Wireless-G Access Point with Power Over Ethernet

Chapter 1: Introduction

Welcome

Thank you for choosing the Wireless-G Access Point with Power Over Ethernet. 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 can support communications on up to eight wireless
networks, using Virtual Local Area Network (VLAN) technology.

The Wireless-G Access Point with Power Over Ethernet also offers the convenience of Power over Ethernet (PoE)
capability, so it can receive data and power over a single Ethernet network cable.

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.

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

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 with Power Over Ethernet, 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

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.

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 using the roaming capabilities, choose a feasible radio channel and optimum access point position. Proper
access point positioning combined with a clear radio signal will greatly enhance performance.

roaming: the ability to take a wireless device from one
access point's range to another without losing the
connection.

Network Layout

The Wireless-G Access Point with Power Over Ethernet has been designed for use with 802.11g and 802.11b
products. The Access Point is compatible with 802.11g and 802.11b adapters, such as the Notebook Adapters for
your laptop computers, PCI Adapters for your desktop PCs, and USB Adapters for when you want to enjoy USB
connectivity. These wireless products can also communicate with a 802.11g or 802.11b Wireless PrintServer.

To link your wired network with your wireless network, connect the Access Point’s Ethernet network port to any
switch or router. If you want to use Power Over Ethernet (POE), then connect the Access Point to any switch or
router that complies with the POE standard (802.3af)—or you can use a POE injector, such as the Linksys
WAPPOE or WAPPOE12.

With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at

The Wireless - Advanced Wireless Settings Tab

This screen allows you to configure the advanced settings for the Access Point. In most cases, these settings do
not need to be changed.

Advanced Wireless

You can change the data transmission and output power settings for the Access Point.

CTS Protection Mode. The CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to
catch all Wireless-G 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 Enabled if you want to permanently enable this
feature, or select Disabled if you want to permanently disable this feature.

Wireless Isolation. When this feature is enabled, PCs using different SSIDs cannot see each other, so the
different wireless networks are kept separate from each other. In most cases, including wireless hotspots, keep
the default, Enabled. If you want PCs from different wireless networks to communicate, select Disabled.

Basic Data Rates. This setting is not actually one rate of transmission but a series of rates that are advertised to
the other wireless devices in your network, so they know at which 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 are 1-2Mbps, for use with older wireless technology, and All, when you wish to have all rates
advertised. The Basic Data Rates are not the rates transmitted; the rates transmitted can be configured through
the TX Rate setting on the Wireless - Basic Wireless Settings tab.

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).

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 power­saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with
wireless transmissions.

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. Should 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 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.

Output Power. You can adjust the output power of the Access Point to get the appropriate coverage for your
wireless network. Select the level you need for your environment. If you are not sure which setting to choose,
then keep the default setting, 100%.

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 user guide 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 user
guide 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?

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 to communicate continuously while its user is moving freely
throughout an area greater than that covered by a single Access Point. Before using the roaming function, the
user must make sure that the computer 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.

Frequently Asked Questions

Wireless-G Access Point with Power Over Ethernet

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.

Frequently Asked Questions

38

Wireless-G Access Point with Power Over Ethernet

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 65, 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

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.

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.

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.

Appendix B: Wireless Security
Security Precautions

40

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.

Appendix B: Wireless Security
Security Threats Facing Wireless Networks

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.

41

Wireless-G Access Point with Power Over Ethernet

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.
