I'm trying to connect my PC notebook to the internet via built in Airport on my Intel Mac. All systems seem to be on go; the signal strength on the Mac is at 100%, and the PC indicates the signal strength is very good, and the status reads connected. However, I can't connect to the internet on my PC. The only indication of something troubling is the fact that the bubble next to AirPort is red in the Mac Network Status, but it indicates Airport is connected to the Computer-to-Computer network. I have no idea what's wrong or how to get my PC to connect to the net, so any help would be greatly appreciated.
