Making the Wireless Home Network Connection in

Windows XP Without a Router

I've received many inquiries from Windows XP residential users asking how to wirelesslynetwork a second or third computer without the expense of a wireless router or a router and a

stand-alone wireless access point (WAP). his is sometimes called an ad hoc wireless

network. !uilding an ad hoc "#$.%%& wireless network using the graphical user interface in

Windows XP takes 'ust a few minutes. !ecause its powered &y wireless ero configuration*

you wont need to run a single ca&le or hunt for an electrical outlet+ Add ,nternet onnection

haring on the host computer and all connected computers will &e surfing the net wirelessly

in no time at all.

Well start with a single computer that already has a wired /thernet &road&and connection to

the ,nternet. hen well &uild the ad hoc wireless network in three steps0

%

.

he first step will &e to install an "#$.%%& wireless card in the main computer and configure

it as a computer-to-computer (ad hoc) wireless connection.

$

.

he second step will &e to install a wireless card in a second computer.

1.o complete the network and pro2ide connecti2ity to the ,nternet* ,nternet onnectionharing (,) will &e ena&led on the host.

As you read through the procedures &elow* note that the accompanying images are captured

from &oth the host and client computers and that the screen shots of the host computer

contain a sil2er title &ar* while the client computer screen shots contain a &lue title &ar.



Configuring the Host Comuter

After you install an "#$.%%& adapter (such as an 3rinoco or isco wireless network card) on a

computer* Windows XP will automatically detect the card* install dri2ers* and display an icon

in the notification area. (, am using Ageres 3rinoco il2er cards to construct the ad hoc

wireless network here. Although they ha2e nati2e* in-&ox support in Windows XP* these cardscan &e updated with e2en newer dri2ers and firmware through 4icrosoft 5pdate). ,f the

computer is in an en2ironment where other wireless networks are in range* Windows should

display a list of a2aila&le networks automatically. 6owe2er* if no wireless networks are in

range* the wireless connection icon may display a red 7X8 and may not automatically open a

!iew Wireless Networks window. o open this window* click the icon for the wireless

connection.

9o not select an a2aila&le network at this time if any are displayed in the "vaila#le networks

listing. ,f your computer pre2iously connected to a preferred access point* remo2e all

preferred access points. his will ensure that a connection is made only to the ad hoc network

that you are trying to configure.

$igure %

:ext* click the "dvanced ta& at the top of the window. elect Comuter to comuter &ad

hoc networks only and clear the "utomatically connect to non(referred networks &ox if

it is selected. his setting* along with remo2ing preferred networks* ensures connection to the

ad hoc network only.

lick the Wireless Networks ta& again. 5nder Preferred :etworks* click "dd* as shown in

;igure %. ,n the Wireless Network Proerties dialog &ox* specify a Network name &))I*.

5se any name desired* &ut &e sure to use it to configure all computers. :ote that the network

type is already marked as a computer-to-computer network and that this cannot &e changed

since it has already &een specified that a connection should &e made to only ad hoc networks.

$igure +

Wireless /qui2alency Protocol (W,P) settings are not &eing configured at this time &ecause

its easier to get an ad hoc wireless network running smoothly &efore attempting to configure

W/P data encryption. he decision on whether or not to use W/P should &e &ased on your

en2ironment. ,n most cases* for optimum protection and security* after your ad hoc network isrunning properly* you should return to Wireless Network Proerties and specify W/P

settings.

After configuring the network name (,9) in the Wireless :etwork Properties dialog &ox*

the new ad hoc network will &e displayed with a P ard icon to designate that this is a

computer-to-computer network.

$igure -



:ote the red X. When a second computer is in range and the new ad hoc network is

connected* the display changes to show a working computer-to-computer network without the

X.

Configuring a Client Comuter

After installing an Agere 3rinoco "#$.%%& il2er P ard in a second computer* the Wireless

:etworks ta& displays a list of in-range wireless access points or ad hoc wireless networks* as

shown in ;igure <.

$igure .

he new ad hoc network aloha.-+% is listed (and is identified &y the P ard icon).

6ighlight the network name* and then click Configure. !ecause W/P will not &e configured

at this time* click /0 .



)haring the Connection

:ow that a successful ad hoc wireless network has &een created* well set up ,nternet

onnection haring.

3pen Network Connections on the host computer. (lick )tart* click Control Panel* click

)witch to classic view* and then click Network Connections.

lick the connection to &e shared* and under Network 1asks* click Change settings of this

connection.

3n the "dvanced ta&* select the "llow other network users to connect through this

comuter's Internet connection check &ox.

,f you are not using a third party firewall and ha2e not already set up the Internet

Connection $irewall &IC$* &e sure to check the &ox ena&ling this feature. (=ead more

a&out why to ena&le ,; in an earlier column* 9ont >et the 9efense =est.)

;inally* optionally ena&le the setting to let other users control or ena&le this connection.

After completing , configuration* the Network Connection window on the host computer

will display the original wired /thernet connection and display the status as )hared as well

as ,na#led. he :etwork onnection window on the client computer will display the

connection on the host as an Internet 2ateway.

$igure 3

he client computer(s) should now recei2e a pri2ate class* non-routa&le ,P address in the

%@$.%".#.B address range 2ia 96P from the host computer and should ha2e full ,nternet

connecti2ity.

Configuring W,P

As connecti2ity has now &een esta&lished successfully* the next step is to return to Network

Proerties and configure W,P settings to ensure the &est security possi&le for the ad hoc

network.

3n the host computer* open the Wireless Network Proerties dialog &ox and select the *ata

encrytion &W,P ena#led check &ox. onsult the documentation pro2ided &y your wireless

card manufacturer for the key format and key length.

$igure 4

5se the highest le2el of encryption possi&le (key length) that is supported &y your hardware

and dri2ers. Ageres 3rinoco il2er cards are used here* and only support <-&it W/P (also

known as <# &its). 5sing the latest dri2ers and firmware* Windows XP actually automaticallydetects that this hardware only supports <-&it encryption and will not allow setting the key



to %$" &it. !e sure that if you use an A,, network key that you pick random characters and

letters that cant &e easily guessed. he final step is to use the same key and encryption

settings and configure the client computer(s). :ote0 for additional security* consider changing

the key on a regular weekly &asis.

Instant Private Networking

:ot only does ad hoc wireless networking pro2ide a lower cost method to share an ,nternet

connection than a more expensi2e wireless routerCrouter plus separate access point solution*

&ut it affords a fast and simple way of esta&lishing a means to share data and documents for

groups with no external >A: or ,nternet connection. With no a2aila&le 96P ser2er*

Windows XP pro2ides an automatic pri2ate ,P address &etween %@.$?<.#.# and

%@.$?<.$??.$?? to network adapters. ,f youre sitting around a conference ta&le with a group

of colleagues and find that e2eryone is in desperate need of a Power Point presentation on an

associates computer on the other side of the room* setting up an instant ad hoc wirelessnetwork can &e the solution* allowing e2eryone to copy the file to their computers o2er the

wireless network. Doull need to ha2e the same workgroup configured with appropriate

permissions for file and print sharing* and youll ne2er ha2e to wait again to get connected to

the ,nternet or a corporate >A: to recei2e copies of urgently needed documents.
