sorry for asking this here, but...
lets say there's 2 people living in a house. they get wireless DSL internet. person A has the wireless setup in their room and the main account setup on their computer.
person B, has their computer in a whole other room and just links onto the wireless signal and accesses the net via their own browser.
could person A track the activities (without in depth software)of person B? even chat logs like on MSN messenger?
is there an administration setup already on the account that would allow this? every website and even find out passwords?
i am concerned thatperhaps this is being done to me.
