3. Wireless Basics  
D-Link AirPlus 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 AirPlus 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 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  
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 Access  
Point (AP) is a device used to provide this link.  
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.  
 
Wireless Basics  
Network Expansion - Wireless technology allows the network to go where  
wires cannot go.  
Reduced Cost-of-Ownership - While the initial investment required for  
wireless LAN hardware might be higher than the cost of wired LAN hardware,  
overall installation expenses and life-cycle costs will be significantly lower.  
Long-term cost benefits are greatest in dynamic environments requiring  
frequent moves, adds, and changes.  
Scalability Wireless Local Area Networks (WLANs) can be configured in a  
variety of topologies 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 full infrastructure networks  
of thousands of users that allow roaming over a broad area.  
D-Link AirPlus Wireless Family of LAN products include:  
Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop  
computers (DWL-650+)  
Enhanced 2.4GHz Wireless PCI cards used with desktop computers  
(DWL-520+)  
Enhanced 2.4GHz Wireless Access Points (DWL-900AP+)  
Enhanced 2.4GHz Wireless Broadband Router (DI-614+)  
The DWL-900AP+ will also work with D-Link Air 802.11b wireless adapters,  
which include:  
2.4GHz Wireless Cardbus Adapters used with laptop computers  
(DWL-650)  
2.4GHz Wireless PCI cards used with desktop computers (DWL-520)  
Standards - Based Technology  
The IEEE standard-based technology assures that the D-Link AirPlus  
Products are interoperable with existing compatible 2.4GHz wireless  
technology. This means you will be able to transfer large files quickly or  
even watch a movie in MPEG format over your network without noticeable  
delays. The technology works by using multiple frequencies in the 2.4GHz  
range at speeds up to 22 Mbps. D-Link AirPlus products will automatically  
8
sense the best possible connection speed to ensure optimal network  
performance.  
Installation Considerations  
Designed to go up to 1,312 feet (400 meters) outdoors and up to 328 feet  
(100 meters) indoors, D-Link’s AirPlus DWL-900AP+ lets you access your  
network using a wireless connection from virtually anywhere. 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:  
1. Keep the number of walls and ceilings between the wireless Access  
Point and your receiving device (e.g., the DWL-650+) to a minimum -  
Each wall or ceiling can reduce your D-Link AirPlus Wireless product’s  
range from 3-90 feet (1-30 meters.) Position your Access Points,  
Residential Gateways, and computers so that the number of walls or  
ceilings is minimized.  
2. Be aware of the direct line between Access Points, Residential  
Gateways (routers) and computers. 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 the Access Points and adapters 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 Access Points,  
and computers with wireless adapters so that the signal passes through  
drywall or open doorways and not other materials.  
4. Make sure that the device’s antenna is positioned for best reception by  
using the software signal strength tools included with your product.  
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical  
devices or appliances that may generate extreme RF noise.  
For the average home, signal range should not be an issue. If you  
experience low or no signal strength in areas of your home that you wish to  
access, consider positioning the Access Point in a location directly between  
the computers with wireless adapters. Additional Access Points can be  
connected to provide better coverage in rooms where the signal does not  
appear as strong as desired.  
4. Getting Started  
Right out of the box, with its default settings, the DWL-900AP+ will  
automatically connect with other D-Link Air or AirPlus products.  
For the price of a single IP Address from your Broadband Internet Service  
provider you can share the Internet with all the computers on your local  
network, without sacrificing speed or security, using D-Link AirPlus  
networking products.  
IP ADDRESS  
Please note: If you have a DHCP-capable router, such as the D-  
Link DI-604 or DI-614+, there is no need to assign an IP Address.  
If you need to assign 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 with 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 devices are assigned the  
same IP Address, one or more of the devices may not be  
visible on the network.  
An Infrastructure network contains an Access Point. The Infrastructure  
Network example shown on the next page contains the following D-Link  
network devices:  
A wireless Access Point - D-Link AirPlus DWL-900AP+  
An Ethernet Broadband Router - D-Link DI-604  
A laptop computer with a wireless adapter - D-Link AirPlus DWL-650+  
A desktop computer with a wireless adapter - D-Link AirPlus DWL-520+  
A Cable modem - D-Link DCM-200  
DHCP stands for Dynamic Host Configuration Protocol.  
It is a protocol for assigning dynamic IP addresses “automatically.”  
With a DHCP-capable gateway/router, there is  
no need to manually assign an IP address.

Getting Started  
Setting Up an Infrastructure Network  
Please refer to the following sections  
of this manual for additional  
information about setting up a network:  
Networking Basics- learn how to  
check your IP Address; share printers  
and files.  
Using the Configuration Utility- learn  
the settings you must use on each  
computer in your network for  
successful communication.  
Troubleshooting- learn how to check  
for the proper installation of the  
network adapters’ drivers and other  
tips for troubleshooting the network.  
Please remember that D-Link AirPlus wireless devices are pre-configured to  
connect together, right out of the box, with the default settings.  
You will need a broadband Internet access (Cable/DSL)  
subscription.  
Consult with your Cable/DSL provider for proper installation of the  
modem.  
Connect the modem to an Ethernet Broadband Router (such as the  
D-Link DI-604) See the Quick Installation Guide included with the  
DI-604.  
Connect the router to the D-Link AirPlus DWL-900AP+. Refer to  
the Quick Installation Guide for setting up the DWL-900AP+.  
If you are connecting a desktop computer in your network, you can  
install the D-Link AirPlus DWL-520+ wireless PCI adapter into an  
available PCI slot. See the Quick Installation Guide included with the  
DWL-520+.  
Install the drivers for the wireless cardbus adapter (D-Link  
AirPlus DWL-650+) into the laptop computer. See the Quick  
Installation Guide included with the DWL-650+ for installation  
instructions.  
5. Using the Configuration Menu  
The Configuration Menu for the DWL-900AP+ is web-based. When using  
the configuration program, please consider the following:  
You will need a JavaScript-enabled web-browser such as Internet Explorer  
4.0 or higher, or Netscape Navigator 4.0 or higher.  
The computer that you are using for initial configuration must have an IP  
Address within the same range as the IP Address of the DWL-900AP+.  
The DWL-900AP+ has a default IP Address of 192.168.0.50 with subnet  
mask of 255.255.255.0  
If you are using a D-Link router in your network, such as the DI-604, with the  
factory default settings, you will not need to assign a static IP Address to the  
computer that you are using to configure the Access Point. (Skip to Fig. 5.1:  
entering the IP address)  
If you are not using a D-Link router in your network, you will need to assign a  
Static IP Address to the computer that you are using to configure the DWL-  
900AP+, within the IP Address Range of the DWL-900AP+. Assign a static IP  
address of 192.168.0.2 with subnet mask of 255.255.255.0 (Please see  
Networking Basics in this manual for information on Assigning a Static IP  
Address.)  
Note: Please write down the current IP address settings of the computer. You  
may need to revert back to these settings after configuring the DWL-900AP+.  
After you have assigned a Static IP Address to the computer you are using for  
configuration (if necessary), next you will assign the DWL-900AP+ an IP  
Address within the range of your existing network.  
After changing the DWL-900AP+’s IP Address, you must revert back to the  
original IP address in order to regain connection to the DWL-900AP+.  
If the computer had a static IP address, re-input that same address.  
If the computer had a dynamic IP Address (i.e., a DHCP capable router  
automatically assigns the IP Address) then change the setting of your  
network adapter to receive a Dynamic IP Address.

7.Troubleshooting  
This chapter provides solutions to problems that can occur during the  
installation and operation of the DWL-900AP+ Wireless Access Point. We  
cover various aspects of the network setup, including the network adapters.  
Please read the following if you are having problems.  
Note: It is recommended that you use an Ethernet connection to  
configure the DWL-900AP+ Access Point.  
1. The computer used to configure the DWL-900AP+ cannot access the  
Configuration menu.  
Check that the Ethernet LED on the DWL-900AP+ 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-900AP+. Please see Checking the IP Address  
in Windows XP in the Networking Basics section of this  
manual.  
Note: The IP Address of the DWL-900AP+ 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-900AP+ is  
responding. Go to Start>Run>Type Command>Type ping  
192.168.0.50. A successful ping will show four replies.  
 
Troubleshooting  
2. The wireless client cannot access the Internet in the Infrastructure  
mode.  
Make sure the wireless client is associated and joined with the correct  
Access Point. To check this connection: Right-click on the Local  
Area Connection icon in the taskbar> select View Available  
Wireless Networks. The Connect to Wireless Network screen will  
appear. Please make sure you have selected the correct available  
network, as shown in the illustrations below.  
Default  
Check that the IP Address assigned to the wireless adapter is within  
the same IP Address range as the access point and gateway. Since  
the DWL-900AP+ has an IP Address of 192.168.0.50, wireless  
adapters must have an IP Address in the same range, e.g.,  
192.168.0.x. Each device must have a unique IP Address; no two  
devices may have the same IP Address. The subnet mask must be  
the same for all the computers on the network.) To check the IP  
Address assigned to the wireless adapter, double-click on the  
Local Area Connection icon in the taskbar > select the Support  
tab and the IP Address will be displayed. (Please refer to Checking  
the IP Address in the Networking Basics section of this manual.)  
If it is necessary to assign a Static IP Address to the wireless  
adapter, please refer to the appropriate section in Networking  
Basics. If you are entering a DNS Server address you must also  
enter the Default Gateway Address. (Remember that if you have a  
DHCP-capable router, you will not need to assign a Static IP Address.  
See Networking Basics: Assigning a Static IP Address.)

Troubleshooting  
4. Resetting the DWL-900AP+ to Factory Default Settings  
After you have tried other methods for troubleshooting your network, you  
may choose to Reset the DWL-900AP+ to the factory default settings.  
Remember that D-Link AirPlus products network together, out of the box,  
at the factory default settings.  
To hard-reset the D-Link AirPlus DWL-900AP+ to Factory Default Settings,  
please do the following:  
Locate the Reset button on the back of the DWL-900AP+  
Use a paper clip to press the Reset button.  
Hold for about 5 seconds and then release  
After the DWL-900AP+ reboots (this may take a few minutes) it will  
be reset to the factory Default settings.
