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 ofwalls, 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 businessThe key to maximizing wireless range is to follow these basic guidelines:
1.
3.
Keep the number ofwalls and ceilings between the D-Link adapter and other network devices to a minimum - each waII orceiling
can reduce your adapter's range from 3-90 feet (1-30 meterst) Position your devices so that the number of walls or ceilings is
minimized,
Be aware of the direct line between network devices, A wall that is 15 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,
Building Materials make a difference A solid metal door or aluminum studs may have a negative effect on rangeTry 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,
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise,
If you are using 2A4GHz 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 possibIeThe base transmits a signal even if the phone in not in use,

. 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 802.1 Ti and
uses Advanced Encryption Standard instead ofTKIP
- 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-specific MAC address, which is relatively simpleto 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/WPAZ-PSK uses a passphrase or key to authenticate your wireless connections The key is an alpha-numeric password between 8 and 63
characters long. The password can include symbols (l?*&_) and spaces, This key must be the exact same key entered on your wireless router or
access point,
WPANi/PAZ 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 Basics
D»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 office environments, and public areas such as airports, coffee shops and universities, Innovative ways
to utilize WLAN technology are helping people to workand 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.WireIess 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,

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 networks
Why D-LinkWireIess?
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 similarto 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,
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,

Tips
Wireless technology is expanding everywhere not just at home or office. 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’i
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 first 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.
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. Ifyou 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 significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
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.

Wireless Modes
There are basically two modes of networking:
- Infrastructure — AII wireless clients will connect to an access point or wireless routers
- 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.
