I just got wireless on my laptop, so I dont know much about it. My parents laptops use the same wireless connection, so i was wondering, can they see what I'm doing/where I've been/ or my browser history on their laptops? and vice versa?
wireless connection = lan cable connection more or less.
depends on the settings of your firewall and router. And generally to see the history of your browser, they'd have to get into your pc, and from there found the place where browser history is stored. And generally unless hackers or something, they could get maybe into your public sharing folder.
But who knows, maybe your parents do have a filter for some words on your router (if it allows) and thus blocking you access to some certain words with the name included.
