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.

Hardware Solutions
My computer is experiencing difficulty connecting to the wireless
network.
! Ensure that your PC and wireless access point is powered on.
! Ensure that your wireless adapter is installed correctly and is
active.
! Ensure that your wireless adapter and access point radio signal is
enabled. Review your access point’s documentation for further
instructions.
! Ensure that your wireless adapter for your PC and the wireless
access point have the same security settings that will allow your
computer to access the wireless network. Refer to the
Configuration section of the documentation that came with your
access point.
! Verify that the Access Control List (ACL) is not configured to
block your PC. Refer to the Configuration section of the
documentation that came with your access point.
! Ensure that your wireless adapter is within range of your access

I would like to test to see if my Internet connection is alive.
For this, you will use the ping command to test the connection.
Before attempting, determine the IP Address of your adapter.
1 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.
2 In the Command window, type “ipconfig”.
! You should see an IP address for your adapter, for example:
Ethernet Adapter Local Area Connection:
Connection-specific DNS Suffix.: Example.example.example.com.
IP Address. . . . . . . . . . . . : 192.168.10.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.10.1
3 In the Command window, type ping the Router’s IP address and
press the Enter key. The router’s IP address is most likely the
default gateway.
! If you receive a reply (the first word will be Reply…), then
your computer is connected to the router. Proceed to Step 4.
! If you do NOT receive a reply, try from a different computer to
verify that the first PC is not the cause of the problem.
4 In the Command window, type ping and your ISP’s default
gateway and press the Enter key. You can determine your ISP’s
default gateway by examining your modem and or router. Refer to
the instructions provided with your modem/router.
! If you receive a reply (It might look something like this: Reply
from 216.109.125.72…), then your connection to the Internet
is alive and well.
! If you do NOT receive a reply, try from a different computer to
verify that the first PC is not the cause of the problem.
5 If you cannot determine your ISP’s default gateway, ping
Yahoo.com or another known web location.

In a client/server architecture, a client is a computer that requests
files or services such as file transfer, remote login, or printing
from the server. On an IEEE 802.11b/g wireless LAN, a client is
any host that can communicate with the access point. Also called
a CPE. A wireless client is also called a “station.” Also see server.
Coaxial Cable
A type of cable consisting of a center wire surrounded by
insulation and a grounded shield of braided wire. The shield
minimizes electrical and radio frequency interference. Coaxial
cable has high bandwidth and can support transmission over long
distances.
CPE
Customer Premise Equipment: typically computers, printers, etc,
that are connected to the gateway at the subscriber location. CPE
can be provided by the subscriber or the cable service provider.
Also called a client.

D
Default Gateway
A routing device that forwards traffic not destined to a station
within the local subnet.
DHCP

eliminates the need to manually assign static IP addresses by
“leasing” an IP address and subnet mask to each client. It
enables the automatic reuse of unused IP addresses.
DMZ
DeMilitarized Zone. This service opens one IP address to the
Internet, usually for online gaming, and acts as a buffer between
the Internet and your network.
DNS
The Domain Name System is the Internet system for converting
domain names (like www.motorola.com) to IP addresses. A DNS

GLOSSARY SECTION 5
SECTION 5, GLOSSARY 5-3
you access the world-wide web, a DNS server translates the URL
displayed on the browser to the destination website IP address.

DSSS
Direct-Sequence Spread Spectrum. DSSS is a transmission
technology used in WLAN transmissions where a data signal at
the sending station is combined with a higher data rate bit
sequence, or chipping code, that divides the user data according
to a spreading ratio. The chipping code is a redundant bit pattern
for each bit that is transmitted, which increases the signal's
resistance to interference. If one or more bits in the pattern are
damaged during transmission, the original data can be recovered
due to the redundancy of the transmission.
Dynamic IP Address

server. The opposite of Static IP Address.
