Can anyone help with an airport connection problem? I have an iMac 9.0 os. The instructions to install an airport card w/adapter do not match the inside schematics of this imac. Is there an airport card in this imac already? I have checked the apple extras folder for the airport installation progragm and It is not there. Any suggestions would be greatly appreciated. I have wireless roadrunner and I am trying to set this imac up for connection. Thanks.
