I just purchased a new laptop with wireless capabilites. I am pretty much clueless about wireless. I have no router, yet I was playing with my new machine and discovered that I could connect to the internet through a linksys unsecured network. I mean the new system (Windows Vista) basically says to connect to it but I started thinking where did this come from?? Am I cutting into someones router somehow? When it says it is unsecured does this mean that someone can see what I am doing...like if I do online banking??? Please help me understand this and thank you.
