Turn your Windows 7 laptop into a Wireless Access Point - FREE
Why you need it:
You have to setup an impromptu wireless access point to share files, internet, etc. (I use this with my built-in wireless 3G modem to create my own personal MiFi type connection.
What you need is:
- PC running Windows 7
- Working wireless adapter (some intel ones don't work).
- Connectify Me Software (free beta).
Just download the roughly 1.5MB software and run to install it. You just need to pick a WiFi name, a passphrase, and the internet connection access and whether you want to turn on the hotspot you've just created or turn it off.
