RangeMax™ 240 Multiple-Input, Multiple-Output (MIMO)

Technology

NETGEAR’s RangeMax 240 Multiple-Input, Multiple-Output (MIMO) technology provides ten

times more coverage than standard 802.11g alone by eliminating “dead spots” in your area of

coverage. Your whole house or office suite now becomes a “hot spot” without requiring any range

extenders, repeaters, or external antennas. RangeMax maintains your high speed throughout your

home, not just when you are close to your router.

RangeMax 240 is a TRUE MIMO (Multiple Input, Multiple Output) technology that uses three

external antennas, capable of transmitting at speeds up to 240 Mbps. It can also transmit two

different data streams on the same channel at the same time, at speeds up to 126 Mbps, if you use

the WPNT511 or WPNT121 Wireless Adapters.

In "Up to 240 Mbps" mode the router uses channel expansion to achieve a data rate of 240 Mbps.

The channel expansion uses the channel selected as the primary channel and expands to a

secondary channel (primary channel + 4 or - 4) to achieve a frame-by-frame bandwidth of

40 MHz. The WPNT834 router detects channel usage and, if necessary, will disable frame-by-

frame expansion to avoid interference with the data transmission from other access points or

clients.

Note: The maximum wireless signal rate is derived from the IEEE Standard 802.11

Specifications. Actual data throughput will vary. Network conditions and

environmental factors, including volume of network traffic, building materials

and construction, and network overhead, lower actual data throughput rate.

Introduction 2-3

v1.1, January 2006

RangeMax 240 is also 100% compatible with your existing 802.11b/g products (i.e., 802.11b,

802.11g, and Centrino wireless clients) and boosts their range and speed by up to 50%.

802.11g Wireless Networking

The WPNT834 router includes an 802.11g wireless access point, providing continuous, high-speed

240 Mbps access between your wireless and Ethernet devices. The access point provides:

• 802.11g wireless networking at up to 240 Mbps.

• 802.11g wireless networking, with the ability to operate in Up to 240 Mbps, Up to 126 Mbps,

802.11g-only, or 802.11g and b modes, providing backwards compatibility with 802.11b or

802.11g devices or dedicating the wireless network to the higher bandwidth devices.

• 64-bit and 128-bit WEP encryption security.

• WEP keys can be generated manually or by passphrase.

• WPA-PSK and WPA2-PSK support. Support for Wi-Fi Protected Access (WPA) data

encryption which provides strong data encryption and authentication based on a pre-shared

key. WPA-PSK and WPA2-PSK will block eavesdropping. Because these are new standards,

wireless device driver and software availability may be limited.

• Wireless access can be restricted by MAC address.

• Wireless network name broadcast can be turned off so that only devices that have the network

name (SSID) can connect.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the WPNT834 is a true firewall, using stateful packet

inspection to defend against hacker attacks. Its firewall features include:

• Denial of Service (DoS) protection.

Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND

Attack, and IP Spoofing.

• Blocks unwanted traffic from the Internet to your LAN.

• Blocks access from your LAN to Internet locations or services that you specify as off-limits.

• Logs security incidents.

The WPNT834 will log security events such as blocked incoming traffic, port scans, attacks,

and administrator logins. You can configure the router to E-mail the log to you at specified

intervals. You can also configure the router to send immediate alert messages to your E-mail

address or E-mail pager whenever a significant event occurs.

2-4 Introduction

v1.1, January 2006

• Keyword screening.

The WPNT834 prevents objectionable content from reaching your computers. The router

allows you to control access to Internet content by screening for keywords within Web

addresses. You can configure the router to log and report attempts to access objectionable

Internet sites.

Security

The WPNT834 router is equipped with several features designed to maintain security, as described

in this section.

• Computers Hidden by NAT.

NAT opens a temporary path to the Internet for requests originating from the local network.

Requests originating from outside the LAN are discarded, preventing users outside the LAN

from finding and directly accessing the computers on the LAN.

• Port Forwarding with NAT.

Although NAT prevents Internet locations from directly accessing the computers on the LAN,

the router allows you to direct incoming traffic to specific computers based on the service port

number of the incoming request, or to one designated “DMZ” host computer. You can specify

forwarding of single ports or ranges of ports.

Autosensing Ethernet Connections with Auto Uplink

With its internal 4-port 10/100 switch, the WPNT834 can connect to either a 10 Mbps standard

Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are

autosensing and capable of full-duplex or half-duplex operation.

The router incorporates Auto UplinkTM technology. Each 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 the need to worry about crossover cables,

as Auto Uplink will accommodate either type of cable to make the right connection.

Extensive Protocol Support

The WPNT834 router supports the Transmission Control Protocol/Internet Protocol

(TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, see

“Wireless Communications” in Appendix B.

• IP Address Sharing by NAT.

Reference Manual for the RangeMax 240 Wireless Router WPNT834

Introduction 2-5

v1.1, January 2006

The WPNT834 router allows several networked computers to share an Internet account using

only a single IP address, which your Internet service provider (ISP) may statically or

dynamically assign. This technique, known as NAT, allows the use of an inexpensive single-

user ISP account.

• Automatic Configuration of Attached Computers by DHCP.

The WPNT834 router dynamically assigns network configuration information, including

IP, gateway, and domain name server (DNS) addresses, to attached computers on the LAN

using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies

configuration of computers on your local network.

• DNS Proxy.

When DHCP is enabled and no DNS addresses are specified, the router provides its own

address as a DNS server to the attached computers. The router obtains actual DNS addresses

from the ISP during connection setup and forwards DNS requests from the LAN.

• PPP over Ethernet (PPPoE).

PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by

simulating a dial-up connection. This feature eliminates the need to run a login program such

as Entersys or WinPOET on your computer.

Easy Installation and Management

You can install, configure, and operate the RangeMax 240 Wireless Router WPNT834 within

minutes after connecting it to the network. The following features simplify installation and

management tasks:

• Browser-based management.

Browser-based configuration allows you to easily configure your router from almost any type

of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is

provided and online help documentation is built into the browser-based Web Management

Interface.

• Smart Wizard.

The WPNT834 router Smart Wizard automatically senses the type of Internet connection,

asking you only for the information required for your type of ISP account.

• Firmware Update.

The WPNT834 router can be updated if a newer version of firmware is available. This lets you

take advantage of product enhancements for your WPNT834 as soon as they become

available.

A Road Map for ‘How to Get There From Here’

The introduction and adoption of any new technology can be a difficult process. Broadband

Internet service is considered so useful that more and more people want to set up networks in their

home to share a broadband connection. Wireless technology has removed one of the barriers to

networking—running wires. It allows more people to try networking while at the same time

exposes them to the inherent complexity of networking. General networking concepts, setup, and

maintenance can be difficult to understand. In addition, wireless technology adds issues, such as

range, interference, signal quality, and security to the picture.

To help overcome potential barriers to successfully using home networks, the table below

identifies how to accomplish such things as connecting to a wireless network, assuring appropriate

security measures are taken, browsing the Internet through your wireless connection, exchanging

files with other computers and using printers in the combined wireless and wired network.
