The dorm I'm in doesn't have Wifi, which is a problem, because both my iPod and printer need a wireless network. So I'm sharing my connection from an ethernet cable over Airport, and both my printer and my iPod can pick it up. However, my roommates, who are equally frustrated by the lack of wifi in our apartment, cannot connect to my network, which is encrypted. Both of my roommates have Dell laptops - one is an older laptop which runs Windows XP, and one is an newer XPS which runs Windows 7. I myself have a 13' MacBook Pro, if any of that information is relevant. I would like to know how to get their computers onto the network so I don't feel so bad having internet while they don't.
