Wifi privacy nightmare in buffalo
Wow this would totally suck. People really need to password protect their wifi. Not that password protected wifi is unhackable but at least it much safer.
BUFFALO, N.Y.
It was a nightmare scenario: A homeowner forced to lie on the floor while gun-wielding federal law enforcement officers called him a pedophile and pornographer.
But the Buffalo, N.Y., man was innocent. Someone else had tapped into his wireless Internet router to download child pornography. The homeowner had gotten frustrated trying to set up a password to protect the wireless signal and paid a heavy price.![]()

All these can be hacked, of course, but it would make it a wee bit more difficult for a lazy wardriver.
Another good idea is to look at what machines are actually assigned ip's by your router. If you only have 3 devices and there are 4 different MACs attached to your network, someone is probably using your network without your permission.
