I just upgraded my Macbook Air1.1 to Snow Leopard 10.6.3. All went well except for the internet connection. Went to Network, does not list
any Wifi , "no service in this location". Went to Internet sharing, got this message "Cannot start Internet sharing
, there are no ports available. Choose a different connection to share or turn on another port using Network preferences." Have no idea
how to do either.Any help greatly appreciated.
