I just purchased a linksys WRT54G wireless router and have some questions: I need to use it with a PS2, a couple of ibooks and a wired iMac. It set up easily as I just plugged it in and it worked. I used this web page http://garrickvanburen.com/archive/how-to-set-up-a-linksys-router-with-mac-os-x to try and set up a safer network. However, I didn't know much of what to do once I got there. What is the best way to set up a network where someone can't surf without password access and someone can't tap into my network from the cable modem I am using? I have the firewall set up on OSx for both the ibooks and iMac. I have allowed personal file, printer, and iTunes music sharing. What else do I need to do? How do I set up a password access to the network? I tried searching the forums but didn't find much.
