How exactly does it work when you have multiple machines connecting to your wireless router that is not secured. Let's say on my wireless network card I find a few strong signals I don't recognize that don't have the lock next to it. What happens when I connect? Does the owner know I'm connected, will I know if others connect?

the owner will know your connected and can kick you off the network I dont think other computers b/s the owner can see u thoe. I use to do it with my laptop all the time thoe when I lived in the baracks its way better than paying for internet.
