic Indicator Message (TIM). The default is 100 ms.
DTIM Interval. This value indicates how often the Access Point sends out a Delivery Traffic Indication Message
(DTIM). 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 transmissions. The default is 1 ms.
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
2347. If you encounter inconsistent data flow, only minor modifications are recommended.

Fragmentation Threshold. This specifies the maximum size a data packet can be before splitting and creating a
new packet. It should remain at its default setting of 2346. A smaller setting means smaller packets, which will
create more packets for each transmission. If you experience high packet error rates, you can decrease this
value, but it will likely decrease overall network performance. Only minor modifications of this value are
recommended.

VLAN ID. Select a number between 1 and 4094 to identify the VLAN. Multiple SSIDs can share the same VLAN
value.
Priority. You can assign the default priority (802.1p COS bits) for packets coming in from each wireless network
by selecting a number from the drop-down menu. The higher the number, the higher the priority will be. The
default is 0.
Tx Rate Limiting. You can limit the maximum data rate used in your network to save bandwidth and power
consumption on client devices. The actual data rate is determined by the Auto-Fallback mechanism between your
Access Point and a client device. The default is 54 Mbps for Mixed or G-Only wireless mode, 11 Mbps for B-Only
mode.
WMM. Wi-Fi Multimedia is a QoS feature defined by the WiFi Alliance before IEEE 802.11e was finalized. Now it is
part of IEEE 802.11e. When this is enabled, it provides four priority queues for different types of traffic. It
automatically maps the incoming packets to the appropriate queues based on QoS settings (in the IP or layer 2
header). WMM provides the capability to prioritize wireless traffic in your environment. The default is Disabled
(unchecked).
The AP Mode Tab
On this screen you can change the Access Point’s mode of operation. In most cases, you can keep the default

Frequently Asked Questions
Wireless-G Access Point with Power Over Ethernet and Rangebooster
Appendix A: Troubleshooting
This appendix provides solutions to problems that may occur during the installation and operation of the
Wireless-G Access Point with Power Over Ethernet. Read the descriptions below to help solve your problems. If
you can't find an answer here, check the Linksys website at www.linksys.com.
Frequently Asked Questions
Can the Access Point act as my DHCP Server?
No. The Access Point is nothing more than a wireless hub, and as such cannot be configured to handle DHCP
capabilities.
Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a network. Consult the
application’s documentation to determine if it supports operation over a network.
Can I play multiplayer games with other users of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game’s
documentation for more information.
What is the IEEE 802.11b standard?
It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware
from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard.
The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
What is the IEEE 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware
from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard.

Frequently Asked Questions
Wireless-G Access Point with Power Over Ethernet and Rangebooster
What IEEE 802.11g features are supported?
The product supports the following IEEE 802.11g functions:
• CSMA/CA plus Acknowledge protocol
• OFDM 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.
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 set to 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.

Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Access Point with Power Over Ethernet and Rangebooster
What is the 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?
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 a
variety of wireless security methods 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.
43
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Access Point with Power Over Ethernet and Rangebooster
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, make 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.
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,
open the Access Point’s Web-based Utility. Click the Wireless tab and then the Advanced Wireless tab. Make
sure the Output Power is set to 100%.
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.
Wireless security, such as WEP or WPA, is probably enabled on the Access Point, but not on your wireless adapter
(or vice versa). Verify that the same wireless security settings are being used on all devices in your wireless
network.
What is the maximum number of users the Access Point can handle?
No more than 63, but this depends on the volume of data and may be fewer if many users create a large amount
of network traffic.

Appendix B: Wireless Security
Security Precautions
Wireless-G Access Point with Power Over Ethernet and Rangebooster
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.
45
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Wireless-G Access Point with Power Over Ethernet and Rangebooster
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. Change your WEP key regularly
WPA. Wi-Fi Protected Access (WPA) is the replacement standard for WEP in Wi-Fi security. Two modes are
available: Personal, and Enterprise. Both give 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. Enterprise 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.
46
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Wireless-G Access Point with Power Over Ethernet and Rangebooster
WPA Personal. 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 8-63 characters, and enter a Group Key Renewal period time between
0 and 99,999 seconds, which instructs the AP or other device how often it should change the encryption keys.
WPA Enterprise. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
server is connected to the AP 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.
WPA2. Wi-Fi Protected Access 2 (WPA2) is the latest security standard in Wi-Fi security. Two modes are available:
Personal and Enterprise. WPA2 always uses AES (Advanced Encryption System) for stronger data encryption.
WPA2 Personal. If you do not have a RADIUS server, enter a password in the Pre-Shared key field of 8-63
characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the
AP or other device how often it should change the encryption keys.
WPA2 Enterprise. WPA2 used in coordination with a RADIUS server. (This should only be used when a
RADIUS server is connected to the AP 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, enter a Group Key Renewal period,
which instructs the device how often it should change the encryption keys.
WPA2 Mixed. WPA2 Mixed modes provide users an upgrade path from WPA to WPA2. You can have client devices
running both WPA and WPA2 and the Access Point will automatically select the security method used by the
client.
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.
