I just got a new iMac 24" I upgrade from the G5 and I was using a wireless connection then but I switched to having a ethernet cable instead of using the airport and I was trying to get to share my ethernet with my airport so I could use my iPod Touch anywhere in the house...plus I have friends come over with their laptops. But I turned on the share internet in the sharing preference and it still doesn't work it says that my airport has a self-assigned IP address and may not be able to connect to the internet...so if anyone has some ideas please just let me know I would appreciate the help
