an introduction to wireless networking
1
what is a wireless network?
Any network is a collection of computers and other devices that communicate
with each other.
Wireless networks are built around an access point, that typically includes a
switch or router. This access point routes the signals so that the computers in the
network can share files, folders, printers, and access to the Internet.
Computers communicate with their access point in one of two ways:
❂
in wired networks, Ethernet cables carry the signals to and from the
computer and the access point.
❂
in wireless networks, radio waves transmit the signals to and from special
wireless components in both the computers and the access point.
With some notebooks and computers, you have to purchase a special wireless
component, but with your eMachines 5000 Series notebook, you can go wireless
right out of the box!
why go wireless?
Because it frees you from your desk!
With a wireless home network, you can use your notebook wherever you like.
From the comfort of your sofa, in your kitchen, or on your patio, you can browse
the Internet, send and receive emails, transfer files, and use your printer.
You can even stay connected when you are away from your home, by
connecting to public “hot spots.” These hot spots are becoming more and more
common and are readily available in airports, libraries, book stores, and
coffee shops.

wireless features on your notebook
54gTM, the most advanced wireless networking technology available, is
incorporated into your notebook. Also known as 802.11g, this up-and-coming
wireless networking standard is up to 5 times faster than the widely used, older
standard, 802.11b. Instead of communicating at a maximum speed of
11 megabits per second (Mbps), your notebook, equipped with 802.11g, can
communicate at speeds up to 54 Mbps!
Because 802.11g is backward compatible with Wi-Fi 802.11b networks, you will
be able to access networks that have not yet upgraded to the new standard.
When going wireless with your notebook, you can work faster and play harder:
❂
speed - communicate at speeds up to 5 times faster than 802.11b,
on an 802.11g network.
❂
compatibility - connect to already-installed 802.11b networks.
❂
range - extend the reach of your network, up to 300 feet.
❂
security - protect your notebook and your data with wired equivalent
privacy (WEP) encryption.
❂
resource sharing - share your network resources, such as your broadband
Internet connection, printers, and storage.

an introduction to wireless networking
example of a wireless home network
that includes a desktop computer
A typical home network includes the following:
❂
one desktop computer
❂
your new eMachines notebook
❂
one access point
❂
one broadband Internet connection
❂
one printer, attached to the desktop computer
In this example that includes a current home computer setup, you simply insert
an access point into your current setup to create your network.
Your notebook can join the network as needed, and will share the broadband
connection, the printer, and any files marked for sharing.

setting up your home network
2
When you are ready to set up your home network, you must first consider which
computers or other devices you want to include. Because most home networks
look like the example shown on the previous page (with a notebook computer,
a desktop computer, a broadband Internet connection, and a printer), the
instructions in the rest of this booklet will be based on this common setup.
what do I need to get started?
To set up your wireless home network, you need to obtain the following items:
❂
one access point
❂
one Ethernet cable
access point recommendations
If you need to purchase an access point, eMachines recommends buying one
designed for the 802.11g standard. This lets you communicate at the fastest
speeds possible and prepares you for the future.
When buying your access point, be sure the model includes everything your
network needs, including:
❂
802.11g support - for next-generation, high-speed wireless communications
❂
Internet security features - such as a firewall to protect your network from
unwanted intruders
❂
wireless security features - such as 128-bit WEP encryption
❂
4-port switch - to eliminate the need for additional network hardware
❂
DHCP server/dynamic IP address assignment - to automatically configure
network and IP addresses
If you use an 802.11b access point, you will not communicate
at 802.11g speeds.

setting up your network
Let’s get started!
In this section, we’ll show you how to set up your home network, using the
previous example of a home environment with an existing desktop computer
and broadband Internet connection.
The setup steps are:
❂
step 1: making sure that your broadband connection is ok
❂
step 2: connecting your new access point
❂
step 3: gathering information about your connection
❂
step 4: configuring your access point
❂
step 5: testing your home network
Throughout this chapter, you’ll be using your desktop computer to
configure the access point and will not use your notebook.
We’ll walk you though connecting your notebook to this network in
the next chapter.
step 1:
making sure that your broadband connection is ok
Before you change anything about your home setup, make sure that your
broadband connection is working properly. To test the connection, just log on to
your desktop computer (in your current setup) and see if you can connect to
your favorite Internet website. If the connection is not working properly, contact
your Internet service provider (ISP).
If you do not have a broadband connection already installed,
make the necessary arrangements with your ISP. Be sure to find
out how soon after the installation the line will be activated.

setting up your home network
step 2:
connecting your new access point
Connecting your access point takes only a few minutes.
You need to follow the instructions that come with your access point, but the
basic steps of installing an access point involve physically connecting the
broadband connection to the access point and connecting your desktop to the
access point.
See the following illustration for an example of connecting the broadband
cable to the access point.
See the following illustration for an example of connecting the desktop
computer to the access point.

step 3:
gathering information about your connection
Broadband Internet settings will differ from ISP to ISP, so before you can begin
setting up your network, you will need to contact your ISP and discuss your plans.
Ask your ISP to help you fill out the following table.
In the spaces below:
Check the box for your type of Internet connection.
Record the information about your connection.
❑ DHCP/automatic IP addressing
❑ static/fixed IP addressing
(typical setup for broadband cable
modem users)
(required by some ISPs)

setting up your home network
step 4:
configuring your access point
Because access points differ, you need to follow the instructions that come with
your access point to set it up. However, the basic steps of configuring an access
point will include: starting up your desktop (your notebook is not yet connected),
opening your web browser, accessing the access point’s browser-based setup
utility, and entering information about your connection and your home network.
If you are unable to connect to the access point’s setup utility,
check your cable connections and refer to the instructions that
came with your access point.
As you set up your access point:
Record the settings for your access point.

connecting to hot spots
A hot spot is a high-speed wireless Internet access point available in public
locations such as airports, airline clubs, libraries, book shops, and coffee houses.
While you are away from your home office, hot spots let you send and receive
emails, surf websites, or access your company’s network.
If you want to access your company’s network through a
hot spot, contact your network administrator for setup
information. You will probably be routed through a VPN
connection for maximum security.
You usually need to sign up to get access through hot spot connections. During
the sign-up process, the vendor will provide you with the necessary connection
information.
To access any new network, the steps are simple: just obtain information about
the network (such as the SSID, password key, and security settings to use) and
enter that information in the Windows XP Wireless Network Connection windows.
See Chapter 3, “connecting to your new wireless network” for sample
instructions.
How safe is your notebook when using a hot spot?
❂
because hot spots typically do not enable any security measures, the data
that you are sending and receiving may be vulnerable.
❂
if any of the files on your notebook are marked for sharing, other users on the
network may be able to access them.

common problems and solutions
The wireless utility icon shows that my wireless is off, but when I right-click the
icon in the system tray and select “radio on” the wireless does not turn on.
Press Fn + F2 on the keyboard to turn the wireless on. This hot key is the master
on/off toggle.
I turned the wireless on, but it takes a while to connect.
When the wireless is turned on, it automatically scans for available connections,
which can take approximately 30 seconds to complete.
My connection on the network seems intermittent.
In addition to other factors, the strength of a wireless connection is determined
by the distance from the access point and structural material that the signal
must travel through (such as walls, cabinets, ceilings, and floors.)
If you cannot relocate, see if you can improve the connection by changing the
channel of the access point.
I can see the network, but cannot communicate, send files, print, or get to the
Web.
If WEP is used by your access point, go to the Windows XP Wireless Networking
Properties window and make sure that both the WAP and the WLAN in the
notebook have matching WEP keys.
I’m in a wireless network, but no available networks are listed in the Windows XP
Wireless Networking utility.
If the network you are attempting to access does not broadcast its SSID, you
need to request the SSID from the administrator and add that network’s
information in to the wireless utility.
You may want to try entering “ANY” as the SSID, which will make the notebook
try to auto-detect the network.
34
720_wireless_booklet.book Page 35 Wednesday, September 3, 2003 4:45 PM
troubleshooting
My wireless network is listed as a preferred network, but it has an “x” on it.
An “x” means your preferred network is not currently available or you are not
currently in range to connect.
frequently asked questions
When I view the available connections, shouldn’t I see the network for my
building?
Because most wireless networks use some form of private identification, their
information is not broadcast out from the access point.
Obtain the SSID and other network information from the network administrator
and use it to manually add that network to your system. After you add it to your
preferred networks list, it will show up as available when you are within range.
Can I connect to my corporate network using my notebook?
Yes, if your company has wireless capabilities incorporated into their network,
you can use your notebook to connect to the network.
Contact your company’s network administrator to provide you with all the setup
information.
How can I print to my printer when it is connected to a different computer on the
network?
It is possible to share a printer across a network, but you have to do a couple of
things first:
—
enable sharing for the printer.
—
install the appropriate printer driver on the notebook.
—
search the network for the printer and add it to your list of available
printers.

type of network is usually small and is often a one-time network, set up between
a few wireless computers to allow them to share files.
To set up this type of network, you need to talk with your friend and agree upon
the wireless networking settings to use, such as the SSID, network password key,
and security settings.
When entering the information into your Wireless Network
Connection Properties windows, be sure to select This is a
computer-to-computer (ad-hoc) network.
Will my wireless network and a 2.4-GHz telephone interfere with each other?
Yes, it is possible for a 2.4-GHz wireless telephone to interfere with the operation
of a wireless network, because they both operate in the same frequency band.
However, the possibility of interference is limited, because telephones typically
scan before choosing the channel to use. If you manually change the channel
on the phone while it is in use, you may cause a conflict and interrupt
communications on the network.
