I'm just curious but does anybody know much about routers? I don't have a direct line connection to my lap top, but it has a built in router reciever, and several people in the housing complex around where i currently live are in range and using unsecured routers. This basically means i can use those routers to get online. But i have to ask, are their any things i should be concerned about? Like do i have to worry about using personal information, ie credit card numbers, e-mail addresses, etc, while using somebody elses router, or am i safe?
