Long story short, my girlfriends flat was broken into, her flatmate's laptop was stolen and some of my things. If on the off chance they get through his password, is there anyway to see if they use the wireless? This is on the remote possibility that they are local, as there are some unsavories living nearby. I have admin access through a desktop that was not taken

And if anyone see's a cheap Tissot watch and an ipod classic full off 90's grunge and 70's rock, let me know...
