Many smartphones or other devices do not support the same network configuration that is easily shared from laptop to laptop.
This guide can show you a free way to share your network connection with these devices without also needing to install any third-party software on Windows Vista or 7 (though it's possible on XP too). Keep in mind that this works best when your laptop is connected via a cable. Ultimately, this method is ideal for sharing the Internet connection in a hotel room (many rooms have only one ethernet cable) from your laptop to other devices.
All you'll need in advance, besides a working network connection, is an up-to-date version of the Java Runtime Environment installed. You can check whether you have JRE, or even get the latest version here.
Step 1: Open your browser of choice and navigate to www.virtualaccesspoint.com. Note that this page will need to remain open as long as you want to share your connection.
Step 2: Once the page is loaded, a small window will open asking for permission to run an app. This is normal, and you'll need to grant it permission to run.
Step 3: Enter the name for your access point, as well as the desired security key. Click on Turn On Soft AP to create your access point.
