Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The DWA-142 offers the following types of security:
- WPA2 (Wi-Fi Protected Access 2)
- WPA (Wi-Fi Protected Access)
- WEP (Wired Equivalent Privacy)
- WPA2-PSK (Pre-Shared Key)
- WPA-PSK (Pre-Shared Key)
- 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 defined 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 defined so that you can change keys easily.
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-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-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.

Make sure that the DWA-142 Wireless Adapter is properly seated in the computer’s USB port.
If Windows does not detect the hardware upon insertion of the adapter, make sure to completely remove drivers that were previously loaded. -
The computer with the DWA-142 installed is unable to connect to the wireless network and/or the Internet.
• Check that the LED indicators for the broadband modem are indicating normal activity. If not, there may be a problem with the broadband connection.
• Check that the LED indicators on the wireless router are functioning properly. If not, check that the AC power and Ethernet cables are firmly connected.
• Check that the IP Address, subnet mask, gateway, and DNS settings are correctly entered for the network
• In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the settings for the wireless clients and access points. The SSID factory default setting for D-Link products is default.
(Double-click on the WLAN icon in the taskbar. The Link Info screen will display the SSID setting.)
• In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please note that it might be necessary to set up one client to establish a BSS (Basic Service Set) and wait briefly before setting up other clients. This prevents several clients from trying to establish a BSS at the same time, which can result in multiple singular BSSs being established, rather than a single BSS with multiple clients associated to it.
Check that the Network Connection for the wireless client is configured properly. Select AP (Infrastructure) when connecting to an access point and select Ad-Hoc mode when connecting without an access point. Double-click on the WLAN icon in the taskbar > click on Configuration to change the settings for the wireless adapter.
If Security is enabled, make sure that the correct encryption keys are entered on both the DWA-142 and the access point. Double-click on the WLAN icon in the taskbar > click Encryption. Check to see that the key selected is set to the same key as other devices on the network.
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:
- 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.
- 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.
- 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.
- 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 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.
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 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.
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.
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.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone
is using it, whether it’s 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
Where is wireless used?
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”.
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.
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 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 – 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-142 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 AdHoc mode to communicate.
Networking Basics
Check your IP address
After 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 firewall 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.
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:
Step 1
Windows® XP – Click on Start > Control Panel > Network Connections.
Windows® 2000 – From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your D-Link network
adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same
subnet as your network or the LAN IP address on your router.
Example: If the router´s 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 (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1).
The Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
