Note: If you have a wired Internet connection (e.g., one Ethernet connection in your hotel room) or a 3G cellular data modem for your computer, you can also use Internet Connection Sharing, a built-in Windows feature to share an Internet connection. See How to Share Internet Access (XP), Share an Internet Connection on Windows Vista, or Share an Internet Connection on Windows 7. If you have a Mac, you can Share Your Mac's Internet Connection via Wi-Fi as well.
- Download and install Connectify (from CNet).
- Click on the Connectify logo in the Notification Tray at the bottom right of your desktop (the icon looks like a radio wave).
- Select the Internet connection you want to share.
- Now you'll create a wi-fi hotspot: choose a name for your wireless network.
- Choose a wireless password. The network is encrypted with WPA2-AES encryption.
- 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 (learn about ad hoc wireless networks)
- Click the Start Hotspot Sharing button to turn on the wi-fi network
- 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.
- 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.
- 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.
- See the Connectify.me site for other troubleshooting issues.
