I have a lot of neighbors that have their wireless networks just broadcasting away unprotected. My Motorola Droid sometimes wants to connect to the networks that don’t belong to me. You can tell the Droid to forget the networks you’ll never use.

1. From the main screen, press Menu.

2. Tap Settings.

3. Tap Wireless & networks.

4. Tap Wi-Fi settings.

5. Tap and hold the name of the wireless network you wish to forget.

6. Tap Forget network.

For some reason I could only do this with unsecured wireless networks.
