I'm looking for all the computer experts out there. I have a wireless network in my house; I have one desktop computer that is directly connected to the modem (I have a cable connection) and another desktop computer that receives the internet signals via a router. I also have a laptop that I occasionally connect to the internet to using the router. My network is unsecured and basically anybody who wants to get on can do so. I'm wondering how I can secure this network, specifically, how do I put a password on my wireless network?
