Hey everyone - I'm relatively new to Macs and I have a question about network security. I'm going back to college next month with my personal wireless router (the dorm isn't already wireless). I plan to hook the router up to the hard wire in my room, and it should work great. Problem is there are about 30-40 people who will be in range of my router! I don't want them on my network for security reasons, so I was wondering if anyone knows how to encrypt my signal. I have a Linksys Wireless-G router. Thanks for any help!
