6 Wireless Basics D-Linkwireless 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 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.
7 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 â€“ 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 â€“ 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.
8 Wireless Basics (continued) The DWL-1000AP+ is compatible with the following D-LinkAirPro multi-mode wireless network adapters:
â™¦ 2.4GHz multimode Wireless Cardbus Adapter used with laptop
â™¦ 2.4GHz Wireless PCI card used with desktop computers
(DWL-AB520) 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 wireless network is more impervious to intruders than has previously been possible.
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 allows you to select the type of EAP you wish to use. 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.
If you are not using Windows XP, you can purchase EAP software to install for the wireless clients in your network.
The second level of security in the 802.1x 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 secure networking by automatically changing WEP keys periodically, thus relieving administrators of the onerous task of manually changing keys on a multitude of workstations.
9 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 productâ€™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.
10 Getting Started
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 to keep the ethernet cable connection between the access points. An ethernet
connection is needed so that IAPP (Inter Access Point Protocol) can be used to enable
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 effective wireless net-
work than you have previously experienced.
Using the Configuration Menu
Before you use the configuration utility for the DWL-1000AP+, you must install the driv-
ers and the configuration utilityby inserting the CD-ROM that came with the DWL-
1000AP+. (Please see the Quick Installation Guide that came with the product.) After
you have completed this installation and restarted your computer, you can access the
Configuration Utility at any time by clicking on the icon in your taskbar at the bottom
right corner of your PCâ€™s screen.
After double-clicking on the icon in the taskbar (shown at right), the
following Configuration Utility window will appear:
If you choose to use the configuration menu, please configure the DWL-1000AP+ from
a computer with an ethernet connection to the DWL-1000AP+. Home > Wizard
Clicking Apply will save changes made to the page Apply
Clicking Cancel will clear changes made to the page Cancel
Clicking Help will bring up helpful information regarding the page Help
Clicking Restart will restart the router. (Necessary for some changes.) Restart
12 Using the Configuration Menu Home > Wireless 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) â€śdefaultâ€ť 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 â€śload balancingâ€ť network should set their channel to â€śauto.â€ť) 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 â€“ 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. 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
13 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. (This
choice may make configuring your network and the DWL-1000AP+ more difficult than
if you used a Static IP Address, depending on the function of the DWL-1000AP+ in your network.) DHCP stands for Dynamic Host Configuration Protocol. It is a protocol for assign-
ing dynamic IP addresses â€śautomatically.â€ť With a DHCP-capable gateway/router,
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+â€™s in your network (for Load Balancing or Backup), you
will need to assign a different Static IP Address to each Access Point. Please refer to
the Troubleshooting section for more information on assigning an IP Address. 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 or switch, if you have one 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.
14 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 DHCP Client Table: Lists the devices on your network that are receiving dynamic IP Addresses from the Access Point
15 Using the Configuration Menu Advanced > Mode Access Point: The Access Point is selected as the default setting. This must be selected to use Load Balancing Mode and Backup Mode. Load Balancing: Connect 3 DWL-1000AP+â€™s with ethernet cable to share the wireless
network traffic. We recommend that you connect no more than 3 DWL-1000AP+â€™s
because there are 3 non-overlapping channels. 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). For optimal performance, you may wish to overlap the areas of coverage of each access point to facilitate roaming. Backup AP: Connect 2 DWL-1000AP+s with Ethernet cable and also connect each
Access Point to a separate port on the switch. 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 APâ€™s MAC Address into the secondary APâ€™s configuration window. To use the Keep Alive Connection, enter the IP address of a radius server or switch on your
network. The Keep Alive Connection will monitor the connection to the Ethernet network
and send a warning to the log to notify the administrator of any connectivity problems with the LAN (Local Area Network or Ethernet 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 Multi-point Bridge: Select this option to use the DWL-1000AP+ as a mult-point bridge. In this mode it will associate with any available bridge 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
16 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 network.
Specify a Beacon interval value.
Default (100) is recommended. RTS Threshold: This value should
remain at its default setting of 2,432. If you encounter inconsistent data flow,
only minor modifications to the value range between 256 and 2,432 are recom-
mended. 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. 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
17 SSID Broadcast: (Service Set Identifier) Enable or Disable (default) the
broadcast of the SSID name across the network. SSID is a name that
identifies a wireless network. All devices on a network must use the same
SSID to establish communication. Client Security: Disabled is the default setting. Enabling this setting ensures
that the wireless clients will be secure and their files and folders will not be
available to other wireless clients Antenna selection: Choose Left, Right or Diversity. Diversity is the default
selection. By choosing which antenna is active, you can more selectively
configure your network. Antenna transmit power: Default is the default setting. Select the range you
desire for your AP transmission. If you do not want the signal to range too far,
you can limit the distance with this tool. This may be helpful in securing your
network. Using the Configuration Menu Advanced> Filters
Use MAC Filters to allow or deny computers by their MAC addresses from access-
ing the DWL-1000AP+. You can either manually add a MAC address or select the
MAC address from the list of clients that are currently connected to the Broadband

Encryption Key: Select the key length, either 64 bits or 128 bits. Lifetime: Select 5, 15, 30 minutes, or 1or 8 hours, or 1 day for the authentication period. After this period expires, members of the network will have to re-logon to gain access to the network. Radius Server 1 IP: Enter the IP Address of the Radius Server Port: Enter the port number that your Radius Server uses for Authentication. The default setting of 1812 is the port setting for many Radius Servers Shared Secret: Enter the Shared Secret. The shared secret must be the same as the shared secret on your radius server. Radius Server 2: Optional. If you have a second radius server, you will input the same information as shown above.
19 Using the Configuration Menu Tools > Admin SNMP (Simple Network Management Protocol) is a widely used network monitoring and
control protocol. The DWL-1000AP+ supports SNMP V1. SNMP allows one computer
on the network (the administrator) to monitor the devices on the network and to perform
some management functions. You will need to providea software program (e.g., MIB Browser or HP Openview) to implement SNMP. The DWL-1000AP+ provides the plat-
form to utilize this internet network management program to monitor and control your
network. New Password: Enter the new password Confirm Password: Re-enter the password to confirm it Enabled is the default selection. Select Disabled to disable it.

24 Using the Configuration Menu Help
Select from the menu above for extra help.
This chapter provides solutions to problems that can occur during the installa- tion and operation of the DWL-1000AP+. We cover various aspects of the network including network adapters. (The examples below are illustrated in Windows XP. If you have another operating system, these solutions will still apply although the appearance on your computer screen may differ.) Note: It is recommended that you use an Ethernet connection to configure the DWL-1000AP+ Access Point. 1. The computer used to configure the DWL-1000AP+ cannot access the Configuration menu.
Check that the Ethernet LED on the DWL-1000AP+ is ON. If
the LED is not ON, check that the cable for the Ethernet connection is securely inserted.
Check that the Ethernet Adapter is working properly. Please see item 3 (Check that the drivers for the network adapters are installed properly) in this Troubleshooting section to check that the drivers are loaded properly.
Check that the IP Address is in the same range and subnet as the DWL-1000AP+. Please see Checking the IP Addressin Windows XP in the Networking Basics section of this manual. Note: The IP Address of the DWL-1000AP+ is 192.168.0.50. All the computers on the network must have a unique IP Address in the same range, e.g., 192.168.0.x. Any computers that have identical IP Addresses will not be visible on the network. They must all have the same subnet mask, e.g., 255.255.255.0
Do a Ping test to make sure that the DWL-1000AP+ is responding. Go to Start>Run>Type Command>Type ping 192.168.0.50. A successful ping will show four replies.
