Ok im having trouble with this, I have a brand new iBook with an airport card installed. I just went out and bought an airport base station. At home i already have a network that my PCs use. Downstairs comp Cable Modem connected to internal card NIC card, with rj45 running out to a d-link thingy, that has like 5 ports. Upstairs comp 1 NIC card with rj45 running to D-link Upstairs comp NIC card with rj45 running to D-link All the PCs are connected fine with no problems. I plug in the base station upstairs, then connect an rj45 from the Dlink, to the base station using the ethernet (lan) port. The ibook picks up the base station, but when I open IE web browser it never loads webpages, just sits there. Anyone have any idea what im doing wrong? It keeps talking about airport admin, and airport setup assistant in the book, but I don't see these in OSX.
