I'm sorry for the nature of this post and if I'm in the wrong section, but I have a bit of a problem. My mentally disabled son is allowed to use the remote Mabcook to play one application. While we weren't looking he did something to change the settings and now the Airport icon is gone from the top toolbar. I have gone into applications and tired to turn on airport but am unsuccessful. In Airport utility all I get is a message saying: "Airport utility was unable to find any airport wireless devices". Please help and sorry if this is in the wrong place.
