Things to do to prevent such occurrences ...

1. Enable WEP encryption (or whatever encryption your wireless equipment 
supports).  This isn't fool proof, but it will prevent casual intrusion.

2. Change your SSID and disable SSID broadcast.  This will make it 
harder for people to connect.

3. Enable MAC address security ... it's a bit of a pain, but will 
prevent people from using your connection without permission.

4. Change your wep keys and ssid periodically.  This will make it even 
harder for someone to intrude.
