Okay, i'll try to explain what I mean. When I access my router (you know where I can change different settings on the router and stuff, like firewall, etc etc) there is a section where you can see all of the devices using (or that have used) that routers connection. NOW, I don't want to appear on that list when i'm using the internet. Is there a way that I can make my Macbook not show up with some sort of invisible mode or something? Where no one can see that my macbook is using that connection? And btw i'd like to appear invisible to other macbooks as well, like not show up in their list of shared networks or whatever. I want to be completely invisible to others as if I didn't exist. Any kind of help would be greatly appreciated.
