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-855 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.

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.
(Windows Vista

users type
cmd
in the

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.
