Hello experts out there! I am planning to subscribe to cable broadband here in UK, and the broadband company told me that as I am a mac user, I need a Network Interface Card for me to get connected. HELP! 1. What is a network interface card? 2. Do I have a network interface card? Don't think so. I am currently using a 1.5gig G4 powerbook. 3. Where can I get one? is it better for me to get one? or will it come with a router? (coz I am planning to get a router so I can share my internet connection with my flatemates) Please help! I am totally clueless!
