• Consult the dealer or an experienced radio/TV technician for help.
Placement and Range Guidelines
Indoors, computers can connect over 802.11 wireless networks at a maximum range of several hundred feet
for 802.11b/g 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.
RF Exposure Warning for North America, and Australia
Warning! To meet FCC and other national safety guidelines for RF exposure, the antennas for this device
(see below) must be installed to ensure a minimum separation distance of 20cm (7.9 in.) from persons.

Chapter 2
Introduction
This chapter introduces the NETGEAR WG102 ProSafe 802.11g Wireless Access Point. Minimal
prerequisites for installation are presented in “System Requirements” on page 2-4.
About the NETGEAR WG102 ProSafe 802.11g Wireless Access Point
The NETGEAR WG102 ProSafe 802.11g Wireless 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 WG102 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 NETGEAR WG102 ProSafe 802.11g Wireless Access Point can support a
small group of users in a range of several hundred feet. Most access points are rated between 30-50
users simultaneously.
The NETGEAR WG102 ProSafe 802.11g Wireless Access Point acts as a bridge between the
wired LAN and wireless clients. Connecting multiple WG102 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 NETGEAR WG102 ProSafe 802.11g Wireless Access Point
allows packet transmission at up to 108 Mbps, or at reduced speeds to compensate for distance or
electromagnetic interference.
Introduction 2-1
October 2004
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point
Key Features
The WG102 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 Wi reless Access Point complies with the IEEE 802.11g for
Wireless LANs.
• WEP support. Support for WEP is included. 64-bit, 128-bit, and 152-bit keys are supported.
• Full WPA support. WPA enterprise class strong security with RADIUS and certificate
authentication as well as dynamic encryption key generation. WPA-PSK pre-shared key
authentication without the overhead of RADIUS servers but with all of the strong security of
WPA.
• DHCP Client Support. DHCP provides a dynamic IP address to PCs and other devices upon
request. The WG102 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 WG102 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 WG102 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 WG102 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 WG102'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 WG102 only communicates with
another repeater-mode wireless station. You must enter the MAC address of both adjacent
repeater-mode wireless stations in the fields provided. WEP should be used to protect this
communication.
2-2 Introduction

Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point
• 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 WG102 to gain access to your LAN.
• 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.
• Configuration Backup. Configuration settings can be backed up to a file and restored.
• Power over Ethernet. Power can be supplied to the WG102 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.

Reference Manual for the NETGEAR WG102 ProSafe 802.11g 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 computer 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 NETGEAR WG102 ProSafe 802.11g Wireless Access
Point for wireless connectivity to your LAN. This basic configuration will enable computers with
802.11b or 802.1 1g wireless ad apters 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 WG102 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 WG102 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, switc h,
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
October 2004
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the WG102. 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.
• Putting the antenna in a vertical position provides best side-to-side coverage. Putting the
antenna in a horizontal position provides best up-and-down coverage.
• 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 computer.
Cabling Requirements
The WG102 Access Point connects to your LAN via twisted-pair Category 5 Ethernet cable with
RJ-45 connectors.

Understanding WG102 Wireless Security Options
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
WG102 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: WG102 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 WG102. MAC address filtering adds an
obstacle against unwanted access to your network, but the data broadcast over the wireless link
is fully exposed.
• T urn Off the Br oadcast 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.

Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point
• Use WPA or WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data
security. The very strong authentication along with dynamic per frame rekeying of WPA make
it virtually impossible to compromise. Because this is a new standard, wireless device driver
and software availability may be limited.
Installing the WG102 Access Point
Before installing the NETGEAR WG102 ProSafe 802.11g Wireless Access Point, you should
make sure that your Ethernet network is up and working. You will be connecting the access point
to the Ethernet network so that computers with 802.11b or 802.11g wireless adapters will be able
to communicate with computers on the Ethernet network. In order for this to work correctly , verify
that you have met all of the system requirements, shown on page 2-4.
1SET UP THE WG102 ACCESS POINT
Tip: Before mounting the WG102 in a high location, first set up and test the WG102 to verify
wireless network connectivity.
a. Prepare a computer with an Ethernet adapter. If this computer is already part of your
network, record its TCP/IP configuration settings.
b. Configure the computer with a static IP address of 192.168.0.210 an d 255 .2 55. 255 .0 for
the Subnet Mask.
c. Connect an Ethernet cable from the WG102 to the computer.
d. T urn on your computer, connect the power adapter to the WG102 and verify the following:
