In this clip, learn how to tether your rooted Droid to a WiFi network and use it as a modem for your other Wireless devices. This process is pretty easy and only requires a network and that your phone be rooted.
Just download the Wireless Tethering APK to your computer and transfer it to your SD card, preferably the root.
After you are done doing that use the app EoEinstaller to install the APK file to your phone just as you would a market app.
