Hi everybody, I'm not sure if this is in the right place, but I'm having a problem with my iMac. We have a wireless network here and my iMac shows that the Airport card is connecting, but it won't transfer data from the internet. I'm currently using our Macbook to type this over Wi-Fi, so I know it's not the modem. Does anybody have any idea what could be wrong? Anything I need to clear out (cache & cookies have been cleared)? Plz help. I feel lost without my iMac!
