alright, in a nutshell, how much damage can be done to me/my life/computer with a wireless router? and what steps could I take to prevent them? long story short, my girlfriend got a laptop for a graduation gift, I bought a Linksys Wireless-G Broadband Router with SpeedBooster(whatever the heck that is) so that she could get on her laptop and me be on the desktop. When she first got her laptop, she was picking up connections in the area and was able to get on the internet. That tells me that people in my area (as podunk as it is) have wireless computers. Is there a way to limit who can get my connection? and the most important questions: if someone advanced enough comes in this area, can they actually do anything to my computer? can they steal my passwords/information, see what I'm doing? actually put stuff ON my computer? or do they just simply take away some of my bandwith? or am I just being completely paranoid in the new "times" of today? thanks for any help in advance.
