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.
 8 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
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.
 10 4. Getting Started  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 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. 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 thenetwork, please remember that the IP Address for eachcomputer must be in the same IP Address range as all thecomputers in the network, and the Subnet mask must be exactlythe same for all the computers in the network.   For example:  If the first computer is assigned an IP Address of192.168.0.2 with a Subnet Mask of 255.255.255.0, then the secondcomputer can be assigned an IP Address of 192.168.0.3 with aSubnet Mask of 255.255.255.0, etc.   IMPORTANT: If computers or other devices are assigned thesame IP Address, one or more of the devices may not bevisible on the network. Right out of the box, with its default settings, the DWL-900AP+ will automatically connect with other D-Link Air or AirPlus products.
Getting Started Setting Up an Infrastructure 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+. 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- learnthe settings you must use on each computer in your network for successful communication. Troubleshooting-  learn how to checkfor the proper installation of thenetwork adapters’ drivers and othertips for troubleshooting the network.  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.
 12 5.  Using the Configuration Menu The Configuration Menu for the DWL-900AP+ is web-based.  When using the configuration program, please consider the following:   Factory Default Settings for the DWL-900AP+ SSID default Channel 6 Encryption disabled User Name  admin Password  (no password, leave field blank) IP Address  192.168.0.50 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.
Using the Configuration Menu  Whenever you want to configure your network or the DWL-900AP+, you can access the Configuration Utility by opening the web-browser and typing in the IP Address of the DWL-900AP+.  The DWL-900AP+’s default IP Address is shown below:   (The IP Address shown in the example above is the default setting.  Use this IP address when connecting to a network consisting of other D-Link devices set to their default settings.  If you have changed the IP Address of the DWL-900AP+ to conform to a network other than one with D-Link devices, then input that IP Address in the web browser, instead of the default IP Address shown.)                                                    Fig. 5.2                        Fig. 5.3    •  Open the web browser •  Type in the IP Address of the Access Point •  Type admin in the User Name field  •  Leave the Password blank  •  Click OK  Fig. 5.1 The Configuration window will appear.

 14 Using the Configuration Menu  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. 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.      Click Help at any time for more information. Click Apply if you have made any changes or additions. This window displays the default settings of the DWL-900AP+.    The default IP Address is 192.168.0.50.  If you select Dynamic IP Address, you will obtain a dynamic IP Address from a DHCP server on your network.  (This is not advisable since it will be difficult to determine the dynamic IP address assigned to the DWL-900AP+.)  The Subnet Mask is 255.255.255.0.  Input the IP Address of the Gateway (the router on your network.) Click Apply if you have made any changes. Hexadecimal digits consist of the numbers 0-9 and the letters A-F ASCII (American Standard Code for Information Interchange) is a codefor representing English letters as numbers from 0-127 Fig. 5.4

It is assigned at the factory and cannot be changed.  Usually you will find this address on a sticker on the device or on the packaging. Note: If you select to use the DWL-900AP+ in Wireless Client mode, you will need to input the WirelessMAC Address of the Access Point you wish to associate with.   The Wireless Bridge and Multi-point Bridge mode are proprietary modes that will require DWL-900AP+’s for both locations.   If you select to use the DWL-900AP+ in Wireless Bridge mode, youwill need to input the Ethernet MAC Address of the remote DWL-900AP+ rather than the Wireless MACaddress.
 16 Using the Configuration Menu  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 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 Fragmentation Threshold within the value range of 256 to 2,346.  Setting the Fragmentation Threshold too low may result in poor performance.  DTIM Interval (Beacon Rate):  (Delivery Traffic Indication Message) Enter a value between 1 and 16384 for the Delivery Traffic Indication Message (DTIM.)  A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.    Transmission Rate: Select the transmission rate for the network  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  Antenna Type: Select Left, Right or both (Diversity) antenna  SSID Broadcast: (Service Set Identifier) Enable or Disable (default) the broadcast of the SSID name across the network.

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.
 26 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.        •  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.) Default
