you could use a pellet gun, or a paint ball gun or maybe nails on the road. I remember the last time someone Pizzed me off I shot his car up with a high powered bebe gun. He had one of those fast and furious cars. not fast enough for my bullets. No but on a more serious note, move the wireless farther away from the road. enable mac for only your mac address. some have a function to where you can turn down the power that its pushing out. I take it you have a laptop, so go out side and see the distance you get on your wireless before it drops off.
Change passwords on router and computers.
Enable wep to the fullest
enable Mac filters
Close any ports u might have open.
install firewall.
unshare your stuff
and refer back to the first part of my post.
Laying the smack down is always my first idea, thats why my boss is sending me to anger management. LOL
