ok heres the deal - i just bought my iBook on saturday (mind you i am completely new to the mac world, just switched from a pc) and the apple store employee told me how to set up the internet but i cant remember what he said and ive been playing around trying to figure it out for two days and i cant. i have sbc yahoo dsl and currently its hooked up to my old pc. i dont want both of them connected at the same time, i just want my iBook hooked up to it. i go to my system preferences and click network and i have no clue how to set up any of the information that it requires. i used the sbc yahoo booklet that explains how to set it up on os x but it only lets me get as far as confirming my sbc account (which i am online during) but after that it wont let me use internet explorer. yes the ethernet cable is plugged in. ANY advice on what to do / what im doing wrong / comments would be greatly appreciated. please help me!
