Indoors, computers can connect over 802.11 wireless networks at a maximum range of 500 feet (152.4 m)
for 802.11b devices. However, the operating distance or range of your wireless connection can vary
significantly, based on the physical placement of the wireless access point.

For best results, identify a location for your wireless access point according to these guidelines:

• Away from potential sources of interference , such as PCs, large metal surfaces, microwaves, and 2.4 GHz cordless
phones.

• In an elevated location such as a high shelf that is near the center of the wireless coverage area for all mobile
devices.

Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly
connect to the wireless access point.

Chapter 2

Introduction

This chapter introduces the NETGEAR WG302 802.11g ProSafe Wireless Access Point. Minimal
prerequisites for installation are presented in “System Requirements” on page 2-4.

About the WG302 802.11g ProSafe Wireless Access Point

The WG302 802.11g ProSafe W ireless Access Point is the basic building block of a wireless LAN
infrastructure. It provides connectivity between Ethernet wired networks and radio-equipped
wireless notebook systems, desktop systems, print servers, and other devices.

The WG302 provides wireless connectivity to multiple wireless network devices within a fixed
range or area of coverage, interacting with a wireless network interface card (NIC) via an antenna.
T ypically, an individual in-building access point provides a maximum connectivity area with about
a 300 foot radius. The WG302 802.11g ProSafe Wireless Access Point can support a small group
of users in a range of several hundred feet. Most access points are rated between 30-70 users
simultaneously.

The WG302 802.11g ProSafe Wi reless Access Point acts as a bridge between the wired LAN and
wireless clients. Connecting multiple WG302 Access Points via a wired Ethernet backbone can
further lengthen the wireless network coverage. As a mobile computing device moves out of the
range of one access point, it moves into the range of another. As a result, wireless clients can freely
roam from one Access Point to another and still maintain seamless connection to the network.

The auto-sensing capability of the WG302 802.11g ProSafe Wireless Access Point allows packet
transmission at up to 108 Mbps, or at reduced speeds to compensate for distance or
electromagnetic noise interference.

Introduction 2-1

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Key Features

The WG302 Access Point is easy-to-use and provides solid wireless and networking support.

Supported Standards and Conventions

The following standards and conventions are supported:

• Standards Compliant. The Wireless Access Point complies with the IEEE 802.11g for

Wireless LANs.

• WEP support. Support for WEP is included. Both 64-bit, 128-bit, and 152-bit keys are

supported.

• DHCP Client Support. DHCP provides a dynamic IP address to PCs and other devices upon

request. The WG302 can act as a client and obtain information from your DHPC server.

• SNMP Support. Support for Simple Network Management Protocol (SNMP) Management

Information Base (MIB) management.

Key Features

The NETGEAR WG302 provides solid functionality, including these features:

• Multiple Operating Modes
– Wireless Access Point. Operates as a standard 802.11g.
– Point-to-Point Bridge. In this mode, the WG302 only communicates with another

bridge-mode wireless station. You must enter the MAC address (physical address) of the
other bridge-mode wireless station in the field provided. WEP should be used to protect
this communication.

– Point-to-Multi-Point Bridge. Select this only if this WG302 is the “Master” for a group

of bridge-mode wireless stations. The other bridge-mode wireless stations must be set to
Point-to-Point Bridge mode, using this WG302's MAC address. They then send all traffic
to this “Master”, rather than communicate directly with each other . WEP should be used to
protect this traffic.

– Wireless Repeater. In this half-duplex mode, the WG302 only communicates with

another repeater-mode wireless station. You must enter the MAC address (physical
address) of the both adjacent repeater-mode wireless stations in the fields provided. WEP
should be used to protect this communication.

• Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded easily,
using only your Web browser, and can be upgraded remotely.

• Access Control. The Access Control MAC address filtering feature can ensure that only
trusted wireless stations can use the WG302 to gain access to your LAN.

2-2 Introduction

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

• Simple Configuration. If the default settings are unsuitable, they are easy to change.

• Hidden Mode. The SSID is not broadcast, assuring only clients configured with the correct
SSID can connect.

• Secure Telnet Command Line Interface. The Telnet command line interface enables direct
access over the serial port and easy scripting of configuration of multiple WG302 across an
extensive network via the Ethernet interface. An SSH client is required.

• Configuration Backup. Configuration settings can be backed up to a file and restored.

• Secure and Economical Operation. Adjustable power output allows more secure or
economical operation.

• Power over Ethernet. Power can be supplied to the WG302 over the Ethernet port from any

802.3af compliant mid-span or end-span source such as the NETGEAR FSM7326P Managed
Power over Ethernet Layer 3 managed switch.

• Autosensing Ethernet Connection with
IEEE 802.3 Ethernet networks.

• LED Indicators. Power, test, LAN speed, LAN activity, and wireless activity are easily
identified.

Auto Uplink Interface. Connects to 10/100 Mbps

802.11g Standards-based Wireless Networking

The WG302 802.11g ProSafe Wireless Access Point provides a bridge between Ethernet wired
LANs and 802.11g compatible wireless LAN networks. It provides connectivity between Ethernet
wired networks and radio-equipped wireless notebook systems, desktop systems, print servers, and
other devices. Additionally, the WG302 supports the following wireless features:

• Distributed coordinated function (CSMA/CA, Back off procedure, ACK procedure,
retransmission of unacknowledged frames)

• RTS/CTS handshake

• Beacon generation

• Packet fragmentation and reassembly

• Short or long preamble

• Roaming among access points on the same subnet

Autosensing Ethernet Connections with Auto Uplink

The WG302 can connect to a standard Ethernet network. The LAN interface is autosensing and
capable of full-duplex or half-duplex operation.

Introduction 2-3

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

The wireless access point incorporates Auto UplinkTM technology. The Ethernet port will
automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’
connection such as to a PC or an ‘uplink’ connection such as to a switch or hub. That port will then
configure itself to the correct configuration. This feature also eliminates any concerns about
crossover cables, as Auto Uplink will accommodate either type of cable to make the right
connection.

Chapter 3

Basic Installation and Configuration

This chapter describes how to set up your WG302 802.11g ProSafe Wireless Access Point for
wireless connectivity to your LAN. This basic configuration will enable computers with 802.11b
or 802.11g wireless adapters to do such things as connect to the Internet, or access printers and
files on your LAN.

Note: Indoors, computers can connect over 802.11g wireless networks at ranges

of several hundred feet or more. This distance can allow for others outside your area

to access your network. It is important to take appropriate steps to secure your network
from unauthorized access. The WG302 Access Point provides highly effective security
features which are covered in detail in Chapter 3, “Configuring Your Wireless Network.
Deploy the security features appropriate to your needs.

You need to prepare these three things before you can establish a connection through your wireless
access point:

• A location for the WG302 that conforms to the Observing Placement and Range Guidelines
below.

• The wireless access point connected to your LAN through a device such as a hub, switch,
router, or Cable/DSL gateway.

• One or more computers with properly configured 802.11b or 802.11g wireless adapters.

Observing Placement and Range Guidelines

The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless access point. The latency, data throughput performance, and
notebook power consumption of wireless adapters also vary depending on your configuration
choices.

Basic Installation and Configuration 3-1

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Note: Failure to follow these guidelines can result in significant performance

degradation or inability to wirelessly connect to the WG302. For complete performance
specifications, see Appendix A, “Specifications”.

For best results, place your wireless access point:

• Near the center of the area in which your PCs will operate.

• In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls).

• Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones.

• Away from large metal surfaces.

• If using multiple access points, it is better if adjacent access points use different

radio frequency

Channels to reduce interference. The recommended Channel spacing between adjacent access
points is 5 Channels (for example, use Channels 1 and 6, or 6 and 11).

The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook PC.

Cabling Requirements

The WG302 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with
RJ-45 connectors.

Understanding WG302 Wireless Security Options

Unlike wired network data, your wireless data transmissions can be received well beyond your
walls by anyone with a compatible adapter. For this reason, use the security features of your
wireless equipment. The WG302 Access Point provides highly effective security features which
are covered in detail in this chapter. Deploy the security features appropriate to your needs.

Figure 3-1: WG302 wireless data security options

There are several ways you can enhance the security of your wireless network:

• Restrict Access Based on MAC address. You can restrict access to only trusted PCs so that
unknown PCs cannot wirelessly connect to the WG302. MAC address filtering adds an
obstacle against unwanted access to your network, but the data broadcast over the wireless link
is fully exposed.

• Turn Off the Broadcast of the Wireless Network Name (SSID). If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network ‘discovery’ feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.

• Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most determined
eavesdropper.

4VERIFY WIRELESS CONNECTIVITY

Using a computer with an 802.11b or 802.11g wireless adapter with the correct wireless
settings needed to connect to the WG302 (SSID, WEP, MAC ACL, etc.), verify connectivity
by using a browser such as Netscape or Internet Explorer to browse the Internet, or check for
file and printer access on your network.

Note: If you are unable to connect, see Chapter 6, “Troubleshooting.”
Enter the default user name of admin and the default password of password.

3-7 Basic Installation and Configuration

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

How to Log In to the WG302 Using Its Default IP Address

1. 192.168.0.228 is the default IP address of your access point. However, the WG302 is also set,

by default, to be a DHCP client. So, if the WG302 has not yet been installed, and there is no
DHCP server on the network, you can log in to the WG302 using its default IP address. You
should use either the NetBIOS name printed on the bottom label to log in.

Note: The computer you are using to connect to the WG302 should be configured with an IP
address that starts with 192.168.0.x and a Subnet Mask of 255.255.255.0.

2. Open a Web browser such as Internet Explorer or Netscape Navigator.

3. Connect to the WG302 by entering its default address of http://192.168.0.228 into your

browser.

4. A login window like the one shown below opens:

Figure 3-3: Login window

Log in use the default user name of admin and default password of password.
Once you have entered your access point name, your Web browser should automatically find

the WG302 Access Point and display the home page, as shown i n “Login result: WG302 home

page” on page 3-6.

Basic Installation and Configuration 3-8

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Understanding Basic Wireless Settings

To configure the wireless settings of your wireless access point, click the Wireless Settings link in
the Basic section of the main menu of the browser interface. The Basic Wireless Settings menu
will appear, as shown below.

Figure 3-4: Basic Wireless Settings menu

The Basic Wireless Settings menu options are discussed below:

• Wireless Network Name (SSID). The SSID is also known as the wireless network name.
Enter a value of up to 32 alphanumeric characters. In a setting where there is more than one
wireless network, different wireless network names provide a means for separating the traffic.
Any device you want to participate in a particular wireless network will need to use the SSID.
The WG302 default SSID is: NETGEAR.

– A group of Wireless Stations and a single access point, all using the same ID (SSID), form

a Basic Service Set (BSS).

– Using the same SSID is essential. Devices with different SSIDs are unable to

communicate with each other. However, some access points allow connections from
wireless stations which have their SSID set to “any” or whose SSID is blank (null).

– A group of wireless stations and multiple access points, all using the same ID (ESSID),

form an Extended Service Set (ESS).

3-9 Basic Installation and Configuration

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

– Different access points within an ESS can use different channels. T o reduce interference, it

is recommended that adjacent access points should use different channels.

– As wireless stations physically move through the area covered by an ESS, they will

automatically change to the access point which has the least interference or best
performance. This capability is called roaming.

• Broadcast Wireless Network Name (SSID). This field lets you turn off the SSID broadcast.
If you turn off the SSID broadcast, only stations that know the SSID will connect. Disabling
SSID broadcast somewhat hampers the wireless network ‘discovery’ feature of some products.
The default is to enable SSID broadcast.

• Country/Region. This field identifies the region where the WG302 can be used. It may not be
legal to operate the wireless features of the wireless access point in a region other than one of
those identified in this field. There is no default country domain, and the channel is set to 11.
Unless a country domain is selected, the channel cannot be changed.

• Operating Mode. Select the desired wireless operating mode. The options are:
– Auto (11g and 11b) – Both 802.11g and 802.11b wireless stations can be used. This is the

default

– 11g Only - Only 8 02.1 1g wireless stations can be used. This is required for 10 8 Mbps data

rate operation.

– 11b Only - All 802.1 1b wireless stations can be used. 802.1 1g wireless stations can still be

used if they can operate in 802.11b mode.

• Channel. This field identifies which operating frequency will be used. It should not be
necessary to change the wireless channel unless you notice interference problems or setting up
the WG302 near another access point. See “Wireless Channels” on page B-7 for more
information on wireless channels.

– Access points use a fixed channel. You can select the channel used. This allows you to

choose a channel which provides the least interference and best performance. In the USA
and Canada, 11 channels are available.

Note: Channel 6 is required for 108 Mbps data rate.

– If using multiple access points, it is better if adjacent access points use different channels

to reduce interference. The recommended channel spacing between adjacent access points
is 5 channels (for example, use channels 1 and 6, or 6 and 11).

– In "Infrastructure" mode, wireless stations normally scan all channels, looking for an

access point. If more than one access point can be used, the one with the strongest signal is
used. This can only happen when the various access points are using the same SSID.

Basic Installation and Configuration 3-10

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

• Data Rate. Shows the available transmit data rate of the wireless network. 108 Mbps is only
available when the operating mode is 802.11g only and the channel is 6. The default is Best.

• Output Power. Set the transmit signal strength of the access point. The options are full, half,
quarter, eighth, and min. Decrease the transmit power if more than one AP is co-located using
the same channel frequency. The default is Full.

RADIUS server.

• Shared: this is for shared key authentication. The SSID and data are encrypted.
Y ou can select the followin g data encryption o ptions:

• Disabled

• 64- 128- or 152-bit WEP
With Open System Authentication and 64- 128- or 152-bit WEP Data Encryption,
the WG302 does perform data encryption but does not perform any
authentication.

If WEP is enabled, you can manually or automatically program the four data
encryption keys. These values must be identical on all PCs and access points in
your network (key 1 must be the same for all, key 2 must be the same for all, etc.)
There are two methods for creating WEP encryption keys:

• Passphrase.

These characters are case sensitive.
Enter a word or group of printable characters in the Passphrase box and click the
Generate button.

Note: Not all wireless adapters support passphrase key generation.

• Manual.

These values are not case sensitive.

64-bit WEP: enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F).
128-bit WEP: enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F).

Information to Gather Before Changing Basic Wireless Settings

Before customizing your wireless settings, print this form and record the following information. If
you are working with an existing wireless network, the person who set up or is responsible for the
network will be able to provide this information. Otherwise, you will choose the settings for your
wireless network. Either way, record the settings for your wireless network in the spaces below.

• Wireless Network Name (SSID): ______________________________

The SSID, identifies
the wireless network. You can use up to 32 alphanumeric characters. The SSID is case
sensitive.

Note: The SSID in the wireless adapter card must match the SSID of the wireless access point.
In some configuration utilities (such as in Windows XP), the term “wireless network name” is
used instead of SSID.

• Authentication. Circle one: Open System or Shared Key.

Authentication is unrelated to encryption of data transmissions. Shared Key provides more
network access security.

Note: If you select Shared Key, the other devices in the network will not connect unless they
are set to Shared Key as well and are configured with the correct key.

• WEP Encryption key size. Choose one: 64- 128- or 152-bit. Larger bit sizes provide stronger

data security. Again, the encryption key size must be the same for the wireless adapters and the
wireless access point.

• Data Encryption (WEP) Keys.

There are two methods for creating WEP data encryption keys. Whichever method you use,
record the key values in the spaces below.

– Passphrase method. ______________________________

These characters are case
sensitive. Enter a word or group of printable characters. When you enter the Passphrase
and click the Generate Key button on the WG302, the keys will be generated.

– Manual method. These values are not case sensitive. For 64-bit WEP, enter 10 hex digits

(any combination of 0-9 or a-f). For 128-bit WEP, enter 26 hex digits. For 152-bit WEP,
enter 32 hex digits.

Viewing a List of Attached Devices

The Station List menu contains a table of all IP devices associated with the wireless access point in
the wireless network defined by the Wireless Network Name (SSID). From the main menu of the
browser interface, under the Information heading, click the Station List link to view the list, shown
below.

Figure 4-4: Information Station List of associated devices

For each device, the table shows the MAC address and whether the device is allowed to
communicate with the wireless access point or not. Note that if the wireless access point is
rebooted, the table data is lost until the wireless access point rediscovers the devices. To force the
wireless access point to look for associated devices, click the Refresh button.

Note: A wireless network can include multiple wireless access points, all using the same network
name (SSID). This enables extending the reach of the wireless network and allows users to roam
from one access point to another, providing seamless network connectivity. Under these
circumstances, be aware that only the stations associated with this access point will be presented in
the Station List.

Upgrading the Wireless Access Point Software

.

Note: When uploading software to the WG302 Access Point, it is important not to
interrupt the W eb browser by closing the wind ow , clicking a link, or loading a new page.
If the browser is interrupted, the upload may fail, corrupt the software, and render the
WG302 completely inoperable.

You cannot perform the firmware upgrade from a workstation connected to the WG302 via a
wireless link. The firmware upgrade must be performed via a workstation connected to the
WG302 via the Ethernet LAN interface.

The software of the WG302 Access Point is stored in FLASH memory, and can be upgraded as
new software is released by NETGEAR. Upgrade files can be downloaded from Netgear's Web
site. If the upgrade file is compressed (.ZIP file), you must first extract the image (.RMG) file
before sending it to the wireless access point. The upgrade file can be sent using your browser.

Note: The Web browser used to upload new firmware into the WG302 must support HTTP
uploads, such as Microsoft Internet Explorer 6.0 or above, or Netscape Navigator 4.78 or above.

1. Download the new software file from NETGEAR, save it to your hard disk, and unzip it.

2. From the main menu Management section, click the Upgrade Firmware link to display the

screen above.

3. In the Upgrade Firmware menu, click the Browse button and browse to the location of the

image (.RMG) upgrade file.

4. Click Upload.

When the upload completes, your wireless access point will automatically restart. The upgrade
process typically takes about one minute.

In some cases, you may need to reconfigure the wireless access point after upgrading.

Wireless Networking Basics

This chapter provides an overview of wireless networking and security.

Wireless Networking Overview

The WG302 Access Point conforms to the Institute of Electrical and Electronics Engineers (IEEE)

802.11g standard for wireless LANs (WLANs). On an 802.1 1g wireless link, data i s encoded using

direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio
spectrum at 2.5GHz. The maximum data rate for the wireless link is 11 Mbps, but it will
automatically back down from 11 Mbps to 5.5, 2, and 1 Mbps when the radio signal is weak or
when interference is detected.

The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet
Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standard group promoting
interoperability among 802.11 devices. The 802.11 standard offers two methods for configuring a
wireless network - ad hoc and infrastructure.

Infrastructure Mode

With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This
mode provides wireless connectivity to multiple wireless network devices within a fixed range or
area of coverage, interacting with wireless nodes via an antenna.

In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet
data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access
Points via a wired Ethernet backbone can further extend the wireless network coverage. As a
mobile computing device moves out of the range of one access point, it moves into the range of
another. As a result, wireless clients can freely roam from one Access Point domain to another and
still maintain seamless network connection.

Wireless Networking Basics B-1

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Ad Hoc Mode (Peer-to-Peer Workgroup)

In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed
points to the network - each node can generally communicate with any other node. There is no
Access Point involved in this configuration. This mode enables you to quickly set up a small
wireless workgroup and allows workgroup members to exchange data or share printers as
supported by Microsoft networking in the various W indows operating systems. Some vendors also
refer to ad hoc networking as peer-to-peer group networking.

In this configuration, network packets are directly sent and received by the intended transmitting
and receiving stations. As long as the stations are within range of one another, this is the easiest
and least expensive way to set up a wireless network.

Network Name: Extended Service Set Identification (ESSID)

The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification
(SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification
(BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is
used, but may still be referred to as SSID.

An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of the
wireless local area network. Some vendors refer to the SSID as network name. For the wireless
devices in a network to communicate with each other, all devices must be configured with the
same SSID.

Authentication, WEP, and WPA

The absence of a physical connection between nodes makes the wireless links vulnerable to
eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11
standard has defined two types of authentication methods, Open System and Shared Key. With
Open System authentication, a wireless PC can join any network and receive any messages that are
not encrypted. With Shared Key authentication, only those PCs that possess the correct
authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an
Open System network. Recently, Wi-Fi, the Wireless Ethernet Compatibility Alliance
(http://www.wi-fi.net) developed the Wi-Fi Protected Access (WPA), a new strongly enhanced
Wi-Fi security. WPA will soon be incorporated into the IEEE 802.11 standard.

B-2 Wireless Networking Basics

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

802.11 Authentication

The 802.11 standard defines several services that govern how two 802.11 devices communicate.
The following events must occur before an 802.11 Station can communicate with an Ethernet
network through an access point such as the one built in to the WG302:

1. Turn on the wireless station.

2. The station listens for messages from any access points that are in range.

3. The station finds a message from an access point that has a matching SSID.

4. The station sends an authentication request to the access point.

5. The access point authenticates the station.

6. The station sends an association request to the access point.

7. The access point associates with the station.

8. The station can now communicate with the Ethernet network through the access point.

An access point must authenticate a station before the station can associate with the access point or
communicate with the network. The IEEE 802.11 standard defines two types of authentication:
Open System and Shared Key.

• Open System Authentication allows any device to join the network, assuming that the device

SSID matches the access point SSID. Alternatively, the device can use the “ANY” SSID
option to associate with any available Access Point within range, regardless of its SSID.

• Shared Key Authentication requires that the station and the access point have the same WEP

Key to authenticate. These two authentication procedures are described below.

Open System Authentication

The following steps occur when two devices use Open System Authentication:

1. The station sends an authentication request to the access point.

2. The access point authenticates the station.

3. The station associates with the access point and joins the network.

This process is illustrated in below.

Shared Key Authentication

The following steps occur when two devices use Shared Key Authentication:

1. The station sends an authentication request to the access point.

2. The access point sends challenge text to the station.

3. The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and

sends the encrypted text to the access point.

4. The access point decrypts the encrypted text using its configured WEP Key that corresponds

to the station’s default key. The access point compares the decrypted text with the original
challenge text. If the decrypted text matches the original challenge text, then the access point
and the station share the same WEP Key and the access point authenticates the station.

5. The station connects to the network.

If the decrypted text does not match the original challenge text (i.e., the access point and station do
not share the same WEP Key), then the access point will refuse to authenticate the station and the
station will be unable to communicate with either the 802.11 network or Ethernet network.

This process is illustrated in below.

Figure 6-2: 802.11 shared key authentication

Overview of WEP Parameters

Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured
to operate in Shared Key authentication mode. There are two shared key methods implemented in
most commercially available products, 64-bit and 128-bit WEP data encryption.

Before enabling WEP on an 802.11 network, you must first consider what type of encryption you
require and the key size you want to use. Typically, there are three WEP Encryption options
available for 802.11 products:

1. Do Not Use WEP: The 802.11 network does not encrypt data. For authentication purposes, the
network uses Open System Authentication.

2. Use WEP for Encryption: A transmitting 802.11 device encrypts the data portion of every
packet it sends using a configured WEP Key. The receiving 802.1 1g device decry pts the data using
the same WEP Key. For authentication purposes, the 802.11g network uses Open System
Authentication.

3. Use WEP for Authentication and Encryption: A transmitting 802.11 device encrypts the data
portion of every packet it sends using a configured WEP Key. The receiving 802.11 device
decrypts the data using the same WEP Key. For authentication purposes, the 802.11 network uses
Shared Key Authentication.

Wireless Networking Basics B-5

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key
Authentication without data encryption). However, the WG302 does not offer this option.

Key Size

The IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit.
The 64-bit WEP data encryption method, allows for a five-character (40-bit) input. Additionally,

24 factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24
factory-set bits are not user-configurable). This encryption key will be used to encrypt/decrypt all
data transmitted via the wireless interface. Some vendors refer to the 64-bit WEP data encryption
as 40-bit WEP data encryption since the user-configurable portion of the encryption key is 40 bits
wide.

The 128-bit WEP data encryption method consists of 104 user-configurable bits. Similar to the
forty-bit WEP data encryption method, the remaining 24 bits are factory set and not user
configurable. Some vendors allow passphrases to be entered instead of the cryptic hexadecimal
characters to ease encryption key entry.

128-bit encryption is stronger than 40-bit encryption, but 128-bit encryption may not be available
outside of the United States due to U.S. export regulations.

When configured for 40-bit encryption, 802.11 products typically support up to four WEP Keys.
Each 40-bit WEP Key is expressed as 5 sets of two hexadecimal digits (0-9 and A-F). For
example, “12 34 56 78 90” is a 40-bit WEP Key.

When configured for 128-bit encryption, 802.11g products typically support four WEP Keys but
some manufacturers support only one 128-bit key . The 128-bit WEP Key is expressed as 13 sets of
two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90 AB CD EF 12 34 56 78 90”
is a 128-bit WEP Key.

Note: Typically, 802.11 access points can store up to four 128-bit WEP Keys but some 802.11
client adapters can only store one. Therefore, make sure that your 802.11 access and client
adapters configurations match.

B-6 Wireless Networking Basics

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

WEP Configuration Options

The WEP settings must match on all 802.11 devices that are within the same wireless network as
identified by the SSID. In general, if your mobile clients will roam between access points, then all
of the 802.11 access points and all of the 802.11 client adapters on the network must have the same
WEP settings.

Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter
in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client
adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc.

Note: The AP and the client adapters can have different default WEP Keys as long as the keys are
in the same order. In other words, the AP can use WEP key 2 as its default key to transmit while a
client adapter can use WEP key 3 as its default key to transmit. The two devices will communicate
as long as the AP’s WEP key 2 is the same as the client’s WEP key 2 and the AP’s WEP key 3 is
the same as the client’s WEP key 3.

Wireless Channels

IEEE 802.11g wireless nodes communicate with each other using radio frequency signals in the
ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring
channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending
signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the
center channel frequency. As a result, two separate wireless networks using neighboring channels
(for example, channel 1 and channel 2) in the same general vicinity will interfere with each other.
Applying two channels that allow the maximum channel separation will decrease the amount of
channel cross-talk, and provide a noticeable performance increase over networks with minimal
channel separation.

Wireless Networking Basics B-7

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

The radio frequency channels used are listed in Table B-1:

Table B-1. 802.11g Radio Frequency Channels

Channel Center Frequency Frequency Spread

1 2412 MHz 2399.5 MHz - 2424.5 MHz
2 2417 MHz 2404.5 MHz - 2429.5 MHz
3 2422 MHz 2409.5 MHz - 2434.5 MHz
4 2427 MHz 2414.5 MHz - 2439.5 MHz
5 2432 MHz 2419.5 MHz - 2444.5 MHz
6 2437 MHz 2424.5 MHz - 2449.5 MHz
7 2442 MHz 2429.5 MHz - 2454.5 MHz
8 2447 MHz 2434.5 MHz - 2459.5 MHz
9 2452 MHz 2439.5 MHz - 2464.5 MHz
10 2457 MHz 2444.5 MHz - 2469.5 MHz
11 2462 MHz 2449.5 MHz - 2474.5 MHz
12 2467 MHz 2454.5 MHz - 2479.5 MHz
13 2472 MHz 2459.5 MHz - 2484.5 MHz

Note: The available channels s upporte d by the wireless products in various countries are dif ferent.

The preferred channel separation between the channels in neighboring wireless networks is 25
MHz (5 channels). This means that you can apply up to three different channels within your
wireless network. There are only 11 usable wireless channels in the United States. It is
recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as
these three channels do not overlap.

802.1x

802.1x defines port-based, network access control used to provide authenticated network access and
automated data encryption key management.
The IEEE 802.1x draft standard offers an effective framework for authenticating and controlling user traffic
to a protected network, as well as dynamically varying encryption keys. 802.1x uses a protocol called EAP
(Extensible Authentication Protocol) and supports multiple authentication methods, such as token cards,
Kerberos, one-time passwords, certificates, and public key authentication. For details on EAP specifically,
refer to IETF's RFC 2284.

802.11b

IEEE specification for wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS)
technology and operating in the unlicensed radio spectrum at 2.5GHz.

802.11g

A soon to be ratified IEEE specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.5GHz. 802.11g is
backwards compatible with 802.11b.

ADSL

Short for asymmetric digital subscriber line, a technology that allows data to be sent over existing copper
telephone lines at data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and
from 16 to 640 Kbps when sending data (known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.

ARP

Address Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called
a DLC address), such as an Ethernet address.
A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host
on the network that has the IP address in the request then replies with its physical hardware address. There is

Glossary

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host
broadcasts its physical address and a RARP server replies with the host's IP address.

Auto Uplink

Auto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
straight-through Ethernet cables. Auto Uplink

TM

will accommodate either type of cable to make the right

connection.

CA

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.

Cat 5

Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.

Certificate Authority

A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.
The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact,
who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution,
such as a credit card company, which provides it with informatio n to confirm an individual's claimed
identity . CAs are a critical component in data security and electronic

commerce because they guarantee that

the two parties exchanging information are really who they claim to be.

DHCP

An Ethernet protocol specifying how a centralized DHCP server can assign network configuration
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and
gateway (router) addresses.

DMZ

Specifying a Default DMZ Server allows you to set up a computer or server that is available to anyone on
the Internet for services that you haven't defined. There are security issues with doing this, so only do this if
you'll willing to risk open access.

DNS

Short for Domain Name System (or Service), an Internet service that translates domain names into IP
addresses.

2 Glossary

December 2003

Reference Manual for the WG302 802.11g ProSafe Wireless Access Point

Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on
IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the
corresponding IP address. For example, the domain name www.example.com might translate to

198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to
translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

Domain Name

A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a
registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For
example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.

DSL

Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this
technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5
to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data
(known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.

Dynamic Host Configuration Protocol

DHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and
gateway (router) addresses.

EAP

Extensible Authentication Protocol is a general protocol for authentication that supports m ultiple
authentication methods.
EAP, an extension to PPP, supports such authentication methods as token cards, Kerberos, one-time
passwords, certificates, public key authentication and smart cards. In wireless communications using EAP, a
user requests connection to a WLAN through an AP, which then requests the identity of the user and
transmits that identity to an authentication server such as RADIUS. The server asks the AP for proof of
identity, which the AP gets from the user and then sends back to the server to complete the authentication.
EAP is defined by RFC 2284.

ESSID

The Extended Service Set Identification (ESSID) is a thirty-two character (maximum) alphanumeric key
identifying the wireless local area network.

Gateway

A local device, usually a router, that connects hosts on a local network to ot her networks.

IP

Internet Protocol is the main internetworking protocol used in the Internet. Used in conjunction with the
Transfer Control Protocol (TCP) to form TCP/IP.

IP Address

A four-byte number uniquely defining each host on the Internet, usually written in dotted-decimal notation
with periods separating the bytes (for example, 134.177.244.57).
Ranges of addresses are assigned by Internic, an organization formed for this purpose.

ISP

Internet service provider.

Internet Protocol

The main internetworking protocol used in the Internet. Used in conjunction with the Transfer Control

local area network

LAN. A communications network serving users within a limited area, such as one floor of a building.
A LAN typically connects multiple personal computers and shared network devices such as storage and
printers. Although many technologies exist to implement a LAN, Ethernet is the most common for
connecting personal computers.

MAC address

The Media Access Control address is a unique 48-bit hardware address assigned to every network interface
card. Usually written in the form 01:23:45:67:89:ab.

Mbps

Megabits per second.

MD5

MD5 creates digital signatures using a one-way hash function, meaning that it takes a message and converts
it into a fixed string of digits, also called a message digest.
When using a one-way hash function, one can compare a calculated message digest against the message
digest that is decrypted with a public key to verify that the message hasn't been tampered with. This
comparison is called a "hashcheck."

MDI/MDIX

In cable wiring, the concept of transmit and receive are from the perspective of the PC, which is wired as a
Media Dependant Interface (MDI). In MDI wiring, a PC transmits on pins 1 and 2. At the hub, switch,
router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is
referred to as Media Dependant Interface - Crossover (MDI-X). See also Auto Uplink.

NAT

A technique by which several hosts share a single IP address for access to the Internet.

NetBIOS

Network Basic Input Output System. An application programming interface (API) for sharing services

and information on l

ocal-area networks (LANs). Provides for communication between stations of a

network where each station is given a name. These names are alphanumeric names, 16 characters in length.

netmask

Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local
to it, and which must be reached through a gateway or router.
A number that explains which part of an IP address comprises the network address and which part is the host
address on that network. It can be expressed in dotted-decimal notation or as a number appended to the IP
address. For example, a 28-bit mask starting from the MSB can be shown as 255.255.255.192 or as /28
appended to the IP address.

Network Address Translation

A technique by which several hosts share a single IP address for access to the Internet.

address, some protocol and length information, a block of data, and a checksum.

Point-to-Point Protocol

PPP. A protocol allowing a computer using TCP/IP to connect directly to the Internet.

RADIUS

Short for Remote Authentication Dial-In User Service, RADIUS is an authentication system.
Using RADIUS, you must enter your user name and password before gaining access to a network. This
information is passed to a RADIUS server, which checks that the information is correct, and then authorizes
access. Though not an official standard, the RADIUS specification is maintained by a working group of the
IETF.

RIP

A protocol in which routers periodically exchange information with one another so that they can determine
minimum distance paths between sources and destinations.

router

A device that forwards data between networks. An IP router forwards data based on IP source and
destination addresses.

to it, and which must be reached through a gateway or router.

TLS

Short for Transport Layer Security, TLS is a protocol that guarantees privacy and data integrity between
client/server applications communicating over the Internet.
The TLS protocol is made up of two layers. The TLS Record Protocol ensures that a connection is private by
using symmetric data encryption and ensures that the connection is reliable. The second TLS layer is the
TLS Handshake Protocol, which allows authentication between the server and client and the negotiation of
an encryption algorithm and cryptographic keys before data is transmitted or received. Based on Netscape’s
SSL 3.0, TLS supercedes and is an extension of SSL. TLS and SSL are not interoperable.
