Okay, I just setup a wireless network and I can access and join the network from both my mac and my roommates PC. How do I set up a password for entering the network? Everyone these days are stealing connections because they are not password protected but I don't know how to set up a password for access. Can someone help? I tried using airport admin utility but it doesn't find the base station. I'm not using an airport base station but a linksys wire router. Thanks!
