Introduction

The D-Link AirPlus G DI-524UP High-Speed Wireless Router is an 802.11g high-

performance, wireless router that supports high-speed wireless networking at home,

at work or in public places.

Unlike most routers, the DI-524UP provides data transfers at up to 108 Mbps (compared

to the standard 54 Mbps) when used with other D-Link AirPlus G products. The 802.11g

standard is backwards compatible with 802.11b products. This means that you do not

need to change your entire network to maintain connectivity. You may sacriﬁce some of

802.11g’s speed when you mix 802.11b and 802.11g devices, but you will not lose the

ability to communicate when you incorporate the 802.11g standard into your 802.11b

network. You may choose to slowly change your network by gradually replacing the

802.11b devices with 802.11g devices .

In addition to offering faster data transfer speeds when used with other 802.11g

products, the DI-524UP has the newest, strongest, most advanced security features

available today. When used with other 802.11g WPA (WiFi Protected Access) and

802.1x compatible products in a network with a RADIUS server, the security features

include:

WPA: Wi-Fi Protected Access authorizes and identiﬁes users based on a secret key

that changes automatically at a regular interval. WPA uses TKIP (Temporal

Key Integrity Protocol) to change the temporal key every 10,000 packets (a

packet is a kind of message transmitted over a network.) This insures much

greater security than the standard WEP security. (By contrast, the older WEP

encryption required the keys to be changed manually.)

802.1x: Authentication is a ﬁrst line of defense against intrusion. In the Authentication

process the server veriﬁes the identity of the client attempting to connect to the

network. Unfamiliar clients would be denied access.

For home users that will not incorporate a RADIUS server in their network, the security

for the DI-524UP, used in conjunction with other 802.11g products, will still be much

stronger than ever before. Utilizing the Pre Shared Key mode of WPA, the DI-524UP

will obtain a new security key every time it connects to the 802.11g network. You only

need to input your encryption information once in the conﬁguration menu. No longer

will you have to manually input a new WEP key frequently to ensure security, with the

DI-524UP, you will automatically receive a new key every time you connect, vastly

increasing the safety of your communications.

Connections

All Ethernet Ports (WAN and LAN)

are auto MDI/MDIX, meaning you

can use either a straight-through or

a crossover Ethernet cable.

The Auto MDI/

MDIX WAN port is

the connection for

the Ethernet cable

to the Cable or

DSL modem

Auto MDI/MDIX

LAN ports

Features

WPA (Wi Fi Protected Access) authorizes and identiﬁes users based on a

secret key that changes automatically at a regular interval, for example:

802.1x Authentication in conjunction with the RADIUS server veriﬁes the

identity of would be clients



TKIP (Temporal Key Integrity Protocol), in conjunction with a RADIUS

server, changes the temporal key every 10,000 packets, ensuring

greater security

Pre Shared Key mode means that the home user, without a RADIUS

server, will obtain a new security key every time the he or she connects

to the network, vastly improving the safety of communications on the

network.

Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to-use and

compatible high-speed wireless connectivity within your home, business or public

access wireless networks. D-Link wireless products will allow you access to the data

you want, when and where you want it. You will be able to enjoy the freedom that

wireless networking brings.

A WLAN is a cellular computer network that transmits and receives data with radio signals

instead of wires. WLANs are used increasingly in both home and ofﬁce environments,

and public areas such as airports, coffee shops and universities. Innovative ways to

utilize WLAN technology are helping people to work and communicate more efﬁciently.

Increased mobility and the absence of cabling and other ﬁxed infrastructure have proven

to be beneﬁcial for many users.

Wireless users can use the same applications they use on a wired network. Wireless

adapter cards used on laptop and desktop systems support the same protocols as

Ethernet adapter cards.

People use wireless LAN technology for many different purposes:

Mobility - Productivity increases when people have access to data in any location

within the operating range of the WLAN. Management decisions based on real-time

information can signiﬁcantly improve worker efﬁciency.

Low Implementation Costs – WLANs are easy to set up, manage, change

and relocate. Networks that frequently change can beneﬁt from WLANs ease of

implementation. WLANs can operate in locations where installation of wiring may be

impractical.

Installation and Network Expansion - Installing a WLAN system can be fast and

easy and can eliminate the need to pull cable through walls and ceilings. Wireless

technology allows the network to go where wires cannot go - even outside the home

or ofﬁce.

Scalability – WLANs can be conﬁgured in a variety of topologies to meet the needs

of speciﬁc applications and installations. Conﬁgurations are easily changed and range

from peer-to-peer networks suitable for a small number of users to larger infrastructure

networks to accommodate hundreds or thousands of users, depending on the number

of wireless devices deployed.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Standards-Based Technology

The DI-524UP Wireless Broadband Router utilizes the new 802.11g standard.

The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the

data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.

This means that in most environments, within the speciﬁed range of this device, you

will be able to transfer large ﬁles quickly or even watch a movie in MPEG format over

your network without noticeable delays. This technology works by transmitting high-

speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division

Multiplexing) technology. OFDM works by splitting the radio signal into multiple

smaller sub-signals that are then transmitted simultaneously at different frequencies

to the receiver. OFDM reduces the amount of crosstalk (interference) in signal

transmissions.

The DI-524UP is backwards compatible with 802.11b devices. This means that if you

have an existing 802.11b network, the devices in that network will be compatible with

802.11g devices at speeds of up to 11Mbps in the 2.4GHz range.

Wireless Basics (continued)

Installation Considerations

The D-Link AirPlus G DI-524UP lets you access your network, using a wireless

connection, from virtually anywhere within its operating range. Keep in mind, however,

that the number, thickness and location of walls, ceilings, or other objects that the

wireless signals must pass through, may limit the range. Typical ranges vary depending

on the types of materials and background RF (radio frequency) noise in your home or

business. The key to maximizing wireless range is to follow these basic guidelines:

Keep the number of walls and ceilings between the DI-524UP and other

network devices to a minimum - each wall or ceiling can reduce your D-Link

wireless product’s range from 3-90 feet (1-30 meters.) Position your devices

so that the number of walls or ceilings is minimized.

Be aware of the direct line between network devices. A wall that is 1.5 feet

thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter)

thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position

devices so that the signal will travel straight through a wall or ceiling (instead

of at an angle) for better reception.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate extreme RF noise.

Building Materials can impede the wireless signal - a solid metal door or

aluminum studs may have a negative effect on range. Try to position wireless

devices and computers with wireless adapters so that the signal passes

through drywall or open doorways and not other materials.
