Wireless (Select Models Only) Hardware and Software Guide 5–3 802.11 Wireless Devices (Select Models Only) A computer with an 802.11 wireless device can access a wireless local area network (commonly referred to as wireless network, wireless LAN, or WLAN), which is composed of other computers and accessories linked by a wireless router or a wireless access point. ■A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points that can handle a large number of computers and accessories and can separate critical network functions. ■A home or small office WLAN typically uses a wireless router, which enables several wireless and wired computers to share an Internet connection, a printer, and files without additional pieces of hardware or software. ✎The terms wireless access point and wireless router are often used interchangeably. ■Computers with 802.11 wireless devices may support 1 or more of 3 industry standards: ❏802.11b, supports data rates of up to 11 Mbps and operates at a frequency of 2.4 GHz. ❏802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g WLAN device is backward compatible with 802.11b devices, so they can operate on the same network. ❏802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz. ✎802.11a is not compatible with 802.11b and 802.11g. For information on identifying the type of wireless device in your computer, refer to “ Identifying an 802.11 Wireless Device.”
5–4 Hardware and Software Guide Wireless (Select Models Only) Setting Up a WLAN in Your Home Microsoft Windows XP supports WLAN configuration with the Wireless Network Connection feature. To set up a WLAN and connect to the Internet in your home, you need the following equipment: ■A broadband modem (either DSL or cable) 1 and high-speed Internet service purchased from an Internet service provider (ISP). ■A wireless router (purchased separately) 2. ■Your wireless computer 3. The illustration below shows an example of a wireless network installation that is connected to the Internet. As your network grows, additional wireless and wired computers can be connected to the network to access the Internet. ✎If you need technical assistance to install your home WLAN, contact the router manufacturer or your ISP.
Wireless (Select Models Only) Hardware and Software Guide 5–5 Connecting to a WLAN in Your Home To connect to a WLAN connection in your home: 1. Be sure that your 802.11 wireless device is on. If it is on, the wireless lights are on. If the wireless lights are off, turn on the wireless device. 2. Be sure that your router is correctly installed and configured. For instructions, refer to your router user guides. 3. Use the Wireless Network Connection feature of Microsoft Windows XP to connect your computer to the WLAN. ✎Functional range for subsequent WLAN connections will vary, depending on your computer WLAN implementation, router manufacturer, and interference from walls and other electronic devices. For more information about connecting to a WLAN in your home: ■Refer to information from your ISP and the user guides included with your wireless router and other WLAN equipment. ■Access the information and Web site links provided in the Help and Support Center.
5–6 Hardware and Software Guide Wireless (Select Models Only) Connecting to a Public WLAN Contact your ISP or search the Web for a list of public WLANs near you. When you are within range of a public WLAN, a Wireless Network Connection interactive message is displayed at the bottom of your computer screen. Check with each public WLAN location for cost and connection requirements. Using Wireless Security Features When you set up your home WLAN or access an existing public WLAN, always be sure that security features are protecting the WLAN. If you do not enable security on your WLAN, an unauthorized wireless user can access your information and use your Internet connection without your knowledge. The most common security levels are Wi-Fi Protected Access (WPA)-Personal and Wired Equivalent Privacy (WEP). In addition to enabling WPA-Personal or WEP security encryption on the router, you may want to use one or more of the following security measures: ■Change the default network name (SSID) and password. ■Use a firewall. ■Set security on your Web browser. ■Enable MAC address filtering on the router.

5–8 Hardware and Software Guide Wireless (Select Models Only) Bluetooth Wireless Devices (Select Models Only) A Bluetooth wireless device provides short-range wireless communications that replace the physical cable connections that traditionally link electronic devices such as ■Network access points. ■Computers (desktop, notebook, PDA). ■Phones (cellular, cordless, smart phone). ■Imaging devices (printer, camera). ■Audio devices (headset, speakers). The devices are represented in the Bluetooth for Windows software by graphical icons. The Bluetooth for Windows software provides the following functions: ■Personal Information Management (PIM) item transfer—Enables the exchange of information files such as business cards, calendar items, notes, and message items between Bluetooth computers or devices. ■PIM synchronization—Synchronizes PIM data between a Bluetooth wireless device and a computer, PDA, or cell phone using Bluetooth. ■File Transfer—Enables the exchange of files between Bluetooth computers or devices. ■Network access (Personal Area Networking Profile)—Enables 2 or more Bluetooth devices to form an ad hoc (peer-to-peer) network. Also provides a mechanism that enables a Bluetooth device to access a remote network through a network access point. The network access points can be traditional LAN data access points or group ad hoc networks that represent a set of devices that are attached only to one another.
