76 D-Link DWR-921 User Manua\f Appendix A - Wire\fess Basics D-Link wire\fess products are based on industry standards to provide easy-to-use and compatib\fe hi\bh-speed wire\fess connectivity within your home, business or pub\fic access wire\fess networks. Strict\fy adherin\b to the IEEE standard, the D-Link wire\fess fami\fy of products wi\f\f a\f\fow you to secure\fy access the data you want, when and where you want it. You wi\f\f be ab\fe to enjoy the freedom that wire\fess networkin\b de\fivers. A wire\fess \foca\f area network (WLAN) is a ce\f\fu\far computer network that transmits and receives data with radio si\bna\fs instead of wires. Wire\fess LANs are used increasin\b\fy in both home and office environments, and pub\fic areas such as airports, coffee shops and universities. Innovative ways to uti\fize WLAN techno\fo\by are he\fpin\b peop\fe to work and communicate more efficient\fy. Increased mobi\fity and the absence of cab\fin\b and other fixed infrastructure have proven to be beneficia\f for many users. Wire\fess users can use the same app\fications they use on a wired network. Wire\fess adapter cards used on \faptop and desktop systems support the same protoco\fs as Ethernet adapter cards. Under many circumstances, it may be desirab\fe for mobi\fe network devices to \fink to a conventiona\f Ethernet LAN in order to use servers, printers or an Internet connection supp\fied throu\bh the wired LAN. A Wire\fess Router is a device used to provide this \fink. W\freless Bas\fcs
77 D-Link DWR-921 User Manua\f Appendix A - Wire\fess Basics What \fs W\freless? Wire\fess or Wi-Fi techno\fo\by is another way of connectin\b your computer to the network without usin\b wires. Wi-Fi uses radio frequency to connect wire\fess\fy, so you have the freedom to connect computers anywhere in your home or office network. Why D-L\fnk W\freless?

D-Link de\fivers the performance you need at a price you can afford. D-Link has a\f\f the products you need to bui\fd your network. How does w\freless work? Wire\fess works simi\far to how cord\fess phone work, throu\bh radio si\bna\fs to transmit data from one point A to point B. But wire\fess techno\fo\by has restrictions as to how you can access the network. You must be within the wire\fess network ran\be area to be ab\fe to connect your computer. There are two different types of wire\fess networks Wire\fess Loca\f Area Network (WLAN), and Wire\fess Persona\f Area Network (WPAN). W\freless Local Area Network (WLAN) In a wire\fess \foca\f area network, a device ca\f\fed an Access Point (AP) connects computers to the network. The access point has a sma\f\f antenna attached to it, which a\f\fows it to transmit data back and forth over radio si\bna\fs. With an indoor access point as seen in the picture, the si\bna\f can trave\f up to 300 feet. With an outdoor access point the si\bna\f can reach out up to 30 mi\fes to serve p\faces \fike manufacturin\b p\fants, industria\f \focations, co\f\fe\be and hi\bh schoo\f\u campuses, airports, \bo\ff courses, and many other outdoor venues. W\freless Personal Area Network (WPAN) B\fuetooth is the industry standard wire\fess techno\fo\by used for WPAN. B\fuetooth devices in WPAN operate in a ran\be up to 30 feet away. Compared to WLAN the speed and wire\fess operation ran\be are both \fess than WLAN, but in return it doesn’t use near\fy as much power which makes it idea\f for persona\f devices, such as mobi\fe pho\unes, PDAs, headphones, \faptops, speakers, and other devices that operate on batteries.
78 D-Link DWR-921 User Manua\f Appendix A - Wire\fess Basics Who uses w\freless? Wire\fess techno\fo\by as become so popu\far in recent years that a\fmost everyone is usin\b it. Whether it’s for home, office, or business, D-Link has a wire\fess so\fution for it. Home • Gives everyone at home broadband access • Surf the web, check e-mai\f, instant messa\be, etc • Gets rid of the cab\fes around the house • Simp\fe and easy t\uo use Small Office and Home Office • Stay on top of everythin\b at home as you wou\fd at office • Remote\fy access your office network from home • Share Internet connection and printer with mu\ftip\fe computers • No need to dedicate office space
79 D-Link DWR-921 User Manua\f Appendix A - Wire\fess Basics Where \fs w\freless used? Wire\fess techno\fo\by is expandin\b everywhere not just at home or office. Peop\fe \fike the freedom of mobi\fity and it’s becomin\b so popu\far that more and more pub\fic faci\fities now provide wire\fess access to attract peop\fe. The wire\fess connection in pub\fic p\faces is usua\f\fy ca\f\fed “hotspots”. Usin\b a D-Link Cardbus Adapter with your \faptop, you can access the hotspot to connect to Internet from remote \focations \fike Airports, Hote\fs, Coffee Shops, Libraries, Restaurants, and Convention Centers. Wire\fess network is easy to setup, but if you’re insta\f\fin\b it for the first time it cou\fd be quite a task not knowin\b where to start. That’s why we’ve put to\bether a few setup steps and tips to he\fp you throu\bh the process of settin\b up a \uwire\fess network. T\fps Here are a few thin\bs to keep in mind, when you insta\f\f a wire\fess network. Central\fze your Router or Access Po\fnt Make sure you p\face the router/access point in a centra\fized \focation within your network for the best performance. Try to p\face the router/access point as hi\bh as possib\fe in the room, so the si\bna\f \bets dispersed throu\bhout your home. If you have a two-story home, you may need a repeater to boost the si\bna\f to extend the ran\be. El\fm\fnate Interference P\face home app\fiances such as cord\fess te\fephones, microwaves, and te\fevisions as far away as possib\fe from the router/access point. This wou\fd si\bnificant\fy reduce any interference that the app\fiances mi\bht cause since they operate on same frequency. Secur\fty Don’t \fet you next-door nei\bhbors or intruders connect to your wire\fess network. Secure your wire\fess network by turnin\b on the WPA or WEP security feature on the router. Refer to product manua\f for detai\f information on how to set it up.
80 D-Link DWR-921 User Manua\f Appendix A - Wire\fess Basics There are basica\f\fy two modes of networkin\b: • • Infrastructure – A\f\f wire\fess c\fients wi\f\f connect to an access point or wire\fess router. • • Ad-Hoc – Direct\fy connectin\b to another computer, for peer-to-peer communication, usin\b wire\fess network adapters on each computer. An Infrastructure network contains an Access Point or wire\fess router. A\f\f the wire\fess devices, or c\fients, wi\f\f connect to the wire\fess router or access point. An Ad-Hoc network contains on\fy c\fients, such as \faptops with wire\fess cardbus adapters. A\f\f the adapters must be in Ad-Hoc mode to communicate. W\freless Modes
81 D-Link DWR-921 User Manua\f Appendix B - Networkin\b Basics Network\fng Bas\fcs Check your IP address After you insta\f\f your new D-Link adapter, by defau\ft, the TCP/IP settin\bs shou\fd be set to obtain an IP address from a DHCP server (i.e. wire\fess router) automatica\f\fy. To verify your IP address, p\fease fo\f\fow the steps be\fow. C\fick on Start > Run. In the run box type cmd and c\fick OK. (Windows ® Vista™ users type cmd in the Start Search box.) At the prompt, type ipconfig and press Enter. This wi\f\f disp\fay the IP address, subnet mask, and the defau\ft \bateway of your adapter. If the address is 0.0.0.0, check your adapter insta\f\fation, security settin\bs, and the settin\bs on your router. Some firewa\f\f software pro\brams may b\fock a DHCP request on new\fy insta\u\f\fed adapters.
82 D-Link DWR-921 User Manua\f Appendix B - Networkin\b Basics Stat\fcally Ass\fgn an IP address If you are not usin\b a DHCP c\uapab\fe \bateway/router, or you need to assi\bn a static IP address, p\fease fo\f\fow the steps be\fow: Step 1 Windows ® Vista™ - C\fick on Start > Control Panel > Network and Internet > Network and Shar\fng Center > Manage Network Connect\fons. Windows ® XP - C\fick on Start > Control Panel > Network Connect\fons. Windows ® 2000 - From the desktop, ri\bht-c\fick My Network Places > Propert\fes. Step 2 Ri\bht-c\fick on the Local Area Connect\fon which represents your network adapter and se\fect Propert\fes. Step 3 Hi\bh\fi\bht Internet Protocol (TCP/IP) and c\fick Propert\fes. Step 4 C\fick Use the follow\fng IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router. Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set Defau\ft Gateway the same as the LA\uN IP address of your router (192.168.0.1). \u Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP. Step 5 C\fick OK twice to save your settin\bs.
