My laptop has wi-fi already built in. I had my laptop with me at our friends house to show them some pictures I had taken.
Up came a box saying it had "found" a wireless connection and did I want to connect??

It showed 2 that I could use to access the internet. And also a couple that said secure.
Must have been their neighbors.
Now this makes me wonder if anyone is able to use MY connections?? I have no idea how secure mine is??
