Reference Manual for the NETGEAR ProSafe Wireless Access Point 802.11g WG302
2-2
Introduction
July 2005 v3.0
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. 64-bit, 128-bit, and 152-bit keys are supported.
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 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:
AutoCell RF Management.
AutoCell provides advanced automated RF management that
improves performance and enhances security.
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 of both adjacent
repeater-mode wireless stations in the fields provided. WEP should be used to protect this
communication.
Wireless 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 such as video or audio will have a higher priority than normal
traffic. For WMM to function correctly, wireless clients must also support WMM.
Rogue Access Point detection.
For enhanced security, you can scan the wireless network to
detect rogue access points.
Hotspot settings.
You can allow all HTTP (TCP, port 80) requests to be captured and
re-directed to the URL you specify.
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.
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
Auto Uplink
I
nterface.
Connects to 10/100 Mbps
IEEE 802.3 Ethernet networks.
LED Indicators.
Power, test, LAN speed, LAN activity, and wireless activity are easily
identified.
AutoCell—The Self-Organizing Wireless Network
AutoCell
TM
, an embedded control system for 802.11 WLANs. AutoCell increases available
bandwidth and reduces WLAN installation and operating costs significantly.

Introduction
July 2005 v3.0
AutoCell is completely automatic: It is a continuous communication system that relies on a
lightweight protocol to monitor changes on the wireless domain while keeping overhead very low.
Among AutoCell's inherent advantages:
Elimination of manual site surveys and channel maps
Dynamic load balancing
Plug-and-play-implementation
Transparent fault recovery and failover
Since AutoCell is completely self-organizing, it holds human intervention to a minimum. That
reduces the people costs associated with deployment, management, and maintenance—making
802.11 WLANs practical, efficient, and cost-effective.
802.11g Standards-based Wireless Networking
The NETGEAR ProSafe Wireless Access Point 802.11g WG302 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

July 2005 v3.0
The wireless access point incorporates Auto Uplink
TM
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.
