I have never heard of anything like this, but it seems to be true. My college wifi network uses some protocol that seems only accessable by windows computers running XP. I don't know too much about servers and networks etc, but from what I gathered from the website its something called a "Cisco PIX firewall" and a "Microsoft Internet Security and Accelleration (ISA) Server". I'm pretty pissed to discover this. I'm a communications student, and we have a building with thousands of dollars worth of G5s for video/audio editing. Why on earth would they block out a platform that they teach their students to use? Can anyone tell me for sure if i'm SOL here? Is there no way around this? I'm very good with computers, and can usually figure things out on my own, but this has me baffled. Airport reads that it's recieving a signal, but i'm not getting any internet connection. Theres a long instruction list to get connected, which involves lots of hoops to jump through, but like I said, it's for Windows XP. I bought a mac for alot of reasons, one of them being the fact that it's the platform I use at school, and, while i'll live if its the case, i'll be very angry at my school if I can't get connected. Its a resource all the students are supposed to have access to, and I pay tuition just like everyone else. Any help is appreciated. Thanks!
