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 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. 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 2.4 GHz 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 2.4 GHz 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. 13 D-Link DWA-121 User ManualSection 2 - Installation Connecting to a Wireless Network Using Windows 10 To connect to a wireless network using Windows 10, you will need to know the wireless network name (SSID) and Wi-Fi password

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 office 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 efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial 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. 27 D-Link DWA-121 User ManualAppendix A - Wireless Basics What 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 office 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. 28 D-Link DWA-121 User ManualAppendix A - Wireless Basics 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. Who uses wireless?

Wireless technology as become so popular in recent years that almost everyone is using it, whether its for home, office, 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 Office and Home Office Stay on top of everything at home as you would at office Remotely access your office network from home Share Internet connection and printer with multiple computers No need to dedicate office space 29 D-Link DWA-121 User ManualAppendix A - Wireless Basics Where is wireless used?

Wireless technology is expanding everywhere not just at home or 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 Internet from remote locations like: airports, hotels, coffee shops, libraries, restaurants, and convention centers. Wireless network is 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, Nanowaves, and televisions as far away as possible from the router/access point. This would significantly reduce any interference that the appliances might cause since they operate on same frequency. Security Dont let your 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. 30 D-Link DWA-121 User ManualAppendix 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. 31 D-Link DWA-121 User ManualAppendix A - Wireless 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. 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. 32 D-Link DWA-121 User ManualAppendix 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:

Click on Start > Control Panel (make sure you are in Classic View). Double-click on the Network and Sharing Center icon and then click on Change adapter settings. Right-click on the Local Area Connection which represents your D-Link wireless network adapter which will be connected to your network. Highlight Internet Protocol Version 4 (TCP /IPv4) and click Properties. Click Use the following IP address and enter an IP address that is on the same subnet as your network or LAN IP address on your router or network. Example: If the routers 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 Default Gateway the same as the LAN IP address of your router or gateway. Set Primary DNS the same as the LAN IP address of your router or gateway. The Secondary DNS is optional (you may enter a DNS server from your ISP). Click OK to save your settings. 33 D-Link DWA-121 User ManualAppendix B - Networking Basics Technical Specifications Standards IEEE 802.11n IEEE 802.11g IEEE 802.11b Bus Type USB 2.0 (1.1 compatible) Security Wi-Fi Protected Access (WPA & WPA2) Wi-Fi Protected Setup PBC Frequency Range 2.4 GHz to 2.4835 GHz Operating Voltage 5 V DC +/- 10%
