Can someone help me please? I'm an idiot at this stuff. Got new white Macbook today. Purchased linksys wireless router Wrt54gs and can'y figure out how to make either of them work. Turned on Macbook, got up to the place in system assistant where it asks how I will connect to the internet and I'm stumped already. Do I select airport wireless, even though I don't have an airport router? Should I configure router first before setting up macbook? How do I configure router? Do I need computer IP address? Where do I find it? I'm so lost my head is just swimming. Right now I have a desktop PC connected to internet via cable modem. I've never felt so stupid in my life. I'm an old lady which probably doesn't help.
