Wireless Basics D-Link 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. 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 computer network that transmits and receives data with radio signals instead of wires.
Wireless Basics (continued) Installation Considerations The DWL-G122 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.
Getting Started With its default settings, the DWL-G122 will connect with other D-Link AirPlusTM G products, right out of the box. There are basically two modes of networking: Infrastructure – using an access point or router, such as the DI-624. 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-G122 Wireless Network USB adapters.
Getting Started (continued) Setting up a Wireless Infrastructure Network 1 2 3 DWL-G122 DWL-G122 4 5 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.
