Alright I need to secure my network. I am up at school living with 3 other roomates in a dorm. we have 4 wirless laptops and my wired desktop. I know how to secure the wireless network so only the 4 of us can use it, but I also want to network my laptop and my desktop so i can access files from either one. I setup a home network between my laptop and desktop and changed the network name from the default. Is this sufficent so that one of my roomates doesn't accidenty get into my network of my two computers?
