Overview
Simple Home Network Diagram
Your wireless notebook adapter card, allows you to access files, printers, and an Internet
connection on your network. A sample Local Area Network (LAN) is shown below:
In the example above, the Internet communicates with the modem, which in turn
communicates with the router. The router acts as the gateway to your network, sending
information to whichever device asks for information. The adapter card enables your
notebook PC to be part of the wireless network.
Wireless Connections
Your wireless adapter card uses a radio transmission technology defined by the Institute of
Electrical and Electronics Engineers (IEEE) called 802.11 Wireless Fidelity (Wi-Fi). This
standard is subdivided into distinct categories of speed and the frequency spectrum used,
designated by the lower case letter after the standard.
For example, your adapter card can work with both the ‘b’ and ‘g’ specifications. The
802.11b specification transmits data rates up to 11 Mbps while the 802.11g specification
transmits data rates up to 54 Mbps. Both standards operate in the 2.4 GHz range. These
are theoretical speeds so your performance may vary.
A Word About Data Rates: Data rate is the speed at which individual bits of data flow through a channel. It is
not the same speed at which entire files are uploaded or downloaded. These speeds will vary, and are often
less than the maximum data rate. Upload and download speeds are affected by several factors including, but
not limited to: the capacity of and the services offered by your cable operator or broadband service provider,
channel capacity, network traffic, computer equipment, type of server, number of connections to server, and
availability of Internet router(s).

Section 2:Installation
Before You Begin
You need to collect information so that you can setup your WN825 correctly. Depending
upon where you are connecting, the type of information required is divided between
business (enterprise users) and home settings (small office/home office).
Also, you need to consider the type of security to enable for your wireless connection. A
discussion of the types of security available follows this section.
Enterprise Users
Obtain the following information from your network administrator:
Network names (SSID) of the specific wireless networks to which you are going to
connect.
WPA (Wi-Fi Protected Access) wireless network key information (may include network
authentication type, encryption type, network key) for any WPA enabled networks to
which you want to connect.
WEP (Wired Equivalent Privacy) wireless network key information (network key) for any
WEP enabled networks to which you want to connect.
For Microsoft® Windows® networking, the customer name and workgroup name.
For a network account, the domain name, a user name and password.
An IP address (if not using a DHCP server).
Networks connected to an authentication server, if any.
WN825
2-1
Section 2
Installation
Small Office/Home Office Users
The access point that communicates with the WN825 has a pre-assigned network name
(SSID) that the WN825 recognizes upon startup.
If you are setting up a new wireless network with WEP security, the WN825 should use
the same network key you used for your network.
For more information on WEP security, see “Security Options”.
If you are connecting to an existing WEP enabled network, obtain the network key from
the access point.
If you are connecting to a WPA-enabled access point, obtain the WPA (Wi-Fi Protected
Access) wireless network key information (network authentication type, encryption type,
network key) from the access point.
Security Options
The WN825 is designed for both the home user and business. WPA (Wi-Fi Protected
Access) protocol is designed into the WN825. WPA is a powerful, standards-based,
interoperable security technology for wireless local area networks (the subset of the future
IEEE Std 802.11i standard) that encrypts data sent over radio waves.
The WPA protocol was developed to overcome the weaknesses of the WEP (Wired
Equivalent Privacy) protocol. Both protocols require the use of network key information, and
either protocol can be enabled or disabled, depending on the type of network connection
being made.
Various options are available for selecting network authentication and data encryption. It is
important for you to understand these options when deciding which (if any) security protocol
to use.
Security Example
If you want to use a more secure protocol, the wireless network to which you are
connecting must also support that protocol. For example, you decide to enable WPA-PSK
on your WN825, a good choice because of the robust security WPA-PSK offers. However,
the slightly older wireless network you want to connect to only supports WEP, which means
that you cannot use WPA (and should use WEP) because the security protocols must
match between the network adapter and the access point.

This feature applies only to the WN825GP Wireless Notebook Adapter.
When enabled, the wireless data throughput of a WN825GP Wireless Notebook Adapter is

Troubleshooting
I would like to test if my Internet connection is live.
Use the ping command to test the connection. Before attempting, determine the IP Address
of your adapter.
Open a command prompt by clicking Start and Run.
For Windows 98 and ME, in the Open field, type command and press Enter or OK.
For Windows 2000 and XP, type cmd. Or, navigate using your Start button to
Programs>Accessories>Command Prompt.
In the Command window, type ipconfig.
