Turn Your Pc Into a HotSpot;Tether Internet Over WiFi

1. Download and install Connectify.
2. Click on the Connectify logo in the Notification Tray at the bottom right of your desktop (the icon looks like a radio wave).
3. Select the Internet connection you want to share.
4. Now you'll create a wi-fi hotspot: choose a name for your wireless network.
5. Choose a wireless password. The network is encrypted with WPA2-AES encryption.
6. Select "Access Point" mode to turn your laptop into a wi-fi access point; if it's not available you'll have to choose "Ad Hoc", which is less secure and has other limitations
7. Click the Start Hotspot Sharing button to turn on the wi-fi network
8. On the client devices, you should be able to see the new wi-fi network you just created and use standard wi-fi connection instructions to connect to that wireless network.

Tips:

1. Connectify can also be used to extend the range of your home wireless router. Install it on your Windows 7 laptop, connect to your home network and start the hotspot service, and you can extend the wi-fi signal.
2. If you have problems using Connectify with your wireless adapter, try updating the wireless drivers either from Windows Update or your laptop manufacturer's support site.
