Introduction
The D-Link AirPremier DWL-1000AP+ Wireless Access Point is an 802.1x
high-performance wireless access point. With a second level of security that
is not offered with other conventional 802.11 standards-compatible Access
Points, the DWL-1000AP+ ensures a more secure wireless network than ever
before. In addition to WEP encryption, the DWL-1000AP+ offers an
Authentication capability when used with 802.1x compatible devices. This
extra layer of protection will ensure a safer and more secure wireless network
than has previously been available.
Outstanding features of the DWL-1000AP+ include Backup AP Function,
Load-Balancing, and Dynamic Channel Selection Function. Please see
the Features and Benefits section in this manual for further details on these
special features.
Speed is another unique feature of the DWL-1000AP+. Unlike most access
points, the DWL-1000AP+ is capable of data transfer speeds of up to 22 Mbps
(compared to the standard 11 Mbps) when used with D-Link AirPlus products
such as the DWL-520+ Wireless PCI Adapter and DWL-650+ Wireless Cardbus
Adapter.
After completing the steps outlined in the Quick Installation Guide (included in
your package) you will have the ability to share information and resources,
such as files and printers, and enjoy the freedom that wireless networking
delivers.
The DWL-1000AP+ is compatible with most popular operating systems,
including Macintosh, Linux and Windows, and in conjunction with a radius server,
can be integrated into a large enterprise network. This Manual is designed to
help you connect the Access Point and D-Link Adapters into a network in
Infrastructure mode. Please take a look at the Getting Started section in this
manual to see an example of an Infrastructure network using the DWL-1000AP+.
This manual provides a quick introduction to wireless technology and its
application as it relates to networking.

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. Strictly adhering to the IEEE standard, the
D-Link wireless family of products will allow you to securely access the data
you want, when and where you want it. You will be able to enjoy the freedom
that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless LANs
are used increasingly in both home and office environments, and public areas
such as airports, coffee shops and universities. Innovative waysto 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 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.
Under many circumstances, it may be desirable for mobile network devices to
link to a conventional Ethernet LAN in order to use servers, printers or an Internet
connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.

Wireless Basics (continued)
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 (Wireless Local Area Networks) are
easy to set up, manage, change and 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 impractical.
Installation Speed and Simplicity - Installing a wireless LAN system can
be fast and easy and can eliminate the need to pull cable through walls and
ceilings.
Network Expansion - Wireless technology allows the network to go
where wires cannot.
Scalability – Wireless Local Area Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications or existing
infrastructures. 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.

The DWL-1000AP+ is compatible with the following D-Link AirPro dual-band
wireless network adapters:
2.4GHz multimode Wireless Cardbus Adapter used with laptop
computers (DWL-AB650)
2.4GHz Wireless PCI card used with desktop computers
(DWL-AB520)
The DWL-1000AP+ is also compatible with the following D-Link AirPlus
wireless network adapters:
Standards-Based Technology
The versatile DWL-1000AP+ Wireless Access Point is 802.1x compatible.
The 802.1x standard solves the problem of ensuring the safety of wireless
networks by allowing for an additional layer of security. With two levels of
security, Authentication and Data Encryption, the 802.1x enhanced wireless
network is more inaccessible to intruders than has previously been possible.
Wireless Basics (continued)
The Authentication protocol in 802.1x provides the frontline of defense against
network intrusion. EAP (Extensible Authentication Protocol) is the protocol used
for authentication. Windows XP currently supports EAP. All the clients, access
points, and servers must share the same type of EAP in order to communicate
and ensure that the network is secure.
You can also purchase EAP software to install 802.1x support for the wireless
clients in your network.
The second level of security for the wireless network is WEP data encryption.
Depending on the radius server deployed in your network, you can distribute
the certificate automatically and change Encryption keys in the wireless network.
This network feature will greatly reduce the amount of time needed to ensure
wireless security by automatically changing WEP keys periodically, thus relieving
administrators of the onerous task of manually changing keys on a multitude of
workstations.

Wireless Basics (continued)
Installation Considerations
Keep in mind 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:
1. Keep the number of walls and ceilings between the DWL-1000AP+ 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.
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! Try to make sure that devices are positioned so that the signal will
travel straight through a wall or ceiling for better reception.
3. Building Materials make a difference - 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 generate RF noise.

Here is a sample of a network setup using the 802.1x compliant DWL-1000AP+
access point. Your network may look different. For successful communication,
you will need 802.1x compliant devices, including 802.1x compliant wireless
network adapters. If you are using two or more access points in conjunction for
load-balancing or backup, please remember that IAPP (Inter Access Point
Protocol) is passed through the Ethernet connection.
Please read through the configuration section of this manual to learn about the
settings you will need for your devices to achieve a faster, safer and more effec-
tive wireless network than you have previously experienced.

AP Name: You may choose to rename your Access Point, especially if you have
more than one Access Point on your network.
SSID: (Service Set Identifier)default is the default setting. The SSID is a unique
name that identifies a network. All devices on a network must share the same SSID
name in order to communicate on the network. If you choose to change the SSID from
the default setting, input your new SSID name in this field. The SSID can be up to 32
characters in length.
Channel: Channel 6 is the default channel. Input a new number if you want to change
the default setting. All devices on the network must be set to the same channel to
communicate on the network. (However, if are employing the Load Balancing function of
the AP, you will need to set each AP to a different non-overlapping channel: 1, 6 or 11.
Clients in a “load balancing” network should set their channel to “auto.”)
WEP Encryption: Select Enable Encryption to use WEP (Wired Equivalent Privacy)
on the network. All devices on the network, and the Access Point, must share the same
WEP selection – either Enable or Disable, and they must share the same WEP key.
The WEP key is generated from ASCII or Hexadecimal entries that are either 64, 128,
or 256 bit in length. When enabling encryption, select the Key Type (ASCII or
Hexadecimal) and then input the appropriate digits or letters. You can create up to 4
keys. Select the key you wish to use.
Using the Configuration Menu
Home > Wireless
Hexadecimal digits consist of the numbers 0-9 and the letters A-F
ASCII (American Standard Code for Information Interchange) is a code for
representing English letters as numbers from 0-127
Dynamic Channel Selection Function: automatically selects the fastest and
least populated channel available for the DWL-1000AP+ when it is a part of a Load
Balancing Group of 4 or more Access Points, when the 3 non-overlapping channels
have already been selected.

Using the Configuration Menu
Home > LAN
Dynamic IP Address: Select this option if you would like to have an IP Address
automatically assigned to the DWL-1000AP+ by a DHCP server in your network.
IP Address
If you need to assign Static IP Addresses to the devices in your network, please
remember that the IP Address for each computer or device must be in the same IP
Address range as all the devices in the network. Each device must also have the
same Subnet Mask. For example: Assign the first computer an IP Address of
192.168.0.2 and a Subnet Mask of 255.255.255.0, the second device an IP Ad-
dress of 192.168.0.3 and a Subnet Mask of 255.255.255.0, and so on. Devices that
are assigned the same IP Address may not be visible on the network.
DHCP stands for Dynamic Host Configuration Protocol. It is a protocol for assign-
ing dynamic IP addresses “automatically.” With a DHCP Server there is no need to
manually assign an IP address.
Static IP Address: Select this option if you are manually assigning an IP Address.
IP Address: 192.168.0.50 is the default IP Address of the Access Point. If you are
using several DWL-1000AP+’s in your network (for Load Balancing or Backup), you
will need to assign a different Static IP Address to each Access Point.
Subnet Mask: 255.255.255.0 is the default Subnet Mask. All devices on the
network must have the same subnet mask to communicate on the network
Gateway: Enter the IP Address of the gateway in your network

15
Using the Configuration Menu
Home > DHCP
DHCP Server: Select Enabled or Disabled. Disabled is the default setting. If
you want to use the Access Point as a DHCP server to automatically assign Dynamic
IP Addresses on the network, you will select Enabled.
Starting IP Address: If you have enabled the DHCP server function, enter the
starting point of the IP Address range for your network
Ending IP Address: Enter the ending IP Address of your IP Address range, if you
have enabled the DHCP function of the Access Point
Lease Time: Choose the length of time at which the DHCP function of the DWL-
1000AP+ automatically regenerates the IP Addresses to the devices in your network

IP Addresses from the Access Point

16
Using the Configuration Menu
Advanced > Mode
Load Balancing: Allow several DWL-1000AP+’s with the same group name to share
the wireless network traffic. We recommend an optimal number of three DWL-1000AP+’s
in close proximity because there are 3 non-overlapping channels (as specified by the
802.11b standard.) After selecting this option, you will be prompted to enter a Group
Name. All the APs that share Load Balancing must have the same Group Name and
the same SSID. Assign each Access Point a different non-overlapping channel (e.g.,
1, 6, 11).
Backup AP: Connect 2 DWL-1000AP+s with an Ethernet cable. One of the APs will
be the Primary AP, the other AP will backup the primary AP in the event of a primary AP
failure. Enter the Primary AP’s MAC Address into the secondary AP’s configuration
window. To use the Keep Alive Connection, enter the IP address of a radius server or
router on your network. The Keep Alive Connection will monitor the connection to the
Ethernet network and send a notification to the administrator of any connectivity problems
with the LAN (Local Area Network) connection.
Wireless Client: Make this selection to use the DWL-1000AP+ as a wireless
client instead of as an Access Point; you will enter the MAC address of the remote
AP to which the DWL-1000AP+ will be a client.
Wireless Bridge: To use the DWL-1000AP+ as a wireless bridge you will enter
the MAC address of the remote bridge to which the AP will associate.
Repeater: To extend the range of the wireless network select this option and enter
the MAC address of the remote AP within your network that will have its range
extended. Please note that the DWL-1000AP+ is able to repeat the wireless signal
from another DWL-1000AP+, DWL-900AP+, DI-614+, DI-764, and DI-754 with a DWL-
650+.
Multi-point Bridge: Select this option to use the DWL-1000AP+ as a mult-point
bridge. In this mode it will associate with remote bridges.
Access Point: The Access Point is
selected as the default setting. This must
be selected to use Load Balancing
Mode and Backup Mode.

Using the Configuration Menu
Advanced > Performance
The default Performance settings
are shown here.
Beacon Interval: Beacons are
packets sent by an Access Point
to synchronize a wireless net-
work. Specify a Beacon interval
value. Default (100) is recom-
mended.
RTS Threshold: This value
should remain at its default setting
of 2,432. If you encounter incon-
sistent data flow, only minor
modifications to the value range
between 256 and 2,432 are
recommended.
Fragmentation: This value should remain at its default setting of 2,346. If you
experience a high packet error rate, you may slightly increase your Fragmenta-
tion Threshold within the value range of 256 to 2,346. Setting the Fragmenta-
tion Threshold too low may result in poor performance.
DTIM Interval (Beacon Rate): (Delivery Traffic Indication Message) Enter a
value between 1 and 255 (default is 3) for the Delivery Traffic Indication Mes-
sage (DTIM.) A DTIM is a countdown informing clients of the next window for
listening to broadcast and multicast messages.
Basic Rates: Default is 1-2Mbps. We recommend that you keep the setting at
default. If you lose connection at the TX rate, you will regain connection at the
basic rate. A lower Basic Rate will make reconnection easier. (If you are run-
ning a wireless network consisting of all D-Link AirPlus and AirPremier prod-
ucts, you may set a higher basic rate.)
TX Rates: Select the transmission rate for the network. The default rate is 1-
2-5.5-11-22Mbps.
Preamble: Long Preamble is the default setting. (High traffic networks should
use the shorter preamble type.) The preamble defines the length of the CRC
block (Cyclic Redundancy Check is a common technique for detecting data
transmission errors) used in communication between the Access Point and the
roaming wireless Network adapters.
Authentication:
Open System - communicates the key across the network
Shared Key - devices must have identical WEP settings to communicate
Auto - automatically adjusts to the Authentication mode of the wireless client

18
Using the Configuration Menu
