10D-Link DWA-121 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 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 dierence. A solid metal door or aluminum studs may have a negative eect 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.

33D-Link DWA-121 User ManualSection 4 - Wireless SecurityWireless SecurityThis section will show you the dierent levels of security you can use to protect your data from intruders. The DWA-121 oers 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)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 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 snied 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.

Innovative ways to utilize WLAN technology are helping people to work and communicate more e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
51D-Link DWA-121 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 o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 aord. 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 dierent 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.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 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.
52D-Link DWA-121 User ManualAppendix A - Wireless BasicsWho uses wireless?   Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, o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 Oce and Home Oce  • Stay on top of everything at home as you would at oce  • Remotely access your oce network from home  • Share Internet connection and printer with multiple computers  • No need to dedicate oce space
53D-Link DWA-121 User ManualAppendix A - Wireless BasicsWhere is wireless used? Wireless technology is expanding everywhere not just at home or o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 wireless desktop adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: Airports, Hotels, Coee 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 PointMake 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.Security Don’t let your next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA security feature on the router. Refer to product manual for detail information on how to set it up.
54D-Link DWA-121 User ManualAppendix A - Wireless BasicsThere 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. Unfortunately 802.11g/n products such as the DWA-121 do not support ad-hoc mode.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.* Not supported with the DWA-121.Wireless Modes
