4 Introduction The D-Link AirPlus G DWL-G122 Wireless USB Adapter is a convenient Plug & Play USB 2.0 solution that brings wireless networking to your laptop or desktop PC. With transfer rates up to 54Mbps you can connect to a wireless network at home, at the office or at any wireless hotspot. Now you can stay connected wherever you are and wherever you go. The DWL-G122 is Wi-Fi compliant, meaning that it can connect and interoperate with other 802.11b or 802.11g Wi-Fi-compliant wireless routers, access points and adapters. The DWL-G122 connects to any available USB port on a laptop or desktop Windows and Macintosh-based computer and also includes a USB cradle. With the optional USB cradle, the DWL-G122 can be positioned virtually anywhere at a workstation to achieve the best available wireless signal reception - whether that workstation is in your office, on your deck or patio, by the pool, at the local coffee shop, or in an airport terminal while waiting to board your next flight. The adapter works with Apple Mac OS X (v10.2x or later) Jaguar, Microsoft Windows XP, Windows 2000 and other Windows operating systems to ensure that you’ll be up and running on a wireless network in just a matter of seconds. Using its default settings, the DWL-G122 automatically connects to other D-Link Air or AirPlus wireless products as soon as it’s active. In addition to featuring 64- or 128-bit WEP encryption, the DWL-G122 offers the added security of WPA(Wi-Fi Protected Access)/WPA2 when used with other WPA / WPA2 devices in a network with a RADIUS server. For home users that will not incorporate a RADIUS server in their network, the security for the DWL-G122, used in conjunction with other WPA-compatible 802.11 products, will still be much stronger than ever before when you use the Pre- Shared Key mode of WPA / WPA2. TM 5 Features and Benefits Provides high-speed wireless connection at up to 54Mbps ** 2 Environmental factors may adversely affect range 1 WPA2 is only for Windows users
Better Security with WPA/WPA2 1 - In addition to 64-,128-bit WEP encryption,you can also securely connect to a wireless network using WPA(Wi-Fi Protected Access) providing you a much higher level of security for your data and communication than has previously been available. Convenience of Plug & Play installation Compact size for placement anywhere Fully 802.11b/802.11g compatible USB 2.0 standard


Powered by the USB port; no external power source is required


User-friendly configuration and diagnostic utilities Supports Infrastructure networks via an access point and Peer-to-Peer communication in Ad-Hoc mode Connects at up to 328 feet indoors 2


One year warranty
Optimal wireless reception using its cradle (included). Position the DWL-G122 almost anywhere in your workspace to achieve the best reception possible.
6 Wireless Basics 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. 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. 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 to many users. 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 Implementatio…
