I have to be careful what I say, but here's the situation.
We have accidentally become involved in an investigation. We are not being investigated, but something we bought for a home computer ended up being part of some crime and it creates some sort of "ping" to another computer alerting the bad guys when this person was on line. We have turned it all over to the authorities yesterday. Now, 3 times today a beat up Hyundai has parked across the street from our house and someone inside keeps looking at our house and fiddles with some sort of computer looking box and then after 10 minutes they drive away. Soooooooooo, I was wondering if they were attempting to hack into our wireless.
