Introduction

The D-Link AirPlus Xtreme G+ DWL-G650+ Wireless Cardbus Adapter is a 802.11g high- performance, wireless adapter that supports high-speed wireless networking at home, at work or in public places.

U nlike most network cards, the DWL-G650+ provides data transfers at up to 8X (compared to the st andard 11 Mbps) when used with other D-Link AirPlus Xt reme G products. The

802.1 1g 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 los e the abilit y to communicate when you incorporate the 802.11g standard into y our

802.1 1b network. You may choose to slowly change your network by gradually replacing the 802.11b devices with 802.11g devices .

In addition to offering fa ster data transfer speeds when used with other 802.11g products, the DWL-G650+ has the newest, strongest, most advanced security feat ures available today. When us ed with other 802.11g WPA (WiFi P rotect ed Access) and 802.1x compatibl e products in a network with a radius server, the security features include:

WPA*: A new s ecurity feature, 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 muc h greater securit y t han the standard WEP securit y. (By contra st, the older WEP encryption required the keys to be cha nged manually.)

802.1x*: Authentication is a firs t line of defense against intrusion. In the Authentication proces s the server verifies the identity of the client attempting to connect t o the network. Unfamiliar clients would be denied a ccess.

For home users that will not incorporate a RADIUS server in their network, the security for the D WL-G650+, used in conjunction with other 802.11g products, will still be much stronger tha n ever before. Utilizing the Pre Shared Key mode of WPA, the DWL-G650+ will obt ain a new security key every time it connec ts to the 802.11g network. You only need to input your encryption information once in the configuration menu. No longer will you have to ma nually input a new WEP key frequently to ensure se curity, with the DWLG650+, you will a utomatically receive a new key every time you connect, vastly increasing the safet y of your communications.

Wireless B asics

D-Link wireless products are based on industry standards to provide easy-to- use a nd compatible high-speed wireless connectivity within your home, business or public access wireless networks. D-Link wireles s products will allow you a ccess to the data you want, when a nd where you w ant it. You will be able to enjoy the freedom that wireless networking brings.

A WLAN is a c ellular computer network that transmits and receives data with radio signals instead of wires. WLANs are used increasingly in both home a nd office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN tec hnology are helping people to work a nd communicate more efficiently. Increased mobility a nd the absence of cabling and other fixed infrastruc ture have proven to be beneficial for many users.

Wireless users c an 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

locatio n within the operating range of the WLAN. Management decisions based on real-time information c an significa ntly improve worker efficiency.

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

a nd relocate. Networks that frequently change, both physically and logically, can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impra ctical.

Installation and Network Expansion - Installing a WLAN system ca n be

fa st 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.

Inexpensive Solution – Wireless network devices are as competitively priced

a s conventional Ethernet network devices.

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

of specific applications a nd installations. Configurations are easily cha nged a nd range from peer-to-peer networks suitable for a small number of users to larg er infrastructure networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed.

Standards-Based Technology

The DWL-G650+ Wireless Cardbus Adapter utilizes the 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 mea ns that in most environments, within the sp ecified range of this device,

you w ill 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 tra nsmittin g high-speed digital data over a radio wave utilizing OFDM (Ort hogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at diffe rent frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions. The D-Link DWL-G650+ will automati cally sens e the best possible connection speed to ensure the greatest speed and ra nge possible.

802.11g offers the most advanced network security features available today, includ ing: WPA , 802.1x TKIP, AES and Pre-Shared Key mode. These security

features are explained in more detail in the Introd uction and the Features section of this manual.

The DWL-G650+ 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. Als o based on the IEEE 802.11b sta ndard, the DWL-G650+ is interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps.

Installation Considerations

The D-Link AirPlus Xtreme G+ DWL-G650+ 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. T ypical ranges vary depending on the types of materials and background RF (radio frequenc y) noise in your home or business . The key to maximizing wireless ra nge is to follow these basic guidelines:

1. Keep the number of walls and ceilings between the DWL-G650+ and

other network devices to a minimum - each wall or ceiling can reduce your D-Link AirPlus Extreme G+ Wireless product’s ra nge from 3-90 feet (1-

30 meters.) Position your devices so that the number of walls or c eilings is

minimized.

2. 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.

3. Building Materials ca n impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on ra nge. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that may generate extreme RF noise.

Getting Started

There are basically two modes of networking:

Infra structure – using an Access Point, or Wireless Router,

such a s the DI-624+.

Ad-Hoc – directly connecting to another computer, for peer-to-

peer communication, using wireless network ada pters on ea ch computer, such a s two or more DWL-G650+ wireless network Cardbus adapters.

On the following pages we will show you an example of a n Infrastructure Network and an Ad-Hoc Network.

An Infra structure network c ontains an Access Point or a Wireles s Router. The Infra structure Network example shown on the following page contains the following D-Link network devices (your existing network may be comprised of other devices):

A wireless Router - D-Link AirPlus Xtreme G+ DI-624+

A la ptop computer with a wireles s adapter -

D-Link AirPlus Xtreme G+ DWL-G650+

A desktop c omputer with a wireles s adapter -

D-Link AirPlus Xtreme G DWL-G520+,

or D-Link AirPlus DWL-520+ A Cable modem - D-Link DCM-200

Getting Started

Setting up a Wirele ss Infrastructure Network

Plea se remember that D-Link AirPlus Xtreme G+ wireless devices are pre- configured to connect together, right out of the box, w ith their default settings.

For a ty pical wireless setup at home (as shown above), please do the following:

You will need broadba nd Internet access (a Cable or DSL-subscriber line into

your home or office)

Consult with your Cable or DSL provider for proper installation of the modem

Connect the Cable or DSL modem to your broadba nd router (see the Quick Installation Guide included w ith your router.)

If you are connecting a desktop computer to your network, install the D-Link

AirPlus Xtrem G+ D WL-520+ wireless PCI adapter into an available PCI slot on

your desktop computer . You may also install the D WL-520+.

(See the Quick Installation Guide included with the network adapter.)

Install the drivers for the D-Link D WL-G650+ wireless Cardbus adapter into a la ptop computer. You may also install DWL-650+. (See the Quick Installation Guide included with the network adapter.)

Getting Started

Setting up a Wireless Ad Hoc Network

I nstall the D-Link DWL-G650+ Wireless Network adapter into one la ptop computer. See t he Quick Installation Guide included w ith the

product for installation instructions.

I nstall another DWL-G650+ into a laptop computer. See the Quick

Ins tallation Guide included w ith the product.

Set the wireless configuration for the adapters to Ad-Hoc mode, set the ada pters to the same channel, and assign an IP Address to ea ch computer on the Ad-Hoc network. (See Box below)

IP Address

When assigning IP Addresses to the computers on the network, please remember that the IP Address for each computer must be in the same IP Address range as all the computers in the network, and the subnet mask must be exactly the same for all the computers in the network.

For exa mple: If the first computer is assigned an IP Address of 192.168.0.2 with a Subnet M ask of 255.255.255.0, then the second computer can be a ssigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255. 0, etc.

IMPORTANT: If computers or other devices are assigned the same IP Add ress, one or m ore of the devices may not be visible on the network.

Using the Configuration Utility

I f you wish to change the default settings or optimize the performa nce of the DWL-G650+, D-Link has included a configuration utility for this purpose. However, in Windows XP, you will instead use zero configuration utility.

Before you use the configuration utility for the DWL-G650+, you must install the drivers a nd the configuration utility from the CD-ROM that came with the DWL- G650+. (Plea se see the Quick Installation Guide that came with the product.) After yo u have completed this installation and restarted your computer, you can a ccess the Configuration Utility at a ny time by clicking on this icon that will a ppear on your desktop.
