It started when I got a call from the police this afternoon. Apparently, they have tracked a stolen Macbook to my address. Of course, the problem with that is that neither I nor anyone in my home owns, or has stolen a Macbook. So, after all of us had spoken to the police, I decided that someone must be using my internet connection with the stolen laptop. I opened McAfee and my wireless router advanced settings (Shaw - Cisco DPC3825), and sure enough there is a fourth device (MAC address doesn't match any of my systems) that I can't account for. Everything is passworded, so I assume that the person in question has hacked into my connection.
Now, I don't want to just change the password right now, because I want the police to catch whoever it is so they leave me alone, but if I change the password, the link is gone. Instead, I walked around my block with my cell connected to my wifi to see how far the signal would reach. Unfortunately it turned out to reach about 9 other homes. I can exclude one neighbor because he has his own wifi connection, and he has never struck me to be the type to do something like this.
This all brings me to my question(s): Is there any way to narrow down the location of the stolen computer or gain some sort of access to it remotely from a Windows or Ubuntu system? Does anyone know of any material that would block the signal from my router so I could watch the connected devices and see if one goes offline when I block one side of the router? That would help me narrow down the direction of the thief I would think. Of course, I'm no expert, so for all I know the signals may bounce and not do a darn thing to help me.
Anything anyone could suggest would be appreciated. I work in retail and the last thing I need is more stress going into the holiday season. I want to keep my hair....
