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.

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 Cardbus 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.

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 DIR-825 wireless network Cardbus 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 cardbus adapters. All the adapters must be in Ad-Hoc

mode to communicate.

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±

(Windows® 7/Vista® users type

cmd

in the

Start.Search

box.)

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.
