You guys are going about it all wrong (unless they have a crazy insecure and old router)... radio jamming is the way to go.
make one, if you cant be arsed just cut a hole in the side of a microwave oven and point it at them on high :)
Well safety procedures should be observed, when you hear screaming turn it off until the screaming subsides.
