Wireless Basics (continued) The DWL-120 is compatible with the D-Link Air 802.11b family of products which include: 2.4GHz Wireless Cardbus Adapters used with laptop computers (DWL-650) 2.4GHz Wireless PCI cards used with desktop computers (DWL-520) Wireless Access Points (DWL-900AP) Standards-Based Technology Based on the IEEE 802.11b standard, the DWL-120 is interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps.
Wireless Basics (continued) Installation Considerations The D-Link Air DWL-120 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.
Getting Started With its default settings, the DWL-120 will connect with other D-Link Air products, right out of the box. There are basically two modes of networking: Infrastructure – using an Access Point, such as the DWL-900AP+. Ad-Hoc – directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more DWL-120 wireless network USB adapters.
Getting Started 1 Setting up a Wireless 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 and assign your IP Address; share printers and files. 2 3 4 Using the Configuration Menu - learn the settings for the DWL-120, using the web-based interface. Troubleshooting - learn how to check for common installation issues and other tips for troubleshooting.
Getting Started Setting up a Wireless Ad Hoc Network Install the D-Link Air DWL-120 Wireless USB adapter into the desktop computer. See the Quick Installation Guide included with the product for installation instructions. Install a wireless network adapter into the laptop computer. In the example above the DWL-650+ or DWL-650 may be installed into a laptop computer. See the Quick Installation Guide included with the product.
Using the Configuration Utility With its default settings, the DWL-120 will connect with other D-Link Air products, right out of the box. D-Link Air DWL-120 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. When the computer is started, the Configuration Utility starts automatically and the system tray icon is loaded in the toolbar (see illustration below.
Using the Configuration Utility Configuration Network Type: Infrastructure is the factory default setting. Ad-Hoc mode is used for peer to peer networking. See the Getting Started section in this manual for examples of these network types. SSID: The Service Set Identifier is the name assigned to the wireless network. The factory SSID setting is set to default. Make changes here to match the SSID on existing Wireless Router or Access Point.
Using the Configuration Utility Configuration>WEP Setting If you enable WEP encryption make sure to match the WEP encryption on the router or access point. WEP stands for Wired Equivalent Privacy. It is a security protocol for Wireless Local Area Networks Hexadecimal format consists of numbers 0-9 WEP type: Select 128 bit WEP or 64 bit WEP encryption and letters a-f.
Using the Configuration Utility Profiles New: Click New to create a new profile; a pop-up window will appear allowing you to configure the new profile. (See the example on the next page.) Remove: Highlight the profile you wish to remove; click Remove Edit: Highlight the profile you wish to edit; click Edit; a pop-up window will appear allowing you to edit the profile. (See the example on the next page.
Using the Configuration Utility Network Type: Select Infrastructure or Ad-Hoc Edit/Create new profile SSID: All devices on the network must share the same SSID to be able to communicate TxRate: Choose the data rate speed WEP: Choose Enable or Disable. Disable is the default setting. If you enable WEP, you must Enable WEP on all devices on the network, in order to communicate.
Using the Configuration Utility About The About tab displays the utility (firmware) version.
