Method 1 (Difficult):
Here is a step by step
instruction to use a laptop as WIFI Router and access Internet through it on
any other WIFI enabled device in ad-hoc mode :
1. Go to Start, Control Panel,
Network Connections. Right click the wireless connection (it should be called
“Wireless Network Connection”) and select properties.
2. On the window that will show
up, click on the Wireless Networks tab. Make sure that no wireless networks are
being listed under "Preferred Networks". If you see networks there,
remove them one by one.
3. Click on Advanced
button.Select “Computer-to-computer (ad-hoc) networks only” and click on Close.
4. Now click on Add. It is thru
this window that we will create our wireless network. You will need to fill out
the following:
Network Name (SSID): This will
be the name of your network. This is how your computers will call your network.
Network Authentication: Open.
Data encryption: WEP.
Uncheck the “The key is provided
for me automatically” box.
Configure your network key. This
is a password that will be used to encrypt data transferred on your network,
preventing neighbors from surfing the web for free and also preventing people
to view or even delete your files, if file sharing is enabled on your network.
You must fill this field. The key must have five alphanumerical characters.
5. After clicking Ok, you will
see your network listed under Preferred Networks. Your network will still be
listed with a red “x”, this is absolutely normal.
6. Now you need to share your
Internet connection. Pay attention because this is done on network card that
has your broadband Internet connected, not on your wireless network card. Go to
Network Connections (Start, Control Panel), right click the network card where
your broadband Internet is connected to and then choose Properties. On the
window that will show up, click on Advanced tab.There, check the “Allow other
network users to connect thru this computer’s Internet connection” box and make
sure that the “Allow other network users to control or disable the shared
Internet connection” is unchecked.
7. Click Ok and now you will see
“Shared” under the name of the network connection where your broadband Internet
is connected to (usually called “Local Area Connection”). Your wireless
connection will still be listed as “Not Connected”; this is absolutely normal.
It will only change to “Connected” after any other computer has joined your
network.
8. Now that your host computer
is correctly configured, you need to configure the other computers that will
have access to your wireless network.Now that you have configured the host
computer, it is time to configure the other computers that will have access to
your wireless network. This configuration is very simple; just follow these
very simple steps:
9. If you configured your host
computer correctly, your wireless network will now be listed on the available
networks list of all computers that have a wireless network card within the
range of the card installed on your host computer. Just click the wireless
network icon available on the task bar or double click your wireless connection
on Network Connections (Start, Control Panel) to see a list of wireless
networks available.
10. After double-clicking your
network, Windows will ask you the network encryption key.
11. After clicking Ok, your
network status will be listed as “Acquiring Network Address” and then it will
change to “Connected”.
12. After this point you will
have access to the Internet using the Internet connection available on your
host computer. Test your network by opening your web browser (Internet
Explorer, Firefox, etc) and trying to open a well-known website like Google.
13. Now on your host computer
its wireless connection will also appear as “connected”. Like we said before
the wireless connection on the host computer will appear as “connected” only
when other computers are connected to it.
14. In order to prevent
instability issues on your wireless network, we recommend you to remove all
other networks that may appear listed under Preferred Networks on all
computers. This can be done right clicking your wireless connection on Network
Connections. (Start, Control Panel), selecting Properties, then on the window
that will show up click on Wireless Networks tab. Remove all other networks
listed under Preferred Networks but your own network.
