This page will show you how to convert your computer into a (Public) HotSpot.

The goal you want to achieve here is:

1. take a computer connected to the Internet (via a Local Area Network  or an ADSL connection) and with a wireless card;
2. convert this computer into a HotSpot so that wireless enabled devices can connect to the Internet via your computer.

In other words you want to make your computer able to share its Internet connection across Wi-Fi.

Windows XP and Wi-Fi

Windows XP provides both wireless adapter drivers and their related client software (i.e. the software required to configure and use Wi-Fi). In other words Windows XP makes it possible to plug in a wireless adapter and begin surfing the net in a seamless way, without installing any additional software. In alternative you can install and use the software supplied with the wireless card or that you have downloaded from the card vendor’s website.

This page explains how to convert your computer into a HotSpot by using the standard Windows XP drivers and client software.

1. Make sure the wireless card is on

Before trying anything, you should make sure the wireless card is on.

Wireless Network Icon

If your wireless card is on, you should see an icon like this one in your task bar.

2. Make sure Windows XP controls the wireless subsystem

This page contains instructions on how to connect to a HotSpot using the standard Windows XP drivers and client software (and not any vendor specific driver or software). So you have to make sure that your computer uses the standard wireless support provided by Windows XP.
