5 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. 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 Wireless Local Area Network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. WLANs 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. People use WLAN 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 are easy to set up, manage, change and relocate. Networks that frequently change can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical. Installation and Network Expansion - Installing a WLAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires cannot go - even outside the home or office. Scalability â€“ 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 networks to accommodate hundreds or thousands of users, depending on the number of wireless devices deployed. Inexpensive Solution - Wireless network devices are as competitively priced as conventional Ethernet network devices.
6 Wireless Basics (continued) The DWL-650 is compatible with 802.11b wireless products, which include:
! D-Link AirPlus DWL-650+
2.4GHz Wireless Cardbus Adapter used with laptop computers
! D-Link Air DWL-520, D-Link AirPlusDWL-520+
2.4GHz Wireless PCI cards used with desktop computers
! D-Link AirPlus DWL-900AP+
Enhanced 2.4GHz Wireless Access Point
! D-Link AirPlus DI-614+, DI-714P+
Enhanced 2.4GHz Wireless Broadband Routers Standards-Based Technology Based on the IEEE 802.11b standard, the DWL-650 is also interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps. Installation Considerations The D-Link Air DWL-650 lets you access your network, using a wireless connection, from virtually anywhere within its operating range. 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 DWL-650 and
other network devices to a minimum - each wall or ceiling can reduce your D-Link Air 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! 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 generate RF noise.
7 Getting Started With its default settings, the DWL-650, when activated, will connect with other D-Link Air products, right out of the box.
There are basically two modes of networking:
! Infrastructure â€“ using an Access Point or Router, such as the DI-614+
! Ad-Hoc â€“ directly connecting to another computer, for peer-to- peer communication, using wireless network adapters on each computer, such as two or more DWL-650 wireless network 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 Router. The Infrastructure Network example shown on the following page contains the following D-Link network devices (your existing network may be comprised of other devices):
A wireless Router - D-Link AirPlus DI-614+
A laptop computer with a wireless adapter - D-Link Air DWL-650
A desktop computer with a wireless adapter - D-Link Air DWL-520
A Cable modem - D-Link DCM-200
Getting Started (continued) Setting up a Wireless Infrastructure Network 2 1 3 4 6 5 Please remember that D-Link Airwireless devices are pre-configured to connect together, right out of the box, with their default settings. For a typical wireless setup at home (as shown above), please do the following:
You will need broadband Internet access (a Cable or DSL-subscriber line into your home or office)
Consult with your Cable or DSL provider for proper installation of the modem
Connect the Cable or DSL modem to your broadband router (see the Quick Installation Guide included with your router.)
Install the D-Link Air DWL-520 wireless PCI adapter into an available PCI slot
on your desktop computer. (See the Quick Installation Guide included with the DWL-520.)
Install the D-Link Air DWL-650 wireless Cardbus adapter into a laptop computer.
(See the Quick Installation Guide included with the DWL-650.)
If you wish, you may connect a computer that is equipped with an Ethernet
network adapter (such as a DFE-530TX+) to the router also.
Getting Started (continued) Setting up a Wireless Ad Hoc Network
Install the Wireless PCI adapter(e.g., DWL-520) into the desktop computer. (See the Quick Installation Guide included with the product for installation instructions.)
Install the DWL-650 wireless Cardbus adapter into a laptop computer. (See the Quick Installation Guide included with the product.)
Set the wireless configuration for the adapters to Ad-Hoc mode, set the adapters to the same channel, and assign an IP Address to each computer on the Ad-Hoc network. (See Box below) IP Address
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 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.
Using the Configuration Utility D-Link Air DWL-650 uses the Configuration Utility as the management software. The utility provides the user an easy interface to change any settings related to the wireless adapter. After you have completed the installation of the DWL-650 (refer to the Quick Installation Guide that came with your purchase) whenever you start the computer, the Configuration Utility starts automatically and the system tray icon is loaded in the toolbar (see illustration below*.) Clicking on the utility icon will start the Configuration Utility. Another way to start the Configuration Utility is to click on Start>Programs>D- Link Air>D-Link Air Utility.
If you are using Windows XP, you can use either the Zero Configuration Utility or the D-Link Configuration Utility.
To use the D-Link Configuration Utility with XP, right-click on the Wireless network icon in the taskbar in the lower right-hand corner of your computer screen.
In the window that appears, select View Available Wireless Networks and click the Advanced button.The screen at right will appear.
Select the Wireless Networks tab.
