D-Link DWA-171 User Manual 6 Section 2 - Installation Installation This section will walk you through the installation process. If you have a built-in wireless adapter, please disable it in device manager before installing your D-Link adapter. Also, if you have previously installed another wireless adapter, please make sure any software is uninstalled. Getting Started Before installing your new D-Link wireless adapter, please verify the following:

Remove any previous installations of wireless adapters Disable any built-in wireless adapters Verify the settings such as the SSID and security settings of the network(s) you want to connect to Remove Existing Installations If youve installed a different manufactures adapter or a different model D-Link adapter, make sure the software is uninstalled before installing the new software. Some utilities may cause a conflict with the new software. If you plan to use multiple adapters at different times, make sure the utilities are not set to load when your computer boots up. Windows 7, Vista and XP users may use the built-in wireless utility for all adapters. To remove any old software:

Windows 7 users: Click Start > Control Panel > Uninstall Programs. Windows Vista/XP users: Click Start > Control Panel > Add or Remove Programs. D-Link DWA-171 User Manual 7 Section 2 - Installation Disable Other Wireless Adapters Most newer laptops may include a built-in wireless adapter. To prevent any conflicts with the D-Link wireless adapter, it is recommended to disable the wireless adapter (as well as any unused Ethernet adapters). From the desktop, right-click on the My Computer icon and select Properties. Click the Hardware tab and then click Device Manager. Scroll down the list and click the

D-Link DWA-171 User Manual 9 Section 2 - Installation Wireless Installation Considerations The D-Link wireless adapter lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. 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 D-Link adapter and other network devices to a minimum - each wall or ceiling can reduce your adapters 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 make a difference. A solid metal door or aluminum studs may have a negative effect on range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal. 4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise. 5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.

The DWA-171 offers the following types of security:

WPA/WPA2-Personal WPA/WPA2-Enterprise What is WPA?

WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy). The 2 major improvements over WEP:

Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys havent been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP. User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP regulates access to a wireless network based on a computers hardware-specific MAC address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network. WPA/WPA2-Personal uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or access point. WPA/WPA2-Enterprise incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public key encryption system to ensure that only authorized network users can access the network.

Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There are two different types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN). Wireless Local Area Network (WLAN) In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues. Wireless Personal Area Network (WPAN) Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away. Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesnt use nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.

Wireless technology is expanding everywhere not just at home or the office. People like the freedom of mobility and its becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called hotspots. Using a D-Link USB Adapter with your laptop, you can access the hotspot to connect to the Internet from remote locations like:

Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers. Wireless networks are easy to setup, but if youre installing it for the first time it could be quite a task not knowing where to start. Thats why weve put together a few setup steps and tips to help you through the process of setting up a wireless network. Tips Here are a few things to keep in mind, when you install a wireless network. Centralize your router or Access Point Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have a two-

story home, you may need a repeater to boost the signal to extend the range. Eliminate Interference Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This can significantly reduce any interference that the appliances might cause since they operate on the same frequency. Security Dont let your next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on WPA/WPA2 security features on the router. Refer to the product manual for detailed information on how to set it up. D-Link DWA-171 User Manual 52 Appendix A - Wireless Basics Wireless Modes There are basically two modes of networking:

Infrastructure All wireless clients will connect to an access point or wireless router. Ad-Hoc Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer. An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point. An Ad-Hoc network contains only clients, such as laptops with wireless USB Adapters. All the adapters must be in Ad-Hoc mode to communicate. D-Link DWA-171 User Manual 53 Appendix B - Networking Basics Networking Basics Check your IP address After you install your new D-Link wireless adapter and have established a wireless connection, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. router) automatically. To verify your IP address, please follow the steps below. Windows XP Users Click on Start > Run. In the run box type cmd and click OK. At the prompt, type ipconfig and press Enter. This will display the IP address, subnet mask, and the default gateway of your adapter. Windows 7/Vista Users Click Start > All Programs > Accessories > Command Prompt. You may need administrative access to run this application. For all additional prompt windows inquiring of running the command prompt application, select Yes, OK, or Continue. At the prompt, type ipconfig and press Enter. This will display the IP address, subnet mask, and default gateway of your adapter. If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some firewall software programs may block a DHCP request on newly installed adapters. D-Link DWA-171 User Manual 54 Appendix B - Networking Basics Statically Assign an IP Address If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
