I have a new MacBook OS X 10.5 and Windows XP SP2 (using boot camp). My internet connection is dialup through my iMac OS X 10.4 with external modem. I am set up with a home network using firewire. I also set up a network using airport, which shows as connected, but not able to see other computer. I am able to access the internet on my MacBook logged into Windows via the wireless network. I am unable to access the internet at all logged into OS X on MacBook. I have been able to complete the wireless network using airport and can access my iMac from MacBook, but still cannot access internet except when logged onto windows on MacBook. watsup?
