how can i see who is piggybacking on my wireless network?

1. logging in to your router, and check your DHCP client list. if i were you, i'd make the wireless network secure (add a security key)
2. encryption to shut them out and you could find them by different ways depending on what kind of system you are using or by your ISP
3. you can't ..it's the beauty of it.
4. While it's easy to see if someone is using your wireless, there's no way to identify who that is. If you don't want anyone hijacking your connection, enable WPA security if your wireless supports it. If it doesn't, enable WEP security.
