I added a free unscrambled wireless port to my internet service. I did it
with multiple routers, so I believe my computers are protected. So far, I
have about 6 or 7 neighbors who use my internet service.
There have been times, when I couldn't afford a proper internet connection.
I figure some of my neighbors may be in that boat.
My only concern is that if my neighbors do something illegal, my door might
get broken down by the authorities before they discover that they are just
looking for one of my neighbors.
It is kind of fun to watch the wireless light flash, when they are on. I
also periodically check the router's log of recent users.
I have neither the technology or skills to see what the heck they are
actually doing on there. One connection was from a Wii, so I guess a kid
was playing video games over the internet.
My own uses have had no related problems. I even stream video without the
extra traffic slowing me down.
