Chapter 1
Introduction
This chapter introduces the WG103 ProSafe 802.11g Wireless Access Point. Minimal
requirements for installation are in “System Requirements” on page 1-4.
About the Wireless Access Point
The WG103 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 WG103 antenna interacts with wireless network interface cards (NIC) in wireless devices
within a fixed range or area of coverage. Typically, a wireless access point inside a building works
best with devices within a 100 foot radius. The WG103 can support a small group of users in a
range of several hundred feet. Most wireless access points are rated between 30-50 users
simultaneously.
The WG103 acts as a bridge between the wired LAN and wireless clients. Connecting multiple
WG103 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 wireless access point, it
moves into the range of another. As a result, wireless clients can freely roam from one wireless
access point to another and still maintain seamless connection to the network.
Supported Features, Sta ndards, and Conventions
The WG103 is easy to use and provides complete 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. 64-bit, 128-bit, and 152-bit keys are supported.
1-1
v1.0, February 2009
WG103 ProSafe 802.11g Wireless Access Point Reference Manual
• Full WPA and WPA2 support. WPA and WPA2 enterprise class strong security with
RADIUS and certificate authentication as well as dynamic encryption key generation.
WPA-PSK and WPA2-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 WG103 can act as a client and obtain information from your DHPC server.
• Multiple BSSIDs. Support for multiple BSSIDs. When one AP is connected to a wired
network and a set of wireless stations it is referred to as a Basic Service Set (BSS). The Basic
Service Set Identifier (BSSID) is a 32-character unique identifier attached to the header of
packets sent over a WLAN that differentiate one WLAN from another when a mobile device
tries to connect to the network.
• SNMP Support. Support for Simple Network Management Protocol (SNMP) Management
Information Base (MIB) management.
Key Features
The WG103 provides solid functionality, including these features
• Multiple Operating Modes
– Wireless Access Point. Operates as a standard 802.11g wireless access point.
– Point-to-point bridge. In this mode, the WG103 communicates only with another
bridge-mode wireless access point. Y ou must enter the MAC address (physical address) of
the other bridge-mode wireless access point in the field provided. Wireless security should
be used to protect this communication.
– Point-to-multi-point bridge. Select this mode only if this WG103 is the “master” for a
group of bridge-mode wireless access points. The other bridge-mode wireless access
points must be set to point-to-point bridge mode, usi ng the WG103’ s MAC add ress. Th ey
then send all traffic to this “master”, rather than communicate directly with each other.
Wireless security should be used to protect this traffic.
– Wireless repeater. In this half-duplex mode, the WG103 communicates only with another
repeater-mode wireless access point. You must enter the MAC address of both adjacent
repeater-mode wireless access points in the fields provided. Wireless security 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, or remotely with a CLI or through SNMP.
• Access Control. The Access Control MAC address filtering feature can ensure that only
trusted wireless stations can use the WG103 to gain access to your LAN.
1-2 Introduction
v1.0, February 2009
WG103 ProSafe 802.11g Wireless Access Point Reference Manual
• Security Profiles. When using multiple BSSIDs, you can configure unique security settings
(encryption, MAC filtering, etc.) for each BSSID.
• Simple Configuration. If the default settings are unsuitable, they are easy to change.
• Hidden Mode. In this 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.
• Ethernet Interface. Connects to 10/100 Mbps IEEE 802.3 Ethernet networks.
• Power over Ethernet. Power can be supplied to the WG103 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.
• LED Indicators. Power, test, LAN speed, LAN activity, and wirele ss activity are easily
identified.
• VLAN Support. Short for virtual LAN, a network of computers that behave as if they are
connected to the same network even though they may actually be physically located on
different segments of a LAN. VLANs are configured through software rather than hardware,
which makes them extremely flexible. VLANs are very useful for user/host management,
bandwidth allocation and resource optimization.
802.11g Standards-based Wireless Networking
The WG103 provides a bridge between Ethernet wired LANs and 802.11g compatible wireless
LAN networks. The WG103 also 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 wireless access points on the same subnet
• Super G—a proprietary chipset feature that has been developed to give wireless data rates of
up to 108 Mbps. This higher throughput is achieved by having the features–bursting,
compression, dynamic turbo, and fast frames–together.
Introduction 1-3
v1.0, February 2009
WG103 ProSafe 802.11g Wireless Access Point Reference Manual
Wi-Fi Multimedia (WMM) Support
WMM is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of
priorities, depending on the kind of data. Time-dependent information, like video or audio, has a
higher priority than normal traffic. For WMM to function correctly, wireless clients must also
support WMM.

Basic Installation and Configuration
This chapter describes how to install and configure your WG103 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 adapters to connect to the Internet, or access printers and files on your
LAN. In planning your wireless network, consider the level of security required. Chapter 3,
“Wireless Security” describes how to set up wireless security for your network.
This chapter includes:
• “What You Need before You Begin” on this page
• “Installing and Configuring the Wireless Access Point” on page 2-2
• “Testing Basic Wireless Connectivity” on page 2-12
• “Deploying the Wireless Access Point” on page 2-12
What You Need before You Begin
You need to consider the following guidelines and requirements before you can set up your
wireless access point. See also “System Requirements” on page 1-4.
Wireless Equipment Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the location of the wireless
access point. The latency, data throughput performance, and notebook power consumption of
wireless adapters also vary depending on your configuration choices.
Note: Failure to follow these guidelines can result in significant performance degradation
or inability to wirelessly connect to the wireless access point. For complete
performance specifications, see Appendix A, “Technical Specifications.”
For best results, place your wireless access point according to the following guidelines:
• 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-ofsight access (even if through walls).

v1.0, February 2009
WG103 ProSafe 802.11g Wireless Access Point Reference Manual
• Away from sources of interference, such as PCs, microwaves ovens, and 2.4 GHz cordless
phones.
• Away from large metal surfaces or water.
• 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 wireless access points, it is better if adjacent wireless access points use
different radio frequency channels to reduce interference. The recommended channel spacing
between adjacent wireless access points is five channels (for example, use channels 1 and 6, or
6 and 11, or 1 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.
Ethernet Cabling Requirements
The wireless access point connects to your LAN via twisted-pair category 5 Ethernet cable with
RJ-45 connectors.
LAN Configuration Requirements
For the initial configuration of your wireless access point, you need to connect a computer to the
wireless access point.
Note: For assistance with DHCP configuration, see the online document that you can
access from “Preparing Your Network” in Appendix B.
Computer Hardware Requirements
To connect to the wireless access point on your network, each computer must have a 802.11g or
802.11b wireless adapter installed.
Installing and Configuring the Wireless Access Point
Before installing the wireless access point, make sure that your Ethernet network is up and
working. You will be connecting the wireless access point to the Ethernet network. Then
computers with 802.11b or 802.11g wireless adapters will be able to communicate with the
Ethernet network.

subnet mask.
4. Connect an Ethernet cable from the wireless access point to the computer.
5. Turn on your computer, connect the power adapter to the wireless access point, and verify the
following:
• Power LED. The power LED (PWR) should be lit. If the power LED is not lit, check the
connections and check to see if the power outlet is controlled by a wall switch that is
turned off.
• Test LED. The test LED (TEST) blinks when the wireless a ccess point is first turned on.
• LAN LED. The LAN LED (LAN) on the wireless access point should be lit (amber for a
