I have an 802.11g Apple Aiport Extreme Router and a Mac Mini (Power PC). I'm trying to set up the router and everything says that it it's working perfectly, full wreless signal and System Preferences tells me I'm connected to the Internet via Airport. Then I fire up Safari and nothing, blank screen then it tells me I'm not connected to the internet. Really got no idea how to fix it cos the computer is telling me it's working perfectly
