Hey guys, I'm thinking of getting the Airport Extreme but have a few questions first. OK, if I get the Airport Extreme will I need a modem too? I plan to use it wirelessly.... I don't think I will but I read another thread and it has made me confused about this. My Dad uses a PC so he should just be able to connect to the Airport Extreme on his computer like he normally does to the Netgear, right? I mean, he won't need any software installed will he?
