Introducti on
The D-Link Air Xpert D WL-AG650 Tri-Mode Dualband Wireless Cardbus Adapter, when
installed into your desktop PC, pro vides you a versatile way to wirelessly connect to any
one of three available wireless networks - 802.11b and the newer, faster 802.11g and
802.11a that opera te in two discrete, non-interfering frequency bands, 2.4GHz and 5GHz.
The versa tile 802.11a/b/g compatible DWL-AG650 gives you an immediate way to expand
to your e xisting 802.11b network and protect your overall wireless network investment.
When you add an 802.11a/b/g access po int (D-Link Air Xpert DWL-7000AP) or router (DLink Air Xpert DI-774), your ne twork will be capable of handling up to four times the user
load of your current 802.11b netwo rk.
Along with compatibility to earlier 802.11b networks, the DWL-AG650 also offers t he
rob ust speed (up to 54Mbps) of the newer 802.11g and 802.11a standards, so that everyone
can work fa ster and more efficiently. Additionally, the 802.11a 5GHz band offers a way to
quick ly transfer data in a frequency range that does not experience interference or
interruptio ns from cordless phones, microwave ovens and other devices that use the 2.
4GHz frequency ba nd.
In a ddition to offering faster data transfer speeds when used with other 802.11a or draft
802.11g products, the DWL-AG650 has the newest, most advanced security features
available today, using the dr aft 802.11i security standard. These additional security
features are optiona l. You may choose to continue using the familiar WEP security, or
you may not wish to utilize se curity features at all. However, if you do choose to use the
D WL-AG650’s powerful security features with other WPA (WiFi Protected Access) and
802.1x compatible products in a network with a RADIUS server, the s ecurity features
will include:
WP A*: A ne w security feature, Wi-Fi Protected Access authorizes and identifies
users based on a secret key that changes automatically at a regular interval.
WP A 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 ensures much greater security than the standard WEP security. (By
contrast, the older WEP encryption require d the keys to be changed manually).
802.1x: Aut hentication is a first line of defense against intrusion. In the
Authentica tion process the server verifies the identity of the client attempting to
connect to the network. U nfamiliar clients would be denied access.
TM
Users that choo se not to incorporate a RADIUS server in their network may also use the
optional e nhanced security features, or they may wish to continue using the standard
WEP security, or they ma y choose to use no security at all. However, if you do wish to
experie nce the enhanced security of the DWL-AG650 in conjunction with other draft 802.
1 1i compatible products, without a RADIUS server, the Pre Shared Key mode of WPA
will assign a new se curity key every time the DWL-AG650 connects to the draft 802.11i
Acces s Point. If you choose to enable the enhanced security features of the DWLAG650, you need only to input your encryption information once in the configuration
menu. No longe r will you have to manually change the WEP key to ensure security - with
the DWL-AG650, you will automatically receive a new key every time you connect,
vastly increasing the safety of your communications.

Features
Dualband versatility - With the D WL-AG650, you have the option of using one
n
of two freque ncies. If the 2.4GHz frequency band is experiencing interruptions
and interfe rence from cordless phones, and microwave ovens, you have the option o f using the 5GHz band with 802.11a enabled devices.
Compatible with 802.11a, 802.11b and 802.11g Devices - Fully compatible
n
with the IEEE 802.11a , 802.11b and Draft 802.11g standards, the DWL-AG650
can connect with existing 802.11b routers, access points and cards. That means
you can still communicate with co lleagues and friends while you have the ability
to link to even more wireless ne tworks.
Better Security with 802.1x and WP A* -With the DWL-AG650 in your laptop
n
PC you can securely connect t o a wireless network using 802.1x for wireless
authentication, as well as WPA (Wi-Fi Protected Access) providing you a much
higher level o f security for your data and communications than has previously
bee n available. To use the DWL-AG650’s 802.1x security fea tures, your Operating System and all the de vices in your network must support it. Windows XP
suppo rts 802.1x and a free 802.1x upgrade is available for Windows 2000. Check
the manufacturer’s website for available 802.1x upgrades for other operating systems.
32-bit Ca rdbus Performance/Plug & Play Connectivity -The DWL-AG650 is

Wireles s Basics
D-Link wireless products are based on industry standards t o provide easy-touse 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 networ k that transmits and receives data with
radio signals instead of wires. WLANs are used increasingly in both hom e 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 sam e
protocols as Ethernet adapter cards.

Wireless B asics (continued)
People use WLAN technology for many different purposes:
Mobil ity - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions based
on real-tim e 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 im plementation. WLANs can operate in locations where the installation of
wiring may be impractical.
Installation a nd Network Expansion - Installing a WLAN system can be
fast and easy and can eliminate the need to pull cable through walls and ceilings.
Wireless t echnology allows the network to go where wires cannot go - even
outside the home or office.
Inexpensive Soluti on - Wireless network devices are as competitively
priced as conventional Ethernet network devices.
Scal ability - 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 netw orks to accommodate hundreds or thousands
of users, depending on the number of wireless devices deployed.
The DWL-AG650 is compatible with the following wireless products:
D-Link Air Xpert DWL-AG650, D-Link AirPro DWL-A650, D-Link

Standards-Ba sed Technology
The D WL-AG650 Wireless Cardbus Adapter utilizes the 802.11a, 802.11b and
draft 802.11g standard.
The IEEE draft 802.11g standard is an extension of the 802.11b standard. It
incr eases the data rate up to 54 Mbps within the 2.4GHz band. The 802.11a
standard also increases the data rate up to 54 Mbps, but within the 5GHz band.
Both 802.11a and 802.11g utilize 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. T he D-Link DWL-AG650 will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible.
The DWL-AG650 offers the most advanced network security features available
today, including: WPA and 802.1x.
In addition to its compatibility with 802.11g and 802.11a devices, the DWL-AG650
is compatible with 802.11b devices. This means that if you have an existing
802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b,
the devices in that network will be compatible with the DWL-AG650.

Installation Conside rations
The D-Link Air Xpert D WL-AG650 lets you access your network, using a wireless
TM
connection, from virtually anywhere within its operating range. Keep in mind,
however, t hat 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
frequency) noise in your home or business. The key to maximizing wireless
range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the DWL-AG650 and
other network devices to a m inimum - each wall or ceiling can reduce
your D-Link wir eless product’s range from 3-90 fee t (1-30 meters.) Position
your devices so that the number of walls or ceilings 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 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.
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 Star ted
There are basically two m odes of networking:
Infrastructure - using an Access Point or Wireless Router,
n
such as the D WL-7000AP or DI-774.
Ad-Hoc - directly connecting to another computer, for peer-to-
n
peer communication, using wireless network adapters on
each computer, such as two or m ore DWL-AG650 wireless
network Cardbus adapters.
On the following pages we will show you an example of an Infrastructure
Network and an Ad-Hoc Network.
An Infrastructure network contains an Access Point or a Wireless Router.

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 example: If the first computer is assigned an IP Address of 192.168.0.2
wit h a Subnet Mask of 255.255.255.0, then the second computer can be
assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.
0, etc.
IMPORTANT: If computers or other devi ces are assigned the same IP
Address, one or more of the devices may not be visible on the network.

Troubleshooting
2. I cannot connect to the Access Point or the wireless Router.
Make sure that the SSID on the DWL-AG650 Cardbus adapter is
n
exactly the same as the SSID on the Access Point or wireless
Router.
Move the DWL-AG650 and Access Point or wireless Router into
n
the same room and then test the wireless connection.
Disable all security settings. (WEP, MAC Address Control, AES)
n
Make sure that the Access Point/Router is not locked down to a
n
different frequency
Turn off your Access Point and the comput er with the
n
D WL-AG650. Turn on the Access Point, and then turn on the
computer with the D WL-AG650.
Refresh the DWL-AG650 Utility
n
3. The DWL- AG650 Power an d Li nk li ghts are not on.
n
Check to see if the DWL-AG650 Cardbus adapter is fir mly
inserted into the PC Card slot of your laptop computer.
4. I forgot my Encryption key.
Reset the Access Point to its factory default settings and restore the
n
DWL-AG650 Wireless Cardbus Adapt er to the factor y default
settings.
5. The computer does not recognize the DWL-AG650 Wireless Adapter.
Make sure that the D WL-AG650 Wireless Adapter is properly seated
n
in the com puter’s PC Card slot.
If Windows does not detect the hardware upon insertion of the
n
adapter, make sure to completely remove drivers that were
previously loaded. To remove the drivers, do the following:
35
Troubleshooting
A. Under Tools> select Folder O ptions… > select View >
under Hidden files and folders > select Show hidden
files and folders
B. Uncheck Hide extension for known file types > click
on A pply
C. Search for previously loaded driver files. Remove these
files from t he INF and SYSTEM32 (DRIVERS) folders
in the Windows directory. Note: Windows XP and
Windows 2000 will rename .inf files that have not
received WHQL cert ification into oem.inf files (e.g.,
oem1.inf).
6. The computer with the DWL-AG650 installed is unable to connect to
the wireless network and/or the Internet.
n
Check that the LED indicators for the broadband modem are
indicating normal activity. If not, there may be a problem with the
broadband connection.
Check that the LED indicators on the wireless router are functioning
n
properly. If not, check that the AC power and Ethernet cables are
firm ly connected.
Check that the IP Address, subnet mask, gateway, and DNS settings
n
are correctly entered for the network.
In Infrastructure mode, make sure the same Service Set
n
Identifier (SSID) is specified on the settings for the wireless clients
and access points. The SSID factory default setting for the D-Link
products is default. (Double-click on the WLAN icon in the taskbar.
The Link Info screen will display the SSID setting).
In Ad-Hoc m ode, both wireless clients will need to have the same
n
SSID. Please note that it might be necessary to set up one client to
establish a BSS (Basic Service Set) and wait briefly before setting
up other clients. This prevents several clients from trying to establish
a BSS at the same time, which can result in multiple singular BSSs
being established, rather than a single BSS with multiple clients
associated to it.
36
Troubleshooting
Check that t he Network Connection for the wireless client is
n
configured properly. Select AP (Infrastructure) when connecting
to an access point and select Ad-Hoc mode when connecting
without an access point. Double-click on the WLAN icon in the
taskbar > click on Configuration to change the settings for the
wir eless adapter.
n
If Security is enabled, m ake sure that the correct encryption keys
are entered on both the D WL-AG650 and the access point. Doubleclick on the WLAN icon in the taskbar > click Encryption. Check to
see that the key selected is set to the same key as other devices on
the network.
If Turbo mode is enabled, make sure that Turbo mode is enabled
n
on all T urbo mode compatible devices in your network, in order to
comm unicate.
7. How can I troubleshoot distance issues using the DWL-AG650.
Move the DWL-AG650 and Access Point or wireless Router into
n
the same room and then test the wireless connection.
Change the channel of the Access Point.
