Introduction

*Not all servers can provide Authentication

The DWL-G630 has the newest, strongest and most advanced security

features available today. When used with other 802.11 WPA/WPA2 (Wi-Fi

Protected Access/Wi-Fi Protected Access 2TM) and 802.1X compatible

products in a network with a RADIUS server, the security features include:

WPA/WPA2: Wi-Fi Protected Access/Wi-Fi Protected Access 2TM

which authorizes and identifies users based on a secret key that

changes automatically at regular intervals. WPA/WPA2 uses TKIP

(Temporal Key Integrity Protocol) to change the temporal key every

10,000packets (a packet is a kind of message transmitted over a

network.) This ensures much greater security than the standard

WEP security. (By contrast, the previous WEP encryption

implementations required the keys to be changed manually.)

802.1X: Authentication which is a ﬁrst line of defense against intrusion. In

the authentication process, the Authentication 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 DWL-G630, used in conjunction with other WPA-

compatible 802.11 products, will still be much stronger than ever before.

Utilizing the Pre- Shared Key mode of WPA/WPA2, the DWL-G630 will

obtain a new security key every time it connects to the 802.11 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 DWL-G630, you will automatically receive a new key

every time you connect, vastly increasing the safety of your communication.

The D-Link AirPlus™ G DWL-G630 Wireless G Notebook Adapter is an

802.11b/802.11g high-performance, wireless adapter that supports high-

speed wireless networking at home, at work or in public places.

Unlike most network cards, the DWL-G630 provides data transfers at up to

54 Mbps (compared to the standard 11 Mbps) when used with other D-Link

AirPlus™ G products. The 802.11g standard is backwards compatible with

802.11b products.

products will automatically connect to the network out of the box.

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 wireless local area network (WLAN) is a computer network that transmits

and receives data with radio signals instead of wires. WLANs are used

increasingly in both home and ofﬁ ce 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 ﬁ xed infrastructure

have proven to be beneﬁ cial for many users.

Wireless Basics

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.

Wireless Basics (continued)

People use WLAN 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 signiﬁ cantly improve worker efﬁ ciency.

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

and relocate. Networks that frequently change can beneﬁ t 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 ofﬁ ce.

Inexpensive Solution - Wireless network devices are as competitively

priced as conventional Ethernet network devices.

Scalability - WLANs can be configured in a variety of ways 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.

Standards-Based Technology

The DWL-G630 Wireless G Notebook Adapter utilizes the 802.11b and

802.11g standards.

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 D-Link DWL-G630 will automatically sense the best

possible connection speed to ensure the greatest speed and range possible.

Wireless Basics (continued)

802.11g offers the most advanced network security features available today,

including: WPA/WPA2 , 802.1x, TKIP, AES and Pre-Shared Key mode.

The DWL-G630 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 up to 11Mbps in the 2.4GHz

range.

Installation Considerations

The D-Link AirPlus™ G DWL-G630 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 your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate RF noise.

Keep the number of walls and ceilings between the DWL-G630 and

other network devices to a minimum - each wall or ceiling can reduce

your DWL-G630 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.

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

Getting Started

Infrastructure - using an access point or wireless router

such as the DWL-7100AP, DI-624.
