Hi! Our lovely new 24 inch iMac with airport card arrived yesterday. My husband set it up last night and the Safari was working with our D-link wireless airport/router, just by connecting to the default airport and typing in his password. Today, it is not. I know the airport/router is sending a signal because his mac laptop is accessing the internet still. The iMac is showing a signal, but not accessing Safari. We tried typing in the IP address for Google and can't access that either. He's been at this for several hours and is getting highly frustrated. Any suggestions of what we can do to get this thing working. Thanks in advance!!!
