Hi, I have a home network of 3 windows XP pc's sharing a broadband internet connection. I have an alcatel speedtouch USB broadband modem going into the host pc. I am new to macs and have just bought a new ibook and an airport extreme card. I have just been given a friends old graphite Airport and would like to somehow make it work off my windows network so i can browse the web with my ibook wirelessly. This is where i have been having problems. I initially plugged a network cable from my home network (ethernet) hub into the back of the Airport and installed the Airport admin utility for windows (1.0) onto the host pc ( the one that has the broadband going directly into). However when run the Airport Admin Utility no airport is shown? and I can't see that my computer is accessing it at all. Have i got all the hardware i need? If someone can help me with a walkthrough it would be an amazing help! I am a complete wireless noob and am as lost as a lost thing in Lostville on lostday. Help!
