Let’s say you have a laptop that is
equipped with both ethernet(wired) and wireless network adapter and it
is connected directly to the Internet using an ADSL modem. Now your
younger brother also bought a new laptop and wants to use the Internet.
Instead of spending money in buying a wireless broadband router, you
can save up the money and share the Internet from your laptop using the
built-in wireless network adapter.

If you have a desktop computer that don’t have built-in wireless
adapter, you can buy a wireless adapter for less than 800\- or 10USD and
it is so much cheaper compared to a router. Here’s how to share
Internet connection from your laptop or desktop that is equipped with
wireless adapter.
First we’ll need to setup the HOST computer. HOST
means the computer that is directly connected to the Internet via ADSL
modem and it will be the one that is sharing the Internet connection

. Go to Control Panel > Network Connections, you should see a
Local Area Connection, Wireless Network Connection and a connection
dailer (I use Streamyx). In detailed view mode, it shows a lot of
useful information regarding your connections.

Below are the steps to configure the HOST computer:
1. Right click the connection which you use to connect to the
Internet and select Properties. Go to Advanced
tab and check “Allow other network users to connect through
this computer’s Internet connection”
2. Click the drop down menu and select “Wireless Network
Connection“. Click OK.

3. Go back to Network Connections, right click Wireless Network
Connection and select Properties.
4. Go to Wireless Networks tab.
5. Click Advanced button, select
Computer-to-computer (ad hoc) networks only, and make sure that
Automatically connect to non-preferred networks is UNCHECK. Close it.

6. Click Add button and Wireless network properties
Window will appear. Enter any Network name (SSID), and change Data
encryption

to Disabled. You can change it to WEP when everything is working
fine.

7. Right click at the wireless adapter

icon from system tray and select “View Available Wireless
Networks“. Select the Network name (SSID) that you entered at
step 6 and click Connect.


The HOST configuration is done. From what I read on most guide, step 7
above is not necessary but don’t know why if I don’t do that, the
CLIENT won’t see the HOST in the wireless network list.
Next, we’ll need to configure the client computer now which is very
simple. CLIENT computer means the laptop or desktop
that will be connecting to the HOST computer.
1. Right click tray wireless adapter icon from system tray, and
select “View Available Wireless Networks”. Select the HOST computer and
click Connect.

The client computer will automatically acquire IP address from HOST
computer because Internet Connection Sharing is enabled. It might take a
while, so be patient. Now both the HOST and CLIENT computer can
connect to Internet and also share files with each other. See, sharing
Internet without wireless router wasn’t so hard now, was it
have fun save money
