I've recently switched from a PC to a new 15" Powerbook and have a query about wireless internet. I got connected to Broadband, but my ISP (BT) only supplied me with a (free) USB modem. How do I connect this to my Airport Base Station? Can I buy a lead to connect the USB plug into an ethernet-ended cable to go into the Base Station, or do I need to get a new modem (if so, what sort?). I'm not sure if i need an ADSL Router or an ADSL Modem (with RJ45 Ethernet port). I though that the Airport Base Station was a router (is it? - what is the difference, if not?). Can I avoid buying another modem? Great machine and operating system - I wish I'd switched ages ago (Always wanted a Mac and thought about buying one when PowerPC first came out!). Thanks.
