So basically where I live we have 3 people all sharing a comcast wifi connection. My computer in not the one with the router. Most of the info I have found on the net has to do with preventing unauthorized people from using your wireless connection, but what I want to know is how do I protect my privacy from the people that are authorized to use the connection. I want what I do online to be private. I'm not talking about doing anything illegal here, but honestly I dont want my roomates, who are girls, (I am a guy,) to be judging me if I happen to want to check out some "adult websites" from time to time. kind of funny, i know. so what do i need to do?
