wireless router connection
I am trying to connect my Netgear wireless router to my imac. I connected one ethernet cord to my modem, which is connected to the imac, and the internet connection is working fine. But I can't access parental controls for the internet. The Netgear instructions say that I need another ethernet connection from the the router directly to the imac, but there isn't another ethernet plugin on the imac. What kind of plug or adapter do I need to do this?
