Hi all, I am not terribly tech-savy, and have a question. I set up a wireless network at home (pretty figgen easy, it was pretty much plug-n-play). The network is not protected, though. How do I protect my wireless network? There was no "install" to do, there was never a choice for requiring a password.

Any thoughts? Oh, and don't ask what kind of anything I have at home, because I have no idea off the top of my head.

Thanks!
