Observe Location and Range Guidelines
Computers can connect over 802.11g wireless networks indoors at a range which vary
significantly based on the physical location of the computer with the NETGEAR 54 Mbps
Wireless PC Card WG511. For best results, avoid potential sources of interference, such as:
•Large meta l surfaces
•Microwaves
•2.4 GHz Cordless phones
In general, 802.11g wireless devices can communicate through walls. However, if the walls are
constructed with co ncr ete, or have metal, or meta l mesh, the 802.11g effective range will decrease
if such materials are between the devices.
Two Basic Operating Modes
The WG511 Wireless PC Card, like all 802.11b adapters, can operate in the following two basic
modes:
•Infrastructure Mode: An 802.11 networking framework in which devices and computers
communicate with each other by first going through an
mode is used when computers i n a house conne ct to an Acc ess Point that is attac hed to a route r
which lets multiple computers share a single Cable or DSL broadband Internet connection.
•Ad-Hoc Mode: An 802.11 networking framework in which devices or computers
communicate directly with each other, without the use of an AP.
is used when two Windows computers are configured with file and print sharing enabled and
you want to exchange files directly between them.
Both of these configuration options are available with the WG511 Wireless PC Card.

Wireless Net w orking Overview
The WG511 Wireless PC Card conforms to the Institute of Electrical and Electronics Engineers
(IEEE) 802.1 1b standar d for wirel ess LAN
into conformance to t he 802.11g standard when it is ratified. On an 802.1 1 b or g wirele ss link, dat a
is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the
unlicensed radio spe ctrum at 2.5GHz. The maxi mum data rate for the wireless l ink is 1 1 Mbps, but
it will automaticall y back do wn from 11 Mbps to 5.5, 2, and 1 Mbps when the radio signal is we ak
or when interference is detected. The 802.11g auto rate sensing rates are 1, 2, 5.5, 6, 9, 12, 18, 24,
36, 48, and 54 Mbps.
s (WLANs) and a product upda te will bri ng the WG51 1
The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet
Compatibility Alliance (WECA, s ee 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 fr eely r oam from on e Access Point d omain to anothe r and
still maintain seamless network connection.
Wireless Networking BasicsB-35
Page 42
Installation Guide for the NETGEAR 54 Mbps Wireless PC Card WG511
Ad Hoc Mode (Peer-to-Peer Workgroup)
In an ad hoc network , computers a re brought together as needed; t hus, th ere is no st ructure 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 Mi croso ft n etworki ng in the vari ous Windows operating systems. Some ve ndors al so
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 S et Identifi cation (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-tw o character (maximum) alphanumeric key i dentifying 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 and WEP
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 auth entication, a wir eless PC can join any net work and r eceive a ny messa ges that a re
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.

Installation Guide for the NETGEAR 54 Mbps Wireless PC Card WG511
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 WG511:
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 wit h the statio n.
8.The station can now communicate with the Ethernet network through the access point.
An access point mus t authent icate a st ation bef ore the st ation ca n associat e with the access poi nt or
communicate with the network. The IEEE 802.11 standard defines two types of authentication:
Open System and Sh ared Key.
•Open System Authenticatio n 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 wi thin 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 be low.

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 decrypt ed t ext do es not match t he or iginal chal lenge text (i. e., th e acce ss po int a nd stat ion 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 be low.

Overview of WEP Parameters
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 us ing a confi gured WEP Key. The receiving 802.1 1b dev ice decry pts th e data using
the same WEP Key. For authentication purposes, the 802.11b network uses Open System
Authentication.
3. Use WEP for Authentication and Encryption: A transmitting 802.1 1 dev ice encrypt s 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.
Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key
Authentication without data encryption).
Wireless Networking BasicsB-39
Page 46
Installation Guide for the NETGEAR 54 Mbps Wireless PC Card WG511
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 si nce th e 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, 802.11b products typically support four WEP Keys but
some manufacturers sup port only one 128-bit key. The 128-bit WEP Key is expressed as 13 s ets 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 matc h.
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 mo bil e c li ent s will roam between access poi nt s, t hen all
of the 802.1 1 acce ss poin ts 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 a ls o en ter t he 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 def au lt WEP Ke ys as lo ng as the keys are
in the same order. In other words, the AP can use WEP key 2 as its defa ul t key to transmit while a
client adapter can us e WEP key 3 as it s def ault key to tr ansmit. The two devi ces wi ll co mmunic ate
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 Channe ls
IEEE 802.11b and g wireless nodes communicate with each ot her usi ng radio frequency signa ls 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 separati on.
Wireless Networking BasicsB-41
Page 48
Installation Guide for the NETGEAR 54 Mbps Wireless PC Card WG511
The radio frequency channels used are listed in Table 3-1:
Note: The available channels supported by the wireless products in va ri ous count ries are different .
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 st art using cha nnel 1 and gr ow to use chann el 6, and 11 when necessary, as
these three channels do not overlap.

Preparing Your PCs for Network Access
This appendix describes how to prepare your PCs to connect to the Internet through the
NETGEAR 54 Mbps Wireless PC Card WG511.
For adding file and print sharing to your network, please consult the Windows help information
included with the version of Windows installed on each computer on your network.
Preparing Your Computers for TCP/IP Networking
Computers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/
Internet Protocol ). Eac h comput er on your network must have TCP/IP installed and sel ect ed as its
networking protocol. If a Network Interface Card (NIC) is already installed in your PC, then TCP/
IP is probably already installed as well.
Most operating systems include the software components you need for networking with TCP/IP.
Windows 95 or later includes the software components for establishing a TCP/IP network.
In your TCP/IP network, each PC and the wireless access point must be assigned a unique IP
addresses. Each PC must also have certain other TCP/IP configuration information such as a
subnet mask (netmask), a domain name server (DNS) address, and a default gateway address. In
most cases, you should install TCP/IP so that the PC obtains its specific network configuration
information automatically from a DHCP server during startup.
Configuring Window s 98 and Me for TCP/IP Networking
As part of the PC preparation process, you may need to install and configure
TCP/IP on your PC. Befo re star ting, loc ate your W indows CD; you may n eed to insert it during the
TCP/IP installation proces s.
