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 ofce 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 -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 ofce, on your deck or patio, by the pool, at the local coffee shop, or in an airport terminal while waiting to board your next ight. The adapter works with Microsoft Windows XP and Windows 2000 operating systems to ensure that youll 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 its active. In addition to featuring 64- or 128-bit WEP encryption, the DWL-G122 offers the added security of WPA (Wi-Fi Protected Access) when used with other WPA 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.

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. WLANs are used increasingly in both home and ofce 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 efciently. Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial to 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 signicantly improve worker efciency. Low Implementation Costs - WLANs are easy to set up, manage, change and relocate. Networks that frequently change can benet 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 ofce. Inexpensive Solution - Wireless network devices are as competitively priced as conventional Ethernet network devices. Scalability - WLANs can be congured in a variety of ways to meet the needs of specic applications and installations. Congurations 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.

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. The key to maximizing wireless range is to follow these basic guidelines:
1 Keep the number of walls and ceilings between the DWL-G122 and other
network devices to a minimum - each wall or ceiling can reduce your DWL-G122s 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. devices or appliances that generate RF noise.
4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

Getting Started

With its default settings, the DWL-G122 will connect with other TM D-Link AirPlus 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. 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):
