Answer
If your device is running WPA2 with AES and it was set up correctly your neighbor didn't get into it unless they already owned your network.

To prevent someone from using your Wifi run WPA2 with AES and make sure the device doesn't have a known vulnerability.  If it has a patch available, assume it has a vulnerability unless you've installed the patch (or the upgrade).
