24D-Link DWA-140 User ManualSection 4 - Wireless SecurityWireless SecurityThis section will show you the different levels of security you can use to protect your data from intruders. The DWA-140 offers the following types of security:• WPA2 (Wi-Fi Protected Access 2)     • WPA2-PSK (Pre-Shared Key)• WPA (Wi-Fi Protected Access)      • WPA-PSK (Pre-Shared Key)• WEP (Wired Equivalent Privacy)      • 802.1x (RADIUS)What is WEP?WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted from one wireless device to another.To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are dened by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be dened so that you can change keys easily.
25D-Link DWA-140 User ManualSection 4 - Wireless SecurityWhat 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 haven’t 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 computer’s  hardware-specic 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-PSK/WPA2-PSK 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 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.

38D-Link DWA-140 User ManualSection 2 - InstallationWireless Installation ConsiderationsThe 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 adapter’s 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 (sh tanks), mirrors, le 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.
39D-Link DWA-140 User ManualAppendix A - Wireless BasicsD-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. Strictly adhering to the IEEE standard, the D-Link wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers.A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and ofce 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 efciently. Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for 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. Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN.  A Wireless Router is a device used to provide this link.Wireless Basics
40D-Link DWA-140 User ManualAppendix A - Wireless BasicsWhat is Wireless?Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or ofce network.Why D-Link Wireless?   D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your network.How does wireless work?   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 as seen in the picture, 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.
41D-Link DWA-140 User ManualAppendix A - Wireless BasicsWireless 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 doesn’t 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.Who uses wireless?   Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, ofce, business, D-Link has a wireless solution for it.Home  • Gives everyone at home broadband access  • Surf the web, check email, instant message, and etc  • Gets rid of the cables around the house  • Simple and easy to use Small Ofce and Home Ofce  • Stay on top of everything at home as you would at ofce  • Remotely access your ofce network from home  • Share Internet connection and printer with multiple computers  • No need to dedicate ofce space
42D-Link DWA-140 User ManualAppendix A - Wireless BasicsWhere is wireless used?   Wireless technology is expanding everywhere not just at home or ofce. People like the freedom of mobility and it’s 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 Internet from remote locations like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.Wireless network is easy to setup, but if you’re installing it for the rst time it could be quite a task not knowing where to start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.TipsHere 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 would signicantly reduce any interference that the appliances might cause since they operate on same frequency.
43D-Link DWA-140 User ManualAppendix A - Wireless BasicsSecurity   Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.     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, such as two or more DWA-130 wireless network USB Adapters.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.Wireless Modes
44D-Link DWA-140 User ManualAppendix B - Networking BasicsNetworking BasicsCheck your IP addressAfter you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.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.If  the  address  is  0.0.0.0,  check  your  adapter installation,  security  settings,  and  the  settings on your router. Some rewall software programs may  block  a  DHCP  request  on  newly  installed adapters. If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network settings.
